President’s welcome

Hello all and welcome to this Spring Edition of Pump Industry Magazine.

At the time of writing three events were planned with Breakfast Meetings in Sydney and Melbourne, and an Installation and Commissioning Course in Melbourne all scheduled for September. In July, we held a very successful Technical Meeting in Brisbane in conjunction with Irrigation Australia (IAL) at its premises in Murarrie. The topic was ‘Training Towards a Sustainable Pumping and Irrigation Future’, and was attended by 30 members and non-members alike.

The purpose was to find out what IAL and its stakeholders are doing to ensure that they have enough qualified and certified people to cope with the increasing demand in the irrigation industry; Geoff Harvey of IAL did a presentation on its two-day Irrigation Pumps and Systems Training Course and Path to Certification.

Further to this, IAL has extended an invitation to PIA members the opportunity to send suitable persons to its next two-day course titled ‘Irrigation Pumps and Systems’, to be held in Brisbane on 15 and 16 October, where PIA members would pay the same fee as IAL members through our MOU.

This leads me to the question: Why can’t our industry have similar training courses as a Path to Certification?

Imagine if we were able to offer a Certificate III in Pumping covering different competencies including selecting pumps, reading friction loss charts, installation, troubleshooting, commissioning – the list goes on.

IAL has done its very successfully but it has taken a few years to get there. IAL as the peak national organisation for the entire irrigation industry is a Registered Training Organisation (RTO 91313) under the name Irrigation Training Australia, providing the industry with nationally accredited training and qualifications.

This question was put to the attendees at Murarrie and the answer was a unanimous YES, with a number coming up to me after saying they would support it. To follow up on this thought, Council at our last Hot Air Meeting held on 30 July agreed to ask IAL to scope a PIA competency-based training program specifically for the pump industry.

IAL is willing to do so and it is hoped that in the future we might also be able to offer an Accredited Pump Training Course leading to a recognised Australiawide certification/qualification under the umbrella of IAL as an existing RTO.

IAL is working on this for us and it is hoped we will have something for Council to consider in the coming weeks and maybe even to present at the AGM in November.

The benefits to PIA members would be enormous, bearing in mind that part of our mantra is that PIA endeavours to encourage the ongoing development of our industry.

In recent editions I have commented on the shortcomings of the selfregulation and certification processes in the building industry.

Well if you watched the excellent Four Corners program on Monday 19 August entitled ‘Cracking Up', it is clear to see where this self-regulation has got us.

Just three days into his job as NSW Building Commissioner, David Chandler stated some of the units he investigated were “of the most poorly built he had seen”. It appears that the problem does not just lie with the privatisation of the Building Certifiers; it seems the whole system is flawed from the planning stage through to the engineering design to the construction of and finally certification.

Fortunately not all designers, engineers, building companies and certifiers fail in their responsibilities, but there are enough to give the industry and legislators serious problems.

Those in the fire industry need to ensure they don’t fall into the same category.

This was highlighted at the recent FPAA seminars co-sponsored by PIA in Melbourne (100 attendees) and Sydney (169 attendees) in July titled ‘Fire Pumpsets: Selection, Installation, Commissioning and Servicing’. Both were well patronised, demonstrating the huge interest in this area. Ken Kugler, our Executive Officer for Standards, was one of the presenters.

FPAA is planning a repeat of the seminars because of the high interest shown and will likely run in other states.

As you know, we continually seek to increase our membership, so I ask that if you know someone who would benefit or be able to contribute to PIA, please extend an invitation for them to join; the more members we have, the more relevance we have and more importantly it extends our knowledge and skills base. Any ideas or thoughts you have to improve PIA please make yourself heard; we need and welcome your input.

INDUSTRY

The Australian manufacturing industry is at a crossroads. Transforming the materials we dig up or grow into the products we use every day requires enormous amounts of heat, and rising electricity costs and inefficient processes means many businesses have seen their gas and electricity bills double over the last two years. A report from Beyond Zero Emissions shows there are opportunities for manufacturers to reduce costs by generating heat through the smart use of renewable electricity, with heat pumps one technology that they can take advantage of.

SMART PUMPS

Jail sentence for solar heat pump INSTALLATION FRAUD

The Brisbane District Court sentenced a plumber to four and a half years of jail time for fraud and production of false and misleading documents claimed he had installed more than 400 solar heat pumps.

The sentence, handed down on 5 August 2019, is the result of an investigation by the Clean Energy Regulator (CER) relating to the Small-Scale Renewable Energy under the Renewable Energy Target.

Brett Stephen Muldoon, who will serve a minimum term of 15 months before being eligible for parole, obtained just under $400,000 by producing false and misleading documentation claiming that non-existent solar air-source heat pumps had been installed at more than 400 properties throughout Queensland.

This enabled him to improperly create 11,180 small-scale technology certificates between 2013 and 2014.

In sentencing, Judge William Everson stated this was a sophisticated fraud, noting the length of time of the conduct and the amount of money taken.

Judge Everson said “a deterrent sentence is called for fraud of this magnitude” and that Mr Muldoon’s conduct was “extremely selfish and reprehensible”.

Mr Muldoon’s conviction was under s408C of the Queensland Criminal Code. The one charge accounted for 415 acts of fraudulent behaviour committed by Mr Muldoon.

The CER requires a high level of compliance with scheme obligations, and has a range of monitoring and enforcement powers under legislation.

Fraudulent activity, such as providing false information to create small-scale technology certificates, is a threat to the integrity of the schemes administered by the CER.

The CER warns that individuals and companies who participate in the schemes and wilfully commit an act of fraud or non-compliance, such as falsely creating certificates, will be subject to enforcement action which may lead to criminal conviction and jail, as in this case.

‘Flushability’ trials to help inform national standard

Queensland Urban Utilities is undertaking a new trial to test the ‘flushability’ of products like wipes, cotton buds and paper towels, in a bid to help create Australia’s first national standard for products that want to claim the label of ‘flushable’.

Testing has started in Australia’s largest replica sewer at Queensland Urban Utilities’ Innovation Centre at the Luggage Point Resource Recovery Centre.

Queensland Urban Utilities spokesperson Michelle Cull said scientists were using the one-of-a-kind facility to study how wipes break down in the sewer network.

“Wipes don’t disintegrate quickly like toilet paper and can cause blockages not only in your household plumbing but our sewer network,” Ms Cull said.

“Creating a new national standard will lead to clearer labelling and give consumers confidence that they’re only flushing products which will break down after they’re flushed.

“Until then, the best advice is to only flush the Three Ps – pee, poo and (toilet) paper.”

In 2018, Queensland Urban Utilities removed around 120 tonnes of wet wipes – which is the equivalent of 34 hippos – from the sewer network.

Queensland Urban Utilities sits on the Water Services Association of Australia (WSAA) Standards Committee, which is hoping to have the new national standard finalised by the end of 2019 to replace industry self-regulation.

The national standard will cover the ‘flushability’ of not just wipes, but other disposable products such as tampons, cotton buds, kitty litter, paper towels and single-use toothbrushes.

Sydney Water’s new procurement strategy looks to partner for success

Sydney Water has developed a new procurement strategy, called ‘Partnering for Success’, which will see a new Regional Delivery Consortia appointed to manage design, construction and maintenance and facilities management in each of its three regions (North, South and West) for the next ten years.

The strategy also includes Shared Purchasing, which will simplify how Sydney Water and its partners will procure specialised goods and services that can’t be self-performed.

Sydney Water’s area of operation will be divided into north, south and west, and the consortia will be responsible for operations in these areas for the next ten years. Further to this new procurement approach, Sydney Water has also entered into a long-term partnership with Aurecon and ARUP who will work with the Integrated Systems Planning team to form a truly integrated planning function, bringing the right mix of capability to co-create projects and deliver plans successfully.

The integrated team will also perform technical assurance and project engineering. This will ensure that planned benefits are realised through delivery and maintenance.

Aurecon’s Global Head of Water, Kevin Werksman, said water utilities were increasingly seeing the benefits of the partnership model as being able to much better leverage value in a collaborative, non-transactional environment.

“As well as additional technical engineering smarts, Aurecon and ARUP will provide additional advisory services such as asset management and community consultation,” Mr Werksman said.

The integrated team will also perform technical assurance and project engineering. This will ensure that planned benefits are realised through delivery and maintenance.

Shared Purchasing is a new approach adopted by Sydney Water to simplify its procurement of specialised goods and services.

Some day all motors will be this efficient. But why wait?

The idea is beautifully simple. Combine conventional stator technology and a magnet-free rotor design, take a top-of-the-line industrial drive and software, and optimize the whole package for variable speed pump and fan applications. What you get is the performance of a permanent magnet motor at IE4 efficiency and the simplicity and ease of service of a regular induction motor.

First requests for tender have been sought for pipes and fittings, and valves and actuators.

Additional RFTs will be issued on eTender for:

• Pump supply and servicing

• Plant equipment and hire

• Waste management services

• Electrical goods and services

• Network support

• Industrial cleaning

Head of Supply Chain and Property at Sydney Water, Xavier Decomps, said, “Shared Purchasing simplifies how we and our partners will procure specialised goods and services that can’t be self-performed.

“By pooling our purchasing in this manner, we’ll achieve economies of scale, increase our buying power and develop deeper relationships with preferred suppliers throughout the entire asset lifecycle.”

Under its new Partnering for Success model, Sydney Water and its partners will use a series of NEC4 contracts to procure these and other specialised goods and services.

Sydney Water has been an early adopter of the NEC4 suite of contracts to support the rollout of its new procurement strategy.

Head of Delivery Management at Sydney Water, Mark Simister, said Sydney Water is the first major infrastructure company in Australia to use the NEC4 contract approach to deliver new works.

“The contract will help simplify our supply chain and deliver significant benefits to Sydney Water as an organisation, to our customers and to our partners, through increased efficiency, cost savings, continuity of work, resource availability and partner capability by incentivising high performance and increasing productivity.

“By doing this, we’ll give our partners more certainty, and drive better decision-making across the whole lifecycle of our assets, improving our productivity and delivering value for our customers.”

NEC4 Chairman, Peter Higgins, said, “Our contracts have already been used to great success on water projects across the world, and we’re confident that Sydney Water will achieve the same results as our other partners.

“NEC’s fundamental principles of risk management, alliance and transparency align perfectly with the New South Wales Government’s recent ten-point plan for infrastructure delivery, and the alignment in economy, government and language makes Australia a key growth market for us.”

Sydney Water is looking to not just change the way it procures services, but to transform the way that it does business.

In March 2019, Sydney Water was recognised by the UK’s Institute of Civil Engineers (ICE) for becoming the first international organisation to adopt the principles of ‘Project 13’ for the rollout of P4S.

Project 13 is an industry-led movement to improve infrastructure delivery, so it provides better outcomes for customers, whilst moving to a more sustainable and collaborative business method.

ICE’s Director General and Chair of the Project 13 Board, Nick Baveystock, congratulated Sydney Water for being the first international adopter of Project 13. Mr Baveystock said he was delighted to see Sydney Water embed the Project 13 principles into its work on P4S and help the delivery of infrastructure move from a transactional business model to a more collaborative and sustainable one.

Mr Simister said, “The appointment of the three Regional Delivery Consortia in our north, south and west operational areas will see the need for organisational transformation to support, enable and integrate the Regional Delivery Consortia.

“Given the decade-long term of these contracts, this is a once in a generation change which will have a lasting impact on Sydney Water, the industry, and its customers.

“The scale, complexity and impact of this change cannot be underestimated and, done right, will create an enduring legacy.

“This approach will help the delivery of infrastructure move from a transactional business model to a more collaborative and sustainable one, which will focus on customer outcomes, bring together skills and technologies in a collaborative environment, properly integrate teams across projects, and foster long-term relationships.

“Regional Delivery Consortia Contracts will be awarded to the three successful consortia at the end of the year with a ‘go-live’ date of July 2020.”

Australia’s largest sewage storage facility completed

Yarra Valley Water has completed construction on Melbourne’s new Craigieburn Sewage Transfer Hub, a critical piece of infrastructure which will service up to 420,000 people in Melbourne’s north.

The $69 million project will service developments between Craigieburn and Wallan, allowing Yarra Valley Water to collect, store and transfer sewage to the metropolitan sewerage network for treatment.

The Hub comprises two 15 million litre glass-coated steel tanks which are both the size of six olympic-size swimming pools and are the largest tanks of their kind in the southern hemisphere.

More tanks with a total capacity of 210 million litres will be added as the population of the area continues to grow.

Yarra Valley Water Managing Director, Pat McCafferty, said the Hub is innovative because it can be expanded to keep up with growth in the region.

“The Hub is an adaptive piece of infrastructure which will expand with development in the area. It’s also a much more cost-effective solution than building a large sewer at twice the cost.

“Building flexible infrastructure which can grow with the community allows us to invest money where it’s needed most, while still ensuring we’re able to service the community for years to come,” Mr McCafferty said.

The enormous project provided 15,000 hours of employment and experience for apprentices, trainees and engineering cadets.

Melbourne’s northern growth corridor is one of the fastest growing areas in Australia and the Craigieburn Sewage Transfer Hub is just one example of the vital projects that Yarra Valley Water is undertaking in the region.

Mr McCafferty said that Yarra Valley Water is working hard to deliver the infrastructure that Melbourne’s northern growth corridor needs.

“It wasn’t long ago that there was virtually no existing water and sewerage infrastructure in Melbourne’s outer north. It’s staggering to think of how far the area has come and how much further it will go in the next few years.”

New booster pump station improves Leeman water supply

A$2.7 million project to improve the reliability of the water supply in the Western Australian town of Leeman has been completed, with the replacement of an old elevated water tank with a new booster pump station.

Irrigation equipment works hard, so it needs a hard-working engine. Meet Hatz Diesel’s compact and all new H-50 Series. You know irrigation, we know diesel engines

• Up to 90 kg lighter than other engines in the power range

• Long engine life and premium components

• 500-hour maintenance interval

• 18.4 kW to 64 kW*

• Unsurpassed fuel efficiency

*(intermittent loading / ISO 3046-1)

POWER

The project is part of the Western Australian Government’s $35.2 million investment in 2019-20 for water projects in the Mid West region.

Work began in September 2018 to replace an aging elevated water tank, built around five decades ago, with a modern booster pump station.

The new booster pump station was constructed at the existing tank site north of Vivian Street on Indian Ocean Drive, and pumps water directly from the Mount Peron ground level tank to the local community.

The new pump station has provided the dual benefit of improved water pressure and reliability of water supply to the town.

Leeman is supplied water as part of the Leeman-Greenhead Scheme, which provides water to around 900 households and businesses in Leeman and surrounding areas.

The project was completed on time, with the pump station successfully

connected to the town’s water supply and the old tank taken offline in June 2019.

Work was completed by Guidera O’Connor, with three Western Australian subcontractors and suppliers also involved, including K&K Electrical, D & Z Constructions and SANDERS Demolition.

Western Australian Water Minister, Dave Kelly, said that Leeman is just one of the many towns across regional Western Australia which will benefit from the development and upgrade of essential water and wastewater infrastructure in 2019-20.

“Last financial year, the McGowan Government, through the Water Corporation, invested $25.9 million in water projects in the Mid-West region and that number will jump to $35.2 million this financial year,” Mr Kelly said.

“I would like to thank the local Leeman community for their cooperation during this important work.”

NEW WAVE ENERGY CONVERTER TO BE TRIALLED IN TASMANIA

The Australian Renewable Energy Agency (ARENA) has announced $4 million in funding to install a pilotscale wave energy converter off the coast of King Island, Tasmania.

The $12.3 million project by Wave Swell Energy will involve the design, construction, installation and operation of the UniWave 200, a 200 kW wave energy device off the coast of King Island.

The project will also be integrated with the King Island microgrid operated by Hydro Tasmania, which received $6 million in ARENA funding in 2011 to demonstrate the integration of several renewable resources and energy management technologies.

The device will be partially submerged as it sits on the seabed and has an opening on one side to allow the movement of the waves in and out of the chamber.

Water rises and falls inside the chamber, causing the pressure of the air trapped above to change between negative and positive pressure. The pressure fluctuations force the air to pass through the turbine at the top of the chamber, generating electricity.

ARENA CEO, Darren Miller, said the project will offer additional insights into combining wind, solar and wave energy.

“Wave energy has the potential to be integrated into microgrids, particularly on island locations with limited space, to reduce the need for significant battery storage due to the relative predictability and consistency of wave energy,” Mr Miller said.

“The tidal and wave sector in Australia is still in the early demonstration phase. Wave Swell’s unique approach to wave energy will gain valuable knowledge and help to see whether this is a viable option for generating renewable energy.”

Wave Swell Energy CEO, Dr Tom Denniss, said Wave Swell Energy is extremely pleased to have such a substantial component of the UniWave 200 King Island Project funded by ARENA.

“The project, aimed at demonstrating the commercial viability of the technology, is expected to be the first of many wave energy projects utilising this unique worldleading intellectual property. ARENA’s role in the King Island project represents a vital component of the ultimate commercialisation of the technology,” Dr Denniss said.

How to

THE LIFECYCLE COST OF YOUR PUMP MAXIMISE

When procuring a pump, upfront cost is often a major consideration in the decision-making process. However, according to a report issued by the Victorian Government, the initial cost accounts for less than ten per cent of the lifecycle cost, with energy and maintenance making up the bulk of these costs at between 50 and 95 per cent. Therefore, it is important to consider the long-term costs when selecting a pump to get the most cost-effective solution. Here, we look at what factors can influence and maximise the lifecycle cost of your pump.

While there are inevitable costs that are hard to control such as environmental, disposal and installation costs, end users can realise long-term savings with reduced maintenance, energy costs and downtime.

Selecting a pump: quality over cost

One important choice when selecting a pump that will influence its lifecycle costs is the quality of the equipment. A quality, reliable, well-built pump will likely have a lower lifecycle cost than a cheaper, lightweight pump.

Going for a cheaper option may result in a lesser quality product, especially if the materials selected are not suitable for the application. If this is the case, lifecycle costs can quickly increase as there is a higher chance of premature failure or unexpected servicing and replacement costs.

Along with materials, a high-quality product will have gone through rigorous testing to ensure it will run reliably and will be defect-free at the time of purchase.

Another area where quality can be realised is through the level of customer service you receive from the manufacturer. A manufacturer with top quality service will be able to provide prompt technical support to help troubleshoot any problems so that minimal downtime is experienced and that the pump is back to operating efficiently as soon as possible.

Companies with quality customer service will also be able to provide an expert opinion when selecting a pump to ensure it will be the best fit for your application so you can realise longterm cost savings.

Getting the right size pump

Selecting a correctly sized pump is imperative to reduce lifecycle costs. While it might be tempting to get a smaller pump to reduce costs or a larger pump to account for possible higher pumping requirements, these will ultimately result in higher costs in the long term.

An undersized pump will result in reduced water efficiency, while an oversized pump will have a higher installation cost, as well as higher energy usage and wear rate, so more frequent maintenance will be required.

Therefore, selecting a pump that is correctly sized to meet your exact needs will ensure the best energy efficiency and least energy wastage, and will have optimal lifespan and reliability.

Maximising energy efficiency

For applications such as irrigation where variable speed and flow rates may be needed, investing in a pump with a variable frequency drive (VFD) will help reduce lifecycle costs.

VFDs can be programmed to run the pumps at a certain speed and flow rate for different connected zones so that it is always running to its best efficiency point (BEP).

While a VFD will increase the initial cost of the pump, if the pump is not running to its BEP, it will experience increased wear and require more frequent maintenance and parts replacement, and have high energy consumption.

Quality and reliability at the heart of Franklin Electric

Malcolm Eyre, Managing Director at Franklin Electric, said the company understands its customers need for products that are durable and long lasting to ensure optimal lifecycle costs.

“Nothing less than having the highest quality products and service are acceptable for our customers, because anything else is too costly.

Leading the industry in service standards

HERE COMES THE STORY OF THE SHURRICANE

Ebara has rethought the hydraulic design used in multistage pumps. Utilising the latest in computational fluid dynamics and design, followed by rigorous testing, Ebara has developed a unique impeller design that offers solutions and value to the customer – the Shurricane.

The imbalance of forces acting on the front and rear shrouds of a conventional impeller results in axial thrust. This thrust load is compounding in multistage pumps, and has to be allowed for in the pump design.

For pumps with conventional impellers, the existing solutions include having a thrust bearing built in the pump, or to use a special motor fitted with a larger thrust bearing. Both are costly and can be complicated. Another solution has been to simply have a smaller diameter back shroud to reduce the thrust.

Ebara has rethought the hydraulic design used in multistage pumps. Utilising the latest in computational fluid dynamics and design, followed by rigorous testing, Ebara has developed a unique impeller design that offers solutions and value to the customer.

The optimised shape of the Shurricane maintains high efficiencies and very significantly reduces the axial thrust –meaning that any standard IEC motor can be used and bearing life is improved.

Built like a Katana

A Katana is a traditional Japanese product manufactured with care and precision. Only years of experience can give the necessary capacity to build a masterpiece.

This is what Ebara does with its pumps. The result of over 100 years of Japanese experience in pump design and manufacturing, their pumps offer high-quality performance, reliability, and cutting-edge technology.

Ebara’s vertical multistage pumps are manufactured in Italy to the highest standards of quality, and achieve reliable operating performance by means of

strict technical evaluation criteria and control programs that involve the whole manufacturing process.

Suitable for a range of applications

The range of Ebara vertical multistage pumps are suitable for a wide range of applications, in the industrial, commercial and agricultural fields. They can be used at water treatment plants (for reverse osmosis and filtration), for the pumping of hot or cold water for HVAC systems, for the pumping or boosting of water in general, and in boiler feed, irrigation and fire fighting systems.

The pumps can be coupled with any motor, anywhere. Optional materials are part of the unique hydraulic design, and there are optional connections for customers to consider.

THE PIONEERING TECHNOLOGY

CUTTING CLEANING TIME IN HALF

Parts Cleaning Technology is cutting the cleaning time in half for various industries including automotive, marine, manufacturing, aviation and more.

In any industry, the faster you can move projects through to completion, the better. Having said that, safety is always the priority. Celebrating its centennial year this year, NCH knows more than anyone that safety comes first.

By adopting the R&D best practice for any given product, NCH Torrent 500 Parts Cleaner technology, cuts service time by up to half, minimising safety hazards at the same time. This has resulted in reduced labour costs and delighted customers.

The Torrent system is a high pressure, waterbased, parts washing solution that not only improves efficiency, and maintains workplace safety, it reduces the environmental impact. In addition to workshops and manufacturers, the technology benefits service centres, construction, transportation and mining industries to

achieve the same results. No matter the application, they all need a solution that is quick, easy to use and safe.

Because of the unique combination of pressure, temperature and chemistry, the system cleans most parts in just one minute, five times faster than automatic machines. While the technology is nothing short of revolutionary, each industry agrees that Torrent is a game-changer.

“We calibrate the cleaning solution for the specific needs of every client,” said Reno Mythillos of NCH.

“We’re proud to have brought this system to the various industries that makes a noticeable difference in their workplace,” said Reno. “On our regular service visits to maintain equipment and fluids, we get to see how they are using the Torrent, and it is always a perfect fit for their needs.”

While traditional machines use oil-based chemicals that are great at separating grease from parts, the solvents are hazardous in the workplace and on employees. NCH said the Torrent uses a combination of heat, water, a powerful detergent and pressure to achieve better results. The equipment’s detergent has a combination of corrosion inhibitors that result in a much more effective clean.

Ideally positioned adjacent to North Fremantle’s famous Leighton Beach, the prized real estate addition is only 15 kilometres from the Perth CBD and just 5.5 kilometres from the heart of cosmopolitan Fremantle.

Viega Propress was used for hot and cold water distribution to service all 249 apartments in sizes varying from DN15100mm. Hot water delivery was supplied from two central energy plants located on the roof of the new buildings. Viega Propress Gas was also used on the copper installation for gas supply to each of the luxury apartments.

Pipeline Hydraulics was tasked with carrying out all plumbing works associated with the development’s sewage, stormwater, water supply and gas supply.

The company’s Operations Manager, Mark Sadler, said that the Viega Propress system provided the perfect alternative to traditional plumbing solutions.

“Originally the tender docs called for all copper work to be welded or brazed, but we tried to steer clear of that so we wouldn’t have to organise hot works permits,” he explained.

“So, we looked for an alternative and Viega was there to help. Using their products meant we didn’t have to drag a big oxy set around and then spend time actually welding each individual fitting. It saved so much time. I reckon we got the job done three times faster than had we welded. It’s the first time we’ve used Viega. We’ll definitely use it down the track on other projects.”

PRACTICALITY AND FUNCTIONALITY

Providing superb motor management

The introduction of our new SSW900, low voltage soft starter series continues to build on our broad motor starter range offered in Australia.

Torque control through the starting, processing and stopping functions remains the core to any good plant operation(s), and the product features and functionality of all WEG variable speed drives (VSD) and soft starters are designed to deliver just that.

A risk of any product diversity is complexity in programming with the subsequent difficulties for those providing general support services, but we have that covered.

Every VSD and soft starter from WEG is designed and manufactured in-house, and comes with a common and universal approach to parameters, setup and complex programming functions.

Low and high voltage soft starters covering outputs from 2.2 to 5740kW ultimately share the same manual. Similarly our VSD range covers drives from smallest single phase units up to state of the art 11kV systems, which share a majority of parameters and logic.

Maximising the investment in the training of operators and technicians is made profoundly easier by this strategic approach to product design.

Speed in commissioning and during the fine tuning of processes underpins an overall lower cost to the customer, and having a consistent platform across all our motor controllers makes this a reality.

The new SSW900 low voltage soft starter is the latest addition to our range. While keeping with the consistent approach, the SSW900 comes with additional functionality and contemporary features and will be taking over from the SSW06 series, which has been a product of choice for over 12 years.

This product fits seamlessly into our portfolio, with no disruption to our customers, distributors or service network, bringing functionality and practicality to the idea of "thinking globally, acting locally".

FLEXIBORE CHOSEN FOR ADELAIDE IRRIGATION PROJECT

In addition to adding 12 gigalitres of reclaimed water to the Northern Adelaide Plains, the Northern Adelaide Irrigation Scheme (NAIS), with a combined $155.6 million in funds contributed from the State and Federal Governments, will create 3,700 jobs and add a projected $500 million per year to South Australia’s economy.

With operations at Holden’s Elizabeth motor plant ceased, the people of North Adelaide who were hit the hardest will benefit most from jobs created during the construction of NAIS. This scheme will see new water treatment facilities built to increase the production of recycled irrigation water by 60 per cent, which will be suitable for food production. The benefits, once the project is completed, will be far-reaching.

NAIS has paved a clear path to get really high value crops from the fertile Northern Adelaide Plains to overseas markets. Demand in countries such as China, Japan and Korea – where Australian produce is appreciated for its freshness and quality – has been growing. Furthermore, some water will also be unlocked for the Barossa, where premium food and wine harvesting is one of South Australia’s economic pillars.

The water will be pumped into large storage dams from ten bores located around the Bolivar precinct, all using submersible pumps and Australian made Flexibore.

Providing a technical solution

Francois Steverlynck, the Managing Director of Crusader Hose, the manufacturers of Flexibore, said, “This is a flagship project for our company. We have worked closely with Leed Valoriza, the major contractor, to deliver a very technical solution in rapid time.”

Sam Doolette, project engineer at Leed Valoriza, was particularly impressed with the service and support he received from Crusader Hose.

“We had Francois come over from Melbourne to assist with the submersible bore pump installation,” said Mr Doolette.

“We were very pleased to see how easy the pumps could be installed using Flexibore and after completing the first one, we scheduled the rest to be installed at two per day. Final commissioning is planned for the end of September, and by ramping up, we will be able to supply consistent water flow that is completely independent of how much rain we get, or how full the Murray River is. This will provide certainty, as well as higher quality water at the same time.”

Supporting local industry

Business SA has long been proponents of supporting local industry, including Australian manufacturers.

Mr Doolette was well aware of the benefits of keeping jobs local.

“When we buy Australian made flexible risers, we not only increase local capabilities, but we also keep funds within the country. The multiplier benefit can be more than five times the benefits to local industry,” Mr Doolette said.

Flexibore was developed in Australia in 1991 in order to meet the market needs for a riser pipe that could be corrosion-free, never clog up due to iron bacteria, and also be easy to install. Through continuous improvement and innovation, Crusader Hose has grown to become the supplier of choice for mining, irrigation and government projects needing to pump groundwater.

“Australia has a clean and green image, cultivated over years of managing our resources responsibly. We also have a capable manufacturing industry, brought about by hard work and investments in education. It is wonderful when we all work smartly together to deliver projects such as NAIS as this will continue to benefit generations of Australians,” Mr Steverlynck said.

VOLVO PENTA: THE HEART THAT NEVER STOPS

Volvo Penta’s engine range is characterised by high performance, reliability, fuel efficiency and low emission levels. Built to be versatile, their low weight, compact designs, easy installation and optional equipment packages make them perfect for numerous machine and equipment applications in a variety of industries.

As part of the Volvo Group, Volvo Penta is a premium supplier for engines for the pumping industry.

“We continuously work towards sustainable solutions and provide both OEMs and operators with stateof-the-art engines and technology based on over 100 years of engineering experience. Our engines power agricultural applications all over the world – contributing to the overall productivity of the operations through excellent performance and fuel efficiency,” Bjorn Saljo, Head of Volvo Penta Oceania said.

Aside from various pump applications (fire, irrigation, dewatering), Volvo Penta engines can be found in a wide variety of industrial applications including power generation, materials handling, rock crushing, underground mining equipment, ventilation machines, tractors, forestry machines, and tomato and cane harvesters, just to name a few. Some of the world’s largest equipment manufacturers turn to Volvo Penta for their engine requirements.

“Our industrial engines are all engineered to be part of a common platform. This means a future-proof engine range with engine interfaces and range architecture that match the different emission stages. The platform commonality also facilitates service and parts availability,” Bjorn said.

Cost of ownership

As part of the Volvo Group, Volvo Penta is at the forefront of the engine industry and is always looking for ways to reduce total cost of ownership while maintaining the reliability and the longevity of its engines.

To maximise uptime, most Volvo Penta Industrial engines can operate for 1,000 hours between service intervals. Productivity can be increased and uptime maximised by using the corresponding service protocol, an approved Volvo Penta Oil Analysis and genuine Volvo Penta oil filters with the appropriate oil and fuel quality.

The old and the new

With 30-year-old pump engines still in operation on farms throughout the country with well over 30,000 hours on the meter, it’s easy to see why farmers still look to Volvo Penta for their pumping requirements.

Ben Watson is from Allabah Pastoral Company, a large farm that produces cotton and raises livestock. Every day, Volvo Penta engines deliver indispensable work horses to Allabah’s pumps, running water with high reliability and uptime.

“We rely heavily on Volvo Penta to harvest water when it’s available,” he said.

“If you head down there some four or five kilometres in the pouring rain and are not able to hit the start button, it can be detrimental. With Volvo Penta on board, it’s just been awesome. It’s really changed the reliability and fuel efficiency too.”

David Phelps at Havana Farming also depends on diesel power to guarantee water is pumped to his vast plantation fields. The extended service intervals of Volvo Penta engines mean Havana Farming is cost efficient and always dependable.

“Volvo Penta is where we went 20-25 years ago. They’ve been very reliable motors, and now that we’re in an upgrading situation, we are just sticking with Volvo; I don’t see any reason to change. They were ahead of their time 20 years ago, as the new ones are now; they’re at the forefront too. Like any business, you’ve got to keep it humming, otherwise things can go backwards pretty quick,” he said.

Reliable engine, reliable network

MOTOR STARTING for optimum performance

It is often believed that the start current of a motor under full voltage conditions depends on the driven load, but this is incorrect.

The start current of the motor depends on the motor design, rotor speed and stator voltage from zero speed until full speed is reached. The load only influences the time taken for the motor to reach full speed. The current/ speed curve of the motor is independent of all external influences other than stator voltage.

Full voltage starting: DOL starters

The DOL starter causes a current transition from zero to locked rotor current (LRC) at the instant of contactor closure. It also causes a torque transient from zero to locked rotor torque (LRT) at the instant of contactor closure, resulting in a severe mechanical shock to the motor drive system and the machine.

Reduced voltage starters

The following four starter types are examples of reduced voltage starting which are used extensively and, in many areas, is mandatory. However, many installations would suffer fewer disturbances if a full voltage starter replaced a poorly applied reduced voltage starting system. The reduced voltage starter must be able to accelerate the motor to almost full speed before stepping to full voltage, or it risks a current step that can be very close to LRC. Therefore, start time and start voltage must be correctly set.

1. Primary resistance starters

Using resistors, connected in series with each phase, between the isolation contactor and the motor, limits the start current and torque. If the resistors are too high for the start voltage, there will be insufficient torque to accelerate the motor to full speed. In this case, the step to full voltage will result in a high current and high torque step. Several stages of resistance can be used to control the current and torque more accurately, minimising the magnitude of the current and torque steps.

2. Autotransformer starters

An autotransformer reduces the voltage during the start period. If the start voltage is too low, or the start time incorrectly set, the transition to full voltage will occur with the motor at less than full speed, resulting in a high current and high torque step. Autotransformer starters are usually rated for infrequent starting duties.

3. Star-delta starters

The star-delta starter is the most common reduced voltage starter used in industry because of its low cost. The motor is initially connected in star configuration and then, after a pre-set time, the motor is disconnected from the supply and reconnected in delta configuration. If there is insufficient torque available in star configuration to accelerate the load to full speed, a high starting torque motor such as a double cage motor should be used. If the motor does not reach full speed in star, the transition from star to delta configuration will result in a high current and high torque step, defeating the purpose of reduced voltage starting.

4. Solid-state soft starters

The solid-state soft starter controls the voltage applied to the motor through impedance in series with each phase connected to the motor. It uses solid-state AC switches with a very low power dissipation compared to traditional primary resistors, and is controllable to give a motor voltage from zero to full line voltage without any steps or transients.

It is possible to correctly apply and engineer electromechanical reduced voltage starters so the torque and current magnitudes and transients are reduced to acceptable levels. Reduced voltage starting reduces the electrical interference caused by motor starting and reduces mechanical damage caused by torque transients and steps. To achieve these objectives, the motor and starter must be correctly selected and commissioned for optimum performance.

ENERGY ELECTRIFYING INDUSTRY – NEW

The Australian manufacturing industry is at a crossroads.

Transforming the materials we dig up or grow into the products we use every day requires enormous amounts of heat, and rising electricity costs and inefficient processes means many businesses have seen their gas and electricity bills double over the last two years. A report from Beyond Zero Emissions shows there are opportunities for manufacturers to reduce costs by generating heat through the smart use of renewable electricity, with heat pumps one technology that they can take advantage of.

From fossil fuels to electricity

Every year in Australia, burning fossil fuels for industrial heat processes produces 42 million tonnes of carbon dioxide, or eight per cent of the country’s greenhouse gas emissions –as much as Australia’s entire car fleet and more than the state of South Australia. If we look at these numbers globally, the contribution of process heat is higher – about 12 per cent of all emissions.

While fossil fuels have powered industry since the industrial revolution, a new low-carbon industrial transformation is possible and could transform existing industries.

The report, Electrifying Industry, shows how electrification, powered by renewable energy, could not only eliminate eight per cent of Australia’s emissions and revive the entire manufacturing sector, but also reduce greenhouse gas emissions.

Electricity is remarkably versatile and has no practical temperature limit, meaning it can power any industrial heat process, from cooking a can of beans to melting 100 tonnes of iron.

By adopting a range of heat technologies – both old and new – industry can make things in a smarter way and can double the efficiency of many industrial processes, saving money in the process.

Australia’s renewable advantage

With Australia’s abundant renewable resources, there is the additional opportunity to develop a clean, efficient manufacturing sector, adapted to the needs of the 21st century. It is an affordable and reliable source of energy, with some manufacturers already taking hold of this opportunity, paying 20-50 per cent less for electricity. They have done this by either building their own renewable installations or agreeing to contracts for renewable energy supply.

By electrifying all industrial processes, six to eight per cent of Australia’s greenhouse gas emissions can be reduced.

It also creates an opportunity to use electrical heating technology such as heat pumps, opening the industry up to more efficient technologies to save money.

EFFICIENCY OPPORTUNITIES FOR IMPROVING

An opportunity for heat pumps

Heat pumps use electricity to make hot water, air or steam. They are able to produce three to seven times more thermal energy compared to the amount of electricity they use, leading to efficiency of 300-700 per cent. They also provide an opportunity for manufacturers to reuse sources of energy that would otherwise be wasted, such as heat expelled by refrigeration systems.

The past decade has seen high temperature industrial heat pump technology develop rapidly and there are options available now that are able to reach temperatures up to 140160°C – hot enough for many industrial processes, including for food, chemical and paper applications.

In particular, there is great potential for heat pumps to be used as an alternative to inefficient centralised gas boiler systems that are found in most factories.

The report found that while heat pumps have a high upfront cost, overall, the energy efficiencies provided by heat pumps means that their installation costs can often be paid back within two years.

It will cost around $500-1000 per kilowatt of heating capacity for a heat pump system where the pumps are below 500kW, with 1+MW systems costing around $275500 per kilowatt. Depending on various site specific factors,

installation cost can add an additional 25-100 per cent onto the purchase price. This makes the upfront costs of a heat pump system two to three times more expensive than that of an equivalent gas boiler.

However, heat pumps have lower running costs, so it will pay itself off in only a few years. This is because the heating capacity of these pumps is lower as distribution loss is minimised. There are further cost savings if the pumps are replacing costly steam distribution systems as well as the central gas boiler; and if installed in a modular fashion, plant owners only need to replace the most inefficient parts of the boiler system, rather than shutting down and replacing the entire system at once.

A high coefficient of performance (COP)

When looking at the ratio between the electrical energy used by a heat pump and the heat they produce (their COP). Heat pumps are highly efficient – a pump which is 400 per cent efficient has a COP of four, and some which are used for both heating and cooling can reach a combined COP as high as ten. This means that if a pump has a COP level of ten, there are ten units of heating/cooling for each unit of electricity.

Compared to traditional gas boiler systems – that rarely achieve efficiencies above 80 per cent, and more often less

than 50 per cent due to heat loss – heat pumps have a greater advantage as they can reuse heat that would otherwise be lost, extracting almost 100 per cent of thermal energy in exhausted heat. This is because heat pumps can extract latent heat by condensing water vapour.

Uses for heat pumps in manufacturing:

• Replace all or part of boiler steam systems

• Use in conjugation with mechanical vapour recompression to produce steam

• Achieve higher temperature uplift with greater efficiency when installing heat pumps in a series

• Use in conjugation with heat storage to reuse excess heat at a later time

• Heat materials to a target temperature while another system does the rest of the work

• For processes where lower temperatures are required compared to the main process

• Replace end-sections of long heat distribution pipes with high heat losses

Heat pumps in Australia

Unlike other parts of the world such as Japan and South Korea – and to a lesser extent Europe – there are very few industrial heat pumps installed in Australia, despite the potential they present to replace gas and fossil fuels in processes requiring hot air, water or steam up to 160°C. This means they can be used to supply a majority of the heat requirements for processes in the food, paper, wood and textile industries; and displace one third of the energy used by chemical sectors to generate steam.

By replacing these systems with heat pumps, around 95GJ of fossil fuels used for industrial heat – around 15 per cent – would be eliminated. If these heat pumps are powered by renewable energy, nearly five million tonnes of greenhouse gas emissions would be eliminated.

One of the biggest barriers currently stopping the wider uptake of heat pumps in Australian manufacturing is a lack of local expertise and awareness within the industry. Such barriers have been overcome in other countries though government support such as investment incentives, demonstration projects and information provision. There is scope for this moving into the future as studies in other sectors, including HVAC and building services, are being undertaken as to their feasibility.

IMPROVES PUMP EFFICIENCY AT MELBOURNE WATER TREATMENT PLANT

Winneke treatment plant, located in the hills north east of Melbourne, was commissioned in the early 1980s to provide a treated water source to meet the growing needs of Melbourne’s developing northern and western suburbs. The plant sources water from Sugarloaf Reservoir, which is harvested from the Yarra River and Maroondah Reservoir in the east. Once treated, the high-quality water is gravity fed via a 2.1m-diameter transfer main into the transfer system network where it’s used to supplement other supplies. This source of water is especially useful during years of low rainfall and can provide stress relief to Melbourne’s main storages and catchments.

The source water for the treatment process is pumped from the Sugarloaf Reservoir directly into the head of the plant via the reservoir pumping station. The station was commissioned with three large TKL horizontal split casing centrifugal pumps coupled to 3.2MW high voltage motors operated via slip recovery high voltage drives. In 2010, the 3.2MW motors and drives were replaced with 1.6MW motors and new technology including variable speed drives (VSDs).

into the pump station’s existing programmable logic controller (PLC). Many of the solutions were “black boxes” with the intellectual property retained by the vendor. Vendor solutions presented the additional problem that the operation of their solution could not be guaranteed at all times, with vendors often unable to provide support 24 hours a day, seven days a week. It was these factors that led Melbourne Water to consider implementing its own AI solution.

There were two drivers for this upgrade. Firstly, the motors and drives were at end of life, and secondly, the original design was not optimal for providing efficient pumping when the Sugarloaf Reservoir was near full.

As part of the upgrade, an additional three 375kW TKL horizontal split casing pumps were also installed. These were to provide more flexible operation of the system and efficiency when levels were high at Sugarloaf Reservoir.

Collecting data for more efficient pumping

From 2010, Melbourne Water began to analyse data collected from its supervisory control and data acquisition (SCADA) system to measure the efficiency of the pumps. In 2016, the results showed that the new 1.6MW motors and VSDs were more efficient than those they had replaced. However, it was thought that improvements in pump selection and speed, and utilising all six pump sets could yield even greater efficiencies.

In late 2016, Melbourne Water started on a journey of automation and data analytics, incorporating machine learning (ML) and artificial intelligence (AI) into its operations. One of the first AI projects was targeted at the operation of Sugarloaf Reservoir pump station. The aim of the project was to automate the selection of pumps and the speed of each to optimise energy consumption. An added advantage of the project was the automatic bumpless transfer of failed pumps to standby pumps during plant operation. While this type of automation is common, it had never been implemented at this site.

Initially, options for the AI solution were provided by external vendors. These were found to be costly, with largely unknown success rates. They were also difficult to integrate

In early 2017, a senior data analyst extracted the data collected over the previous seven years from Melbourne Water OSIsoft PI historian using the Python programming language and other software tools. The data was arranged in an array with variables comprising of the Sugarloaf Reservoir level (suction head), plant throughput (flow rate), pump availability and pump speed. From this array it was a relatively easy task to use Python to search the data for the most efficient combination of running pumps and speed to deliver the required flow rate at current reservoir levels. The output of the Python program is kWh per megalitre and it is calculated on every flow setpoint change initiated via the operations team and when any of the other variables, such as reservoir level or pump availability change.

Integrating the custom solution with existing systems

The greatest challenges of the project were the integration of the Python solution into the existing PLC and the change management aspects for the operational teams involved. The solution for the PLC integration ended up being quite simple. A Python library is freely available that allows direct read/write of values directly into the PLC processor memory area. This was used for the main transfer of data between the two systems. The PLC writes real-time data into a set of memory registers for the Python program to read. These include all values that are required for the program to operate and the flow rate setpoint, pump availability and reservoir level. Once the Python program assesses that a change is required, it writes values into a separate set of registers in the same area for the PLC to act on. These included the required pumps to run and the speed with which they are to run.

The PLC continues to provide the base control of the pumps and does not accept erroneous values from Python. Any pump failures or faults are dealt with by the PLC; pumps are shutdown on critical alarms, and warnings are provided via SCADA for non-critical events. In the event a pump is shut down by the PLC due to a fault, the updated pump status is written to PLC memory where the Python program reads it and another pump (the next most efficient) is selected for operation by the program. This cycle continues while the control system mode is selected to “optimise”.

The health of the connection between the Python optimiser and the PLC is controlled via a counter installed in Python system. If the PLC detects that the Python optimiser counter is not increasing, it alarms on SCADA and reverts the station to normal automatic control. The entire Python optimiser runs on a dedicated industrial PC that is only connected to the local control system network. Access from outside of the site is not possible and as such we have a high degree of protection against cyberattack.

Making operations more efficient

Since the installation was completed in early 2018, the optimiser has reduced power consumption for the pump station by approximately 20 per cent, saving $200,000 per annum. This saving has continued into 2019 and monitoring continues via a dashboard created in the OSIsoft PI historian. The monitoring provides near realtime trends of the totalised power versus totalised flow for the year in comparison with the best and worst examples recorded since 2010 for the same values. Further analysis shows that the greatest benefits are achieved by running multiple pumps when reservoir levels are high and less pumps as levels drops. This contrasts with the traditional approach of using just one pump.

When first implemented there was some skepticism that running five pumps could be more efficient than operating one pump to deliver the same volume. However, those that understand pump curves appreciate that efficiency is determined by the design of the impeller among other things. In this case the original three pumps were designed to be efficient at low suction pressures due to the belief that the reservoir would be low most of the time. This turned out not to be the case and the three new pumps were selected on their ability to operate efficiently at higher reservoir levels. Overall, it was a combination of these pumps and an assessment of the optimum flow rates and suction pressure that delivered the most efficient method of operation.

Melbourne Water continues to roll out other AI solutions across its business to help it improve the efficiency of its operations.

The Water Industry Operators Association of Australia (WIOA) Operator of the Year award is the most prestigious award presented to operations staff in the South Australian water industry annually, recognising excellent performance, initiative and all-round attention to detail. In 2018, the SA Operator of the Year was awarded to Brad Alcorn, Senior Construction and Maintenance Worker for SA Water in Leigh Creek.

New career opportunities

Following the closure of Flinders Power's operation in Leigh Creek, Mr Alcorn was one of the many people left looking for work, but a local opening advertised by SA Water presented him with the chance to keep his family part of the Leigh Creek community and forge a new career in the water industry.

“Previously working as a plumber, I’ve always had a keen interest in the water and wastewater industries and getting hands-on in my work,” Mr Alcorn said.

“Having developed a love for Leigh Creek after 16 years in

my previous role and having no interest in leaving when the management of the town was transferred over from Flinders Power, I luckily jumped at the opportunity to apply for an advertised position at SA Water and remain in the region I love.

“I’m also extremely fortunate that I get to work alongside my son Joel, who helps service the water and wastewater network in Leigh Creek.”

Mr Alcorn said taking on the role at SA Water has been rewarding, allowing him to undertake formal training and develop new skills.

“On top of my existing knowledge of the local water network developed over the years, I also undertook a training course in Geelong to become an accredited wastewater operator. As a result, I have taken on the additional responsibility of managing the Leigh Creek Wastewater Treatment Plant.

“My son Joel and I also undertook formal training to receive our Certificate III in Water Operations, which has been an extremely fun and rewarding experience to learn new skills even after all these years.”

Recognised by the industry

Mr Alcorn had been with SA Water for only two years when his work was recognised by WIOA.

“I’m extremely proud to be recognised for this award, and the important role the work we do plays for our customers in Leigh Creek and surrounding regions. I wasn’t expecting to pick up the award, so being able to be recognised for my work has been a real feather in my cap and I look forward to furthering my professional career in the industry.”

Mr Alcorn was presented with the award at WIOA's South Australian Wastewater Interest Day in Mount Barker, and as part of the prize, joined other WIOA award winners from across the country on a study trip to visit wastewater treatment plants in New Zealand in May this year.

“I really enjoyed the trip to New Zealand as part of this award, and found it extremely interesting to see how their water and wastewater plants operate in comparison to back home,” Mr Alcorn said.

“I found it encouraging to see a lot of similarities in how they run, which demonstrates that we are all operating at a similarly high level.

“The largest difference I noticed was how they source water for their customers from sites like glaciers, given a large amount of drinking water in South Australia is treated drinking supply from the River Murray, or in Leigh Creek from a series of nearby bores.”

SA Water Manager of Customer Field Services, Colin Bell, said the award is a testament to Mr Alcorn's passion for the work he does and the local communities he serves.

"Brad is a skilled and highly-valued member of our team, and this recognition shows the positive impact he is making to both the business and customers in the Leigh Creek area," Mr Bell said.

A diverse and rewarding role

Mr Alcorn said his current role as Senior Construction and Maintenance Worker is diverse and involves monitoring the water and wastewater networks in Leigh Creek, including fielding customer enquiries, and assessing water meter and water main leaks and repairs.

“A typical day involves starting with manual checks of the wastewater lagoons to ensure the aerators and flow levels are operating as normal for our customers before doing any required network operations tasks or repairs to maintain the reliability of the network,” Mr Alcorn said.

Mr Alcorn also helps to maintain a small number of smart water meters installed in the small townships of Copley and Lyndhurst, which helps SA Water best manage the water network in these areas.

This has presented him with a challenge as he was previously unfamiliar with these areas, but he has embraced it and is enjoying this part of his role.

“The largest challenge I have faced so far with SA Water has been learning how to manage the water networks for our customers in Copley and Lyndhurst, given my previous experience in the water network was solely in Leigh Creek,” Mr Alcorn said.

“It has taken a while to learn and understand the ins and outs of the intricate network which changed to SA Water management in 2018, but I have embraced the challenge and enjoyed maintaining the network for more than 70 additional customers in the two townships.

“I really enjoy getting to ply my trade everyday knowing that the work we are doing is delivering essential services to the local region, and is important to the health and well-being of the wider community.

“As an added bonus, getting to spend my career alongside my son as the two-person team in Leigh Creek and seeing him develop over the years is also very rewarding.”

The pump industry relies on expertise from a large and varied range of specialists, from experts in particular pump types to those with an intimate understanding of pump reliability; and from researchers who delve into the particulars of pump curves to experts in pump efficiency. To draw upon the wealth of expert knowledge the Australian pump industry has to offer, Pump Industry has established a panel of experts to answer all your pumping questions.

This edition of Ask an Expert will look at technological advances for progressive cavity pumps with quick and easy maintenance solutions.

Q: What steps are progressive cavity pump manufacturers taking to make their product easier to maintain?

A: Occasionally, after a progressive cavity (PC) pump has been in use for a while, maintenance work will need to be carried out. Various PC pump manufacturers are expanding their portfolios with easy-to-use maintenance concepts to save customers time and money when working on the pumps.

Standard PC pumps

The rotating parts of a pump can eventually wear down and need to either be exchanged or readjusted. New technology from manufactures offers quicker and easier access to the rotor and stator unit and even ways to readjust them for increased flow. Along with the rotor end of the pump, there are solutions for working on the drive side pump components to remove the entire rotating unit without having to disassemble pipework, suction housing and/or other components.

PC pumps with a feed hopper

Pumps with feed hoppers present a special type of challenge. Not only do they convey viscous products with little flowability, but also maintenance on these pumps is time consuming and complicated due to valves and hoppers obstructing access to the pump.

To combat this issue, PC manufacturers have designed various ways to access drive side along with rotor side joints and parts. One solution is to make part of the casing movable so that seals and even the drive are quickly installed or removed on-site. With access to both the front and back areas of the pump, customers have two technologies at their disposal for exposing components for maintenance without having to disassemble pipework, valves or the feed hopper. This unimpeded access to the relevant pump parts simplifies all subsequent work on both pump ends.

Q: What benefits can customers experience/see with easy to maintain PC pumps?

A: Intelligent maintenance concepts reduce downtime and save time and costs.

• Significantly reduced maintenance costs: Easy access to rotating parts and joints without disassembling extra components, casing parts and/or pipework

• Preventive maintenance: Regular, easy and quick check-up of components

• Increased uptime: Proactive inspection and maintenance ensures trouble-free operation

These are just some of the ways PC manufacturers are looking to save you time and money.

The PIA’s Australian Pump Technical Handbook is a cornerstone text for the Australian pump industry and, in our opinion, a must have for anyone who deals with pumps on a regular basis. In this ongoing series, we feature abridged chapters from the classic book to showcase the various areas covered and to reacquaint readers with the technical aspects of pumps. In this issue, we look at efficient operations of pump systems.

With an increasing focus on the reduction of greenhouse gas emissions, Australian industry is endeavouring to reduce power consumption, including where plants are required to operate for long periods of time at high levels of demand.

Pumping equipment can be considered a significant consumer of power and the global industry has been endeavouring to design better products and more innovative systems to address this issue. In order to maximise energy efficiency in pumping systems, it is necessary to consider the

complete pumping system. This means from the initial source of the fluid, through the pump and its control system to where it is finally discharged.

Since system performance can also change with time, how the system is maintained can have an important bearing in the long-term efficiency of the total installation.

While there are a number of ways in which one can approach these issues, it can be looked at in five simple steps and provide guidelines on how practices can be applied to minimise energy consumption.

These steps include:

• Losses in pumps, both centrifugal and positive displacement

• Losses in systems and how these can be minimised

• Matching a pump to the system requirements

• Drive considerations – starting and speed control systems

• Lifecycle costs

The key to an efficient pumping system is to select the most appropriate pump for the specified application and operating conditions.

It is advised the user spend as much time as possible defining the conditions of service that a particular application will generate. If these are known, it is possible to provide users with a recommended solution that best meets the needs of the application.

Teamwork achieves the best outcome and a dialogue between the pump supplier and the pump user has generally led to better outcomes in plant design.

Pump efficiency

While the main focus of this section is on centrifugal pumps, similar considerations would apply to positive displacement pumps.

Positive displacement pumps are normally used for liquids with high viscosity, low flow and high pressure, or where an accurate flow rate is required for every pump revolution.

The efficiency of positive displacement pumps is dependent on a determination of internal friction and leakage losses. Friction losses in the system depend on the rate of flow, whether it is constant or pulsating, and the characteristics of the fluid being pumped.

Efficiency measurement for rotodynamic pumps

There are many different types of pumps on the market and, while just a small number of these are in common use, it is important to understand the significance of the performance information that the manufacturer supplies, which allows for the selection of the most suitable pump for an application.

Pump efficiency is measured by testing the product in controlled conditions with accurately calibrated instrumentation. In Australia, AS 2417-2001 is the standard by which rotodynamic pumps should be tested. However, the test data which measures flow, head, power absorbed and rotational speed is then used to calculate pump efficiency. Which grade of testing applies to the data would normally be shown on the performance curve and this implies the tolerance level that will apply to pump efficiency.

A summary of the tolerances on efficiency is provided in Table 1.

A pump is selected based on a nominated duty point, and the manufacturer's performance data should be used to select the pump as well as to determine the operating efficiency and power absorbed. The question becomes “how accurate is the performance data provided?”.

If a user wishes to have a higher level of accuracy for pump performance data, then it is prudent to deal with the manufacturer directly and obtain a performance guarantee based on an objective assessment of all the conditions of service and nominate either Grade 1 or Grade 2 tolerances.

However, it should be noted that most standard pumps (e.g. ISO 2858 end suction pumps) are selected based on published curves in catalogues. In such cases, the test standard allows for extra wide tolerances for flow, head and efficiency to be applied, and these are listed in Annex A at the rear of AS 2417-2001

Losses in rotodynamic pumps

While it is important to know the overall efficiency of a pump, it can also be helpful to understand what contributes to the inefficiency of the pump. Is it poor design? Is it poor manufacture? What can be done to get a better outcome? These are often questions that can best be answered by looking at the losses which occur inside a pump.

These fall into two basic categories:

1. Hydrodynamic losses – entry and exit shock losses, losses through the impeller, disk friction losses, leakage losses

2. Mechanical losses – friction in bearings and at the seal etc.

The relative significance of these two categories often relates to the pump design, the speed of operation and the duty the pump is selected to satisfy.

There is also a relationship between pump efficiency and specific speed.

Earlier work on rotodynamic pumps idicates that mechanical losses are relatively constant across the specific speed range, but the main variables are:

• Disk friction losses – high in pumps with low specific speeds. Radial impellers have a relatively large diameter and small width

• Leakage losses – higher in pumps with low specific speed, especially when seal ring clearances are increased to prevent galling in pumps with hard materials for casing and impeller

• Casing friction losses – these are higher at higher specific speeds and relate to the velocity over the internal surface of the casing. Friction losses are proportional to the velocity squared

Impeller trimming changes in performance (Part 1)

Impeller trimming means the reduction of the impeller diameter from maximum, usually to adjust the pump performance to a required duty point. Performance curves for centrifugal pumps usually detail the performance for a number of impeller diameters between a maximum and minimum allowable diameter. Several things can happen when the impeller vane diameter is reduced.

Changes in performance

Simply put, the greater the impeller reduction and the higher the specific speed of the impeller, the more the pump efficiency will decrease with impeller trimming. The change in pump performance with changes in impeller diameter can be predicted similarly to that with speed change utilising the affinity laws:

• Pump flow rate (Q) varies directly with the diameter (D) i.e. Q1/Q2 = D1/D2

• Pump head (H) varies with the square of the diameter (D) i.e. H1/H2 = (D1/D2)²

• Power absorbed varies with the cube of the diameter (D) i.e. P1/P2 = (D1/D2)³

These relationships (not laws) allow adjustment of the H-Q curve but there is a detrimental impact on efficiency especially for impeller reductions greater than ten per cent of maximum.

NPSHR

In general, impeller diameter reductions greater than five per cent to ten per cent of the maximum will increase the NPSHR (net positive suction head required) dependent on impeller specific speed.

S = rpm x √Q NPSHR¾

It can be seen in this equation that NPSHR should not change with changes in impeller diameter as long as flow and RPM remain constant. There is no factor in the S equation that relates to impeller diameter. Suction specific speed (S) remains constant, for any defined inlet geometry, as long as the field of flow into the impeller eye is not disrupted by events taking place downstream of the impeller inlet. When trimming impellers on pumps that are of a low specific speed (Ns <30 SI, 1500 US), tests have shown that there is little effect on NPSHR within the allowable impeller cut range. Beyond the allowable impeller cut range, recirculation between impeller discharge and the impeller inlet start to disrupt the inlet field of flow, increasing the NPSHR. More accurate information can be obtained from a complete performance chart with different impeller diameters detailed.
