President’s welcome

Dear PIA Members and Industry Colleagues,

Welcome to the winter edition of Pump Industry.

Winter in Australia may be milder than many other parts of the world, but a cold snap quickly reminds you that winter has arrived. We have seen extreme rainfall in New South Wales, with a month’s worth of rain falling in just one week, resulting in major � ooding. Meanwhile, Victoria, South Australia, and other states experienced cooler conditions, while all states had warmer-than-average daytime temperatures.

Since our last edition, as well as seasonal changes, there have been challenges and changes in the political environment in Australia. The federal election was held in May, with the Albanese government securing a second term. There will be changes that impact businesses moving forward as they implement their agenda and election commitments.

The re-elected government is making moves in the industrial relations space. Starting in 2027, non-compete clauses will be banned for workers earning under $175,000. This includes � xing wages and preventing sta� poaching. The government is committed to stopping the industrial umpire from altering rules regarding penalty rates for higher base pay. Several support policies will assist small businesses.

The other main event was the Reserve Bank of Australia’s (RBA) decision to cut interest rates in May. The economy is still expected to experience a weaker growth outlook, and the RBA anticipates an increase in unemployment, although this is considered low by historical standards. It brings some relief to households with further rate cuts expected later in the year.

US President Donald Trump’s tari� s have directly impacted Australian businesses. The latest information I have, as I write to you, is that the

baseline is 10 per cent on most imported goods. Steel and aluminium are being subjected to 25 per cent tari� s.

All the above matters bring about their own challenges to our economy and our businesses as we move through the next 12 months.

The committee held its most recent council meeting in May. I am pleased to announce that the committee has appointed Naomi Lincoln as the new Secretary-Treasurer. She has been in the industry for the past nine years and will be a great addition to the council.

We have also � nalised a date for our � rst training session for 2025.

This event is a partnership with the PIA, WEG, Drive Systems and Cancer Council Australia.

Snowmaking pumps power Australian ski �elds

Reliable snowmaking pumps help Australian ski resorts strike a balance between performance and sustainability amid changing climates.

Thredbo’s snowmaking infrastructure ensures its facilities are always at their best for visitors.

Image: Thredbo/EVT

Snowmaking has evolved from a supplementary measure to a cornerstone of operations in Australian ski resorts, driven by sophisticated pump systems that ensure consistent snow cover amid climate variability.

Australia’s alpine regions are facing increasing climate variability, characterised by shorter snow seasons and reduced natural snowfall. Ski resorts can no longer depend on consistent snowfall to attract visitors or deliver viable operating seasons. In response, snowmaking has evolved from an occasional supplement to an essential service that underpins the viability of resorts.

Behind each perfectly groomed run is a highly engineered network of pumps, pipelines, and control systems that move massive volumes of water up mountainsides and across ski � elds. From major operators such as Mt Buller and Thredbo to smaller resorts such as Corin Forest, snowmaking pumps are at the heart of keeping slopes open, safe, and skiable.

This shift has also reshaped the philosophy of snowmaking. As Mt Buller’s Snowmaking Manager, Paul Richmond, explained, “Our snowmaking system has gone from backing up natural snowfalls to being relied upon to create the base itself. It is almost a complete change.”

Australian snowmaking teams now operate with military precision, using advanced monitoring tools and highly e� cient pump systems to produce the right snow, at the right time, in the right place. The modern snowmaking pump is no longer hidden infrastructure, but an essential driver of the ski economy.

Building the snow base: Modern snowmaking in Australian ski resorts Snowmaking’s role in Australian ski resorts has undergone a signi� cant shift in recent decades. Initially viewed as an occasional supplement to natural snow, it has become mission-critical. Without reliable snowmaking, many of Australia’s ski � elds would struggle to deliver a viable season.

At Mt Buller, the history of snowmaking dates to the early 1970s, when a pilot system was tested on the Enzian run. Today, Mt. Buller operates four 300-horsepower multi-stage pumps, delivering up to 400 litres per second across 80 hectares of skiable terrain. The resort now manages 170 megalitres of water for snowmaking,

While the creation of snow may be pre y, it’s vital that everything is considered before the pumps get cranking. Image: Corin Forest

supported by more than 300 snow guns, 80 per cent of which are fully automated. Thredbo launched snowmaking in 1987. Before that, top-to-bottom skiing lasted just 20 to 30 days a season. With modern snowmaking, Thredbo now routinely achieves more than 100 days. Its � eet of more than 300 automatic guns can run up to 200 simultaneously, allowing precise snow management across the mountain.

Corin Forest represents a di� erent model. Located near Canberra, it relies entirely on snowmaking, given the region’s low natural snowfall.

“We are a snow resort where it doesn’t snow,” said owner Dane Liepins. Since 2014, Corin Forest has expanded from one leased snow gun to nine top-tier snowmakers and two snow factories capable of producing 100 tonnes of snow daily.

Switching on the snow: Decisionmaking in snowmaking operations Deciding when to activate snowmaking systems involves balancing weather conditions, operational targets, and economic considerations. Gone are the days when snowmaking was simply reactive. Today, it is a strategic process informed by weather forecasts, water availability, and visitor demand.

Mt Buller typically begins snowmaking two to three weeks ahead of the King’s Birthday long weekend, which marks the

traditional season opening. Richmond explained that the resort uses detailed weather models to plan activations.

“We start with primary slopes � rst, using both our snow guns and allweather snow factories,” he said.

At Thredbo, systems are placed on standby from early May. Test runs ensure readiness, and full-scale snowmaking commences when favourable cold snaps arrive. The resort’s supervisory control system monitors temperature, humidity, and snow depth in real time, helping to optimise when and where to make snow.

Corin Forest’s approach re� ects its status as a small business.

“It’s pure maths,” Liepins said. “We calculate the cost to make snow and how many visitors we need to justify it.”

Balancing energy demands with operational realities

Beyond managing day-to-day energy demands, resorts must also ensure their pumping systems can perform under the full range of extreme conditions their Alpine environments impose. Snowmaking is energy-intensive. Managing power demand is critical for both operational e� ciency and environmental sustainability. Resorts deploy a variety of strategies to control costs and minimise grid impacts.

compressors to reduce peak demand.

“We avoid making snow after 7am whenever possible to reduce costs and grid load,” Richmond said. A large rooftop solar installation helps power the resort’s maintenance facilities year-round, contributing to its broader sustainability goals.

Thredbo operates on 100 per cent renewable electricity. Its snowmaking system consumes about three megawatts during peak operation.

“We adjust operations to � t o�peak tari� windows where possible,” Thredbo Snowmaking Manager Jonathan Batson said.

At Corin Forest, power management is an ongoing balancing act. “We can’t run everything at once,” Liepins said. “Fan guns are more e� cient, so we prioritise them. Snow factories consume a lot of energy, so we use them very strategically.”

Ensuring performance in extreme conditions

energy use, and snow output.

“We can now calculate the cost per cubic metre of snow in real time,” Richmond said.

Thredbo has seen major gains from VSD upgrades.

“We replaced older throttlecontrolled pumps with variable speed models,” Batson said. Future upgrades will focus on further optimising pump control and improving the thermal management of water.

Beyond managing energy demand on a day-to-day basis, snowmaking teams must also ensure their pump systems remain resilient across the full range of extreme conditions.

At Mt Buller, reliability starts with preventive maintenance.

“We conduct biannual vibration testing on all pumps,” Richmond said. The resort also keeps a comprehensive inventory of critical spares to minimise downtime.

Thredbo’s approach is similarly proactive.

“Proper summer preservation is critical,” Thredbo Engineering Manager Russell Nuridin said. O�-season servicing includes disassembling the pump, inspecting it, and performing performance testing.

workshops and have exchange programs with other mountains,” Richmond said. “Feedback from our teams is helping improve snowmaking technology worldwide.”

The resort also collaborates with global suppliers, in� uencing product development based on real-world Australian experience.

Water sourcing, pumping distances and handling head pressure

Of course, none of this e� ciency matters without sustainable water supplies to feed the pumps. Water sourcing is a critical element of snowmaking operations, necessitating careful management to strike a balance between operational needs and environmental responsibilities. Pumping distances and head pressure add further engineering complexity.

Mt Buller sources water from nearby creeks, springs, and rivers. Allocations are tightly controlled by GoulburnMurray Water, with pumping restricted from November to July to protect natural � ows.

Corin Forest’s small team focuses on keeping its equipment adaptable and well-maintained across all weather conditions.

“Snowmaking is inherently highpressure work, often done in the dead of night,” Liepins said.

E� ciency, sustainability, and future directions

Pump e� ciency delivers both cost savings and environmental bene� ts. With energy accounting for a large share of snowmaking expenses, even small improvements in pump performance can yield signi� cant gains.

Mt Buller has embraced advanced software to track pump performance,

Thredbo likewise values peer collaboration. “Within the local operations community, there’s great cooperation,” Nuridin said.

However, competition remains � erce among equipment providers, given the small Australian market.

“That side of the industry is very commercial,” added Batson.

This collaborative spirit ensures that Australia’s snowmaking teams remain at the forefront of global best practice. Whether through formal partnerships or casual conversations, the willingness to share knowledge strengthens the industry as a whole.

Beyond the slopes: Alternate uses of snowmaking equipment

“We often miss valuable spring rainfall because of these rules,” Richmond said.

Thredbo operates a near-closed-loop system. Water is drawn from a lake fed by the Thredbo River, then pumped to the mountain. Meltwater returns to the river.

Corin Forest enjoys a simpler hydraulic pro� le.

“We pump from a 2.5 megalitre dam just 15 metres up the hill,” Liepins said.

Collaboration across the snowmaking industry

Collaboration is a hallmark of Australia’s snowmaking community. While competition exists among equipment suppliers, operators across the resorts freely share knowledge to improve safety, e� ciency, and environmental performance.

“We all talk,” Liepins said. “It’s about sharing practical tips. The little things, like how you dry hoses, move snow guns, or maintain � ttings, can make a big di� erence.”

Informal gatherings and end-ofseason workshops foster this culture of exchange. “Every resort and team face di� erent challenges. Seeing how others solve them is incredibly valuable.”

Mt Buller embraces a similar ethos.

“We participate in international

Snowmaking infrastructure serves critical roles beyond the ski season.

Increasingly, resorts are leveraging their pump systems for asset protection and emergency response, particularly in the face of bush� re threats.

At Mt Buller, this approach is well- established.

“We install sprinklers each summer to defend lifts and buildings from bush� res,” Richmond said. The system is set up well in advance of � re season, with snowmaking pumps repurposed to drive water through rooftop and perimeter sprinklers. “It gives us an additional layer of protection, particularly for high-value assets like lift stations,” he added.

Thredbo operates within Kosciuszko National Park, one of Australia’s most sensitive natural environments. The resort uses its snowmaking system to dampen vegetation ahead of advancing � res.

“It’s an innovative application that has had a signi� cant impact,” Batson said. The ability to rapidly saturate vulnerable terrain helps slow � re fronts and protect both natural and built assets.

Corin Forest’s experience during the 2020 bush� res was a powerful example of this adaptability.

“We used our snowmaking pumps to feed irrigation sprinklers protecting our buildings,” Liepins said. “We were shooting water 40 metres into the air. It worked brilliantly.”

The success of this improvised system has led the resort to invest further in � exible connectors and hardware that can be quickly deployed in emergencies. These examples highlight the broader value of snowmaking infrastructure. Beyond enabling winter operations, wellmaintained pumps and pipelines can play a vital role in safeguarding resorts and their surrounding environments year-round.

Looking ahead: Innovations shaping the future of snowmaking

As climate patterns shift and snow windows narrow, Australian resorts are looking to innovation to sustain their snowmaking capabilities. Pump systems will continue to play a central role in this evolution.

At Thredbo, improving lance gun e� ciency and enhancing water cooling are key priorities.

“Further cooling of pumped water can signi� cantly boost snow production,” Nuridin and Batson said. This allows snow guns to operate more e� ectively at marginal temperatures, expanding the viable snowmaking window. The resort is also investing in all-weather snow factories, providing a reliable means of establishing base cover when traditional methods are not viable.

Mt Buller is pursuing multiple avenues to future-proof its operations. In addition to sourcing more � exible water supplies, the resort is investing in advanced pump controls and expanding its data analytics capabilities.

“We need to be adaptive,” Richmond said. “Improving pumping rates, e� ciency, and water sourcing is critical to the future.” The ongoing pipe replacement program, using highdurability materials, will further enhance system performance and longevity.

At Corin Forest, Liepins is closely watching material science trends.

“High-grade plastic pipe could replace steel in parts of the system,” he said. “It would save time and money on future projects.”

The resort is also exploring ways to further optimise its use of snow factories, balancing energy demands with production needs.

Across the industry, regulatory � exibility remains a shared concern.

“Snowmaking is not traditional irrigation,” Liepins said. “We are building water reservoirs in the form of snowpack, which bene�ts the environment.

Regulators are starting to understand that, but more work is needed.”

All agree the future of snowmaking in Australia will be shaped by innovation, collaboration, and a relentless drive for e� ciency. Snowmaking pumps will remain at the heart of this journey, sustaining the slopes and the communities that depend on them for years to come.

“It has gone from topping up natural snow to building the base itself,” Richmond said. “Every � ake we make supports the entire local economy, from jobs to businesses to tourism.”

Optimising tailings treatment for environmental compliance and resource recovery

As the by-product of mining processes, tailings are a waste stream that may contain toxic by-products or residual commodity materials. Such residual materials may become valuable in the future, depending on technological improvements and market conditions, allowing them to be reprocessed.

Optimising tailings treatment processes is critical to the economic e� ciency, environmental sustainability, and long-term safety of mining operations. As regulatory, societal, and � nancial pressures grow, mining companies are under increasing scrutiny to manage tailings more e� ectively.

It is therefore necessary to monitor the condition of tailings facilities and any leakage or runo� that may occur (for example, after heavy rain). The control of in� ows and leakage typically involves the use of a sump, which is a low-lying pit or basin designed to collect and temporarily store liquids, usually unwanted or excess water. This sump may be used to collect and pump water for reuse or to return it to the tailings

dam. Sump levels must therefore be monitored.

Typically, mill tailings range from sand to silt-clay in particle size and can be highly aggressive substances when they come into contact with pumps, sensors, and valves used to manage them. The technology used to monitor tailings dams and sumps needs to be able to withstand the demands of the aggressive environment in which it must operate.

Bürkert’s solutions for tailings monitoring

The � ow of tailings slurries must be controlled and redirected as necessary by a valve that is una� ected by the properties of the medium. The Type 2380 bellows control valve is a high-performance, pneumatically actuated process valve featuring a polytetra� uoroethylene (PTFE) bellows that ensures complete separation between the medium and the actuator, thereby increasing service life and reliability in harsh environments, such as tailings facilities. The valve is designed for use in aggressive conditions and is easy to clean. All common port connections, up to 25 millimetres, normal pipe size 1 (DN25 / NPS 1), are supported.

Minimising control components also reduces cost and complexity. Bürkert’s Type 8619 multiCELL multifunction controller/transmitter collects data from up to six sensors, allowing for

the simultaneous measurement of temperature, pH, conductivity, and oxidation reduction potential (ORP) value in a single unit. The multi-channel transmitter can also perform a range of dosing, � ow, level, pressure and control functions. Modularity in hardware and software provides high � exibility for adapting to the application’s needs.

With full support for Modbus/TCP, PROFINET (Conformance Class B), or Ethernet/IP, the Type 8619 can be integrated into most industrial Ethernet environments, allowing important process values, such as measurement data, process diagnostics, or device status, to be easily integrated into the automation system.

Bürkert is also able to supply custom control cabinet solutions ready to interface with the tailings process. These control cabinet solutions can contain diverse components, depending on the application, combining pneumatic, electronic, and valve technology in a single unit. They can be highly complex, customised systems with control panels and functions in any suitable housing, including stainless steel.

Bürkert o� ers a broad spectrum of control cabinet solutions and technologies tailored for the application at hand, and customisable to any tailings monitoring and control application.

Reliable pumping performance built on legacy

Regent Pumps delivers consistent, high-performance pumping systems across diverse industrial sectors and challenging legacy replacements.

For more than seven decades, Regent Pumps has played a steady role across Australia’s industrial and rural landscape. From food manufacturing to irrigation and even naval defence, its pumps have delivered dependable performance across changing operational environments.

Founded in 1948, the company remains privately owned, with the third generation of the family still involved. That continuity has shaped a product line de� ned by reliability and practical engineering.

National Sales Manager Tim Yakup sees this as a core strength. “The industries we serve expect solutions that just work, even after decades in the � eld,” he said. “We’ve built our reputation by supporting those expectations, whether it means supplying a new unit or replacing one we made in the 1960s.”

Headquartered in south-east Melbourne, Regent operates a manufacturing and inventory facility in Dingley. This local presence enables rapid delivery across the country, supporting customers in both urban and remote regions where downtime can be costly.

Backward compatibility designed into every build What sets Regent Pumps apart is its

commitment to long-term support. One of the company’s de� ning features is its use of consistent dimensions across product generations. This approach allows seamless replacement of older units without the need to alter pipework or mounting systems.

“It’s not uncommon for us to receive calls from customers looking to replace a pump that’s older than some of their sta�,” Yakup said. “Because we’ve maintained the same critical dimensions, we can o� er a direct swap, even if the original pump is 40 years old.”

This strategy reduces life cycle costs for customers managing legacy infrastructure. The product range includes discharge sizes from 25 to 300 millimetres and o� ers a variety of drive types, including electric, diesel, petrol, and hydraulic.

“We’ve always aimed to be the supplier you call when others say a pump is too old or too hard to match,” Yakup said. “That’s the value of staying consistent over time.”

Evolving with industry through smart innovation

While heritage is central to Regent’s identity, the company is focused on adapting to new demands. As energy e� ciency and sustainability become key priorities, Regent is

re� ning its designs to meet higher performance expectations.

“There’s growing demand for smarter pumps that can do more with less – less power, less maintenance, less intervention,” Yakup said. “We’re integrating sensors and control systems into proven models to extend their value.”

This shift is particularly relevant for the water and wastewater sectors. Utilities are under increasing pressure to improve operational performance, reduce losses, and demonstrate environmental responsibility.

Regent aims to meet these needs by working more closely with customers to align product development with technical requirements.

A future built on legacy and trust As infrastructure operators grapple with ageing assets, uncertain supply chains, and tightening performance expectations, companies such as Regent Pumps o� er a rare combination of local expertise and longterm thinking.

From its commitment to Australian manufacturing to its customer-� rst approach to support and service, the company has demonstrated that reliability is not a marketing slogan, but a built-in feature.

“Our goal is to keep things simple for our clients,” Yakup said. “Whether it’s a brand-new installation or a pump we haven’t seen in years, we want to be the supplier they trust to get it right.”

With its legacy well-established and its future focused on innovation, Regent Pumps remains a vital partner in keeping Australia’s systems running quietly, consistently, and locally.

How high-�ow vertical pumps deliver reliability

High-flow vertical pumps support reliable water transfer in challenging environments and demanding infrastructure projects.

When large volumes of water need to be moved reliably, and suction lift is impractical, high � ow vertical pumps are an essential solution. From irrigation and � ood control to municipal infrastructure and industrial water transfer, these pumps handle demanding � ow requirements with operational e� ciency. Selecting the right pump, engineered for long-term performance, is critical to delivering reliable water movement across diverse Australian conditions.

Selecting the right high � ow vertical pump

High � ow vertical pumps typically fall into three categories: axial � ow, mixed � ow, and vertical turbine designs. Each o� ers distinct performance characteristics.

Axial � ow pumps excel in low head, high volume scenarios, providing up to 10 metres of head with minimal energy use. They are often used in � ood control, dam operations, and river systems.

Mixed � ow pumps balance � ow and head, delivering up to 20 metres of head while maintaining strong � ow rates. They suit irrigation and infrastructure projects needing � exible solutions.

Vertical turbine pumps operate at higher heads, exceeding 15 metres and extending well beyond with multistaging. They are suited to deep well pumping, pit/river pumping, industrial water supply, and urban networks.

While higher heads can be achieved by adding stages to axial or mixed � ow designs, this adds complexity and cost. “Keeping stage count to a minimum simpli� es the design, reduces the number of parts, and improves e� ciency,” according to guidance from Sterling Pumps. Selecting the most appropriate pump ensures optimal performance and reliability.

Reducing maintenance with modern bearing technology

Historically, vertical pump designs, especially inclined and deep

installations, relied on oil-lubricated support bearings. These systems required a constant oil feed, with bearings spaced at 1.5 metre intervals. In deep installations, maintenance demand and environmental risks increased as oil entered the pumped water.

Advances in bearing technology have changed this. Water-lubricated bearings, now used in angled installation turbine/mixed � ow pumps up to 35 metres long, leverage the pumped liquid for lubrication, eliminating the need for pre-lubrication and oil supply.

This reduces maintenance and improves environmental performance, particularly for pumps drawing from rivers, dams, or municipal supplies. Adopting modern bearings extends pump life and lowers operating costs.

Engineering con� dence for Australian conditions

With many projects requiring sitespeci� c engineering, local expertise remains essential. Manufacturers such as Sterling Pumps o� er full design, manufacturing, and testing from Melbourne, ensuring that high � ow vertical pumps meet Australian standards and needs.

Collaborating with engineers during pump selection and structural analysis is particularly important for inclined or deep installations.

Techtop expands VHS motor o�ering for pump applications

Techtop Australia has launched a new range of vertical hollow sha electric motors engineered for reliability and performance in deep well and turbine pump systems. e series aims to meet the growing needs of the water, wastewater, and resource sectors.

Electric motors are the heart of pumping systems across a wide range of industries. When it comes to deep well and vertical turbine applications, few components are as critical as vertical hollow shaft (VHS) motors. Recognising this demand, Techtop Australia has expanded its VHS range to support Australian pump professionals with rugged, highperformance solutions tailored for challenging environments.

The new Techtop VHS series spans from 15 kW to 75 kW in two-pole models and from 15 kW to 300 kW in four-pole options. Designed to handle high axial loads, each unit includes a built-in non-reverse ratchet, high starting torque, and a service factor of 1.15. An enlarged oil chamber helps extend bearing life through better lubrication, while integrated thermistors and heaters ensure the motors perform reliably under varying load and temperature conditions.

A de� ning feature of Techtop’s VHS motors is their hollow shaft con� guration. Unlike conventional vertical motors that require a coupling to connect the motor to the pump shaft, the hollow shaft design allows the pump shaft to pass directly through the motor. This reduces installation time, improves alignment, and helps cut maintenance costs by reducing mechanical complexity. The result is a more streamlined installation process and less downtime in the � eld, which

is particularly valuable for remote or large-scale operations.

Vertical hollow sha motors are designed for deep well and turbine pump systems. Image:

Built for durability, the motors feature a robust insulation system that includes UL (Underwriters Laboratories)approved materials and copper wire compatible with variable voltage variable frequency (VVVF) drives. To enhance resistance to moisture and contaminants, a double vacuum pressure impregnation (VPI) process is used with non-hygroscopic epoxy varnish. Motors destined for harsh conditions such as coastal, mining, or humid areas receive additional tropicalised varnish to shield internal components from damage.

Vertical hollow shaft motors are a preferred choice in various sectors, including water and wastewater management, agriculture, pulp and paper processing, mining, and municipal infrastructure. These industries demand not only high performance but also longevity under pressure. The new VHS motors meet these expectations by striking a balance between technical excellence and practical design considerations.

Techtop’s VHS motors are already proving their value in demanding Australian environments. In regional Victoria, they are supporting deep-bore irrigation, where consistent water delivery is critical to crop viability. Mining operations in Western Australia have deployed the motors for dewatering tasks, where high axial loads and harsh

Municipalities in New South Wales have integrated them into well pump stations servicing growing townships.

In each case, the motors have simpli� ed installation and reduced maintenance overheads. These realworld applications demonstrate how the VHS range meets the practical needs of industry with reliability and minimal operational disruption.

As demand increases for water security and deeper well drilling, especially in regional and agricultural communities, motor reliability is more important than ever. Techtop’s VHS range supports sustainable infrastructure by providing energye� cient solutions that reduce the total cost of ownership over the motor’s life cycle.

Techtop’s national presence ensures timely technical support and the availability of spare parts across Australia. With branches in Melbourne, Sydney, Brisbane, Adelaide, Perth, and Auckland, the company is wellpositioned to serve a broad customer base with specialised motor solutions.

Tailored power, maximum e�ciency

When

it comes to industrial drive systems, e ciency

doesn’t come from a one-size-fits-all solution.

Generic, non-optimised gear motors are often the hidden culprits behind rising energy costs and underperforming equipment. This is evident across multiple sectors, including pumping, wastewater, heating, ventilation and air conditioning (HVAC), mining, and others.

Inconsistent � ow rates, excessive energy consumption, or unplanned downtime can occur when the wrong motor con� guration is chosen, quietly eroding operational performance. Whether it’s over-pumping due to a mismatch in load demands or poor pressure control in booster systems, using a generic drive solution often leads to energy waste and accelerated wear.

In wastewater, for instance, motors that aren’t speci� cally designed for continuous operation or handling varying � ow rates will experience e� ciency dips. HVAC systems often face similar issues; generic setups frequently lead to inconsistent air� ow, resulting in hot and cold spots throughout a building.

Recognising the speci� c needs of each worksite and making con� guration simple is exactly why SEW-EURODRIVE

is a leader in the gear motor space. Multiple ranges of gear units and motors have been designed with speci� c e� ciency and performance requirements for the pumping industry.

The ranges that best exemplify this dedication are the R/RX helical gear units and DRN series motors. These solutions are designed to meet the exact needs of any operation, from moving water through a treatment plant and powering conveyor systems in a mining operation to keeping critical HVAC systems running, all without compromising performance.

Optimised power for any application

SEW-EURODRIVE’s R/RX helical gear units are particularly well-suited for pump-driven systems that require reliable torque and speed control. The singlestage RX series o�ers high output speeds up to 830 Nm, ideal for fast, continuous �ow applications such as booster or circulation pumps. The multi-stage R series, with its �nely stepped gear ratios reaching up to i = 289.74 (or i = 27,001 for double gear units), excels in more demanding systems, such as sludge pumps or multi-stage processing lines,

where torque consistency and durability are critical.

With 15 available sizes, these gear units strike the perfect balance between power and space e� ciency. Additionally, the modular design enables easy con� guration of units for speci� c pump applications, thereby reducing downtime and maintaining overall operating costs.

Energy e� ciency without compromise When it comes to energy e� ciency, the DRN series motors are best in class. With power ratings from 0.09 kW to 355 kW, these motors cover a wide power spectrum and meet the globally recognised e� ciency class of IE3. This

Fast fact

The gear ratio, or the total transmission ratio, is the angular speed of the � rst driving gear divided by the angular speed of the last driven gear of a gear train. The use of i is a convention that has been developed over many years for di� erent industries.

The range of gear motor solutions from SEW-EURODRIVE ensure that almost any industry can benefit. Image: SEW-EURODRIVE

means you can meet strict energysaving regulations without sacri� cing performance, especially in continuous operation settings.

With its S1-rated continuous duty classi�cation, the DRN motor delivers consistent output under full load conditions, making it particularly wellsuited for critical pump systems that can’t a�ord downtime or �uctuating �ow rates.

In chemical dosing and booster pump systems where � ow accuracy is critical, the DRN motors o� er inverter compatibility and integrated encoder feedback, helping operators maintain precise pressure control and avoid costly over-pumping or underdosing.

One of the standout features of the DRN series is the cost-optimised built-in encoder. Traditionally, encoders that provide speed and position feedback are mounted externally, requiring specialised shafts and brackets that add cost and complexity. SEWEURODRIVE’s approach integrates the encoder directly within the motor, eliminating the need for additional components and maintaining a compact design.

Built for � exibility and future-proo� ng

The DRN series also o� ers exceptional � exibility. With multiple pole con� gurations (2, 4, 6, or 8-pole) and support for continuous, inverter, and decentralised operation, these motors can adapt to a wide range of industrial needs.

The DRN Global Motor also meets the world’s most demanding e� ciency standards. No region-speci� c, aftermarket modi� cations will be needed when engaging with SEW- EURODRIVE.

Smarter, more e� cient operations

For businesses seeking to streamline operations, lower energy costs, and minimise downtime, SEWEURODRIVE’s R/RX helical gear units and DRN series motors provide an innovative, adaptable solution. By configuring drive systems to match exact needs, businesses can achieve maximum efficiency without compromise, a critical advantage in today’s fast-paced industrial world.

Giving rotating equipment a second life

Replacing a part is not always the best solution. One company is providing a unique coating solution that can extend the life of pumps.

When a pump fails in a utility plant, the clock starts ticking on downtime, budget overruns, and operational headaches. But what if the solution isn’t a replacement? What if the right coating system could rewind the wear, rebuild the performance, and reset the clock?

Welcome to the world of rotating equipment rebuilds, where polymerceramic coatings transform the maintenance of asset-intensive industries. At the forefront is Chesterton’s ARC coating technology, designed to rescue, reinforce, and futureproof pumps and fans in harsh conditions.

From scrapyard to service: A new rebuild philosophy

The legacy mindset for degraded pumps or fan housings was simple: replace worn metal. However, this incurs costs, delays, and repetitive problems.

Today’s method is smarter. Coating rebuilds restore structural integrity, reclaim hydraulic e� ciency, and o� er greater resistance than the original design. It’s not just about running old assets, it’s about improving them.

Where hydraulics meet high performance

Let’s start with ARC 858. This coating isn’t just tough, it’s smart tough. Formulated to smooth internal surfaces of pumps and � ow equipment, it reduces turbulence, enhances � ow, and resists erosive wear from suspended solids or cavitation.

Maintenance teams use ARC 858 to resurface volutes, impellers, and casings, where micro-erosion a� ects performance. Operators experience immediate e� ciency improvements, achieving up to seven per cent energy savings and signi� cant extensions in mean time between failures (MTBF). In environments where reliability equals revenue, such metrics are crucial.

But what about the equipment that looks too far gone?

The ARC BX series o� ers heavy-duty rebuild composites to quickly and permanently replace lost metal. Whether volutes are corroded or fan blades eroded, BX coatings � ll, reinforce, and restore the geometry for safe operation. Rather than new parts, teams adopt a new mindset: restore and strengthen with a material that � rmly bonds and lasts longer than welded overlays or epoxy � llers.

Ready for the worst case scenario

Pumps handling abrasive slurries or aggressive chemicals often require coatings with high wear resistance. In one mining application, a tailings pump lost more than 12 millimetres of material in six months. A repair using ARC MX1, BX2, and a topcoat of ARC 855 extended the pump’s service life to more than 12 months. Repairs were minimal, with pumps returned to service within 72 hours, resulting in annual savings of approximately $13,700 per unit.

More than a � x: Engineering for reliability

ARC coatings rede� ne asset management, replacing reactive patchwork with engineered resilience. When pumps and fans utilise ARC technologies, it’s a strategic upgradetransforming worn components into high-performance assets for today’s industrial challenges.

This isn’t just a repair. It’s a redesign, with reliability in mind.

Spilling the beans on e�cient food waste handling

Smart air injection technology is helping Australia’s food and beverage sector reduce waste handling costs, lower emissions, and meet stringent sustainability targets.

As sustainability and coste� ciency become critical priorities for Australian food and beverage producers, SEEPEX, a global leader in progressive cavity pump technology, o� ers a transformative solution: Smart Air Injection (SAI). Designed to modernise food waste handling, SAI is a cost-e� ective, energy-e� cient and clean alternative to traditional systems, helping the industry meet evolving environmental and operational demands.

Tackling common industry challenges Food and beverage facilities across Australia face increasing pressure to reduce waste, lower energy consumption, and enhance workplace safety. Yet many still rely on outdated mechanical conveyors to transport by-products. These machines are expensive, maintenance-intensive systems that are poorly suited to modern production layouts, especially those with long distances, elevation changes, or tight space constraints.

SAI replaces these legacy systems with a compact, low-maintenance solution. Its closed piping design eliminates open handling of food waste, reducing odours, safety risks and the potential for contamination. This makes it valuable for operations where cleanliness and process integrity are essential.

Flexible transport of food waste over long distances

SAI is engineered to handle semi-solid and high-viscosity by-products such as co� ee grounds, tea leaves, and mustard husks. It combines a progressive cavity pump with controlled bursts of compressed air to transport these materials e� ciently through closed pipelines. The system reliably moves them over long distances – even around bends and up inclines –without the need for large, costly mechanical conveyors. Its low-pressure pipeline reduces installation complexity and energy use, helping food and beverage producers cut costs and minimise environmental

impact. The system also supports oilfree compressors, which are crucial for facilities that repurpose by-products, such as animal feed.

SAI delivers a strong business case for Australian manufacturers. Initial investment costs are competitive, and the system’s robust construction and low-wear parts result in long service life and reduced downtime. Combined with minimal maintenance needs, this enables a quick return on investment.

SEEPEX’s Rotor Joint Access (RJA) and Drive Joint Access (DJA) technologies enable fast and straightforward routine service. With RJA, operators can access the rotor joint by simply sliding the pump casing. There is no need to dismantle discharge pipework or stators. DJA provides quick access to the drive-side joint, enabling the fast replacement of coupling rods and mechanical seals without the need to remove hoppers. These features save time and lower operating costs.

Supporting sustainable production

In line with Australia’s growing focus on sustainable manufacturing and circular economy principles, SAI helps reduce the use of process water and cuts energy consumption compared to mechanical systems. The importance of sustainable practices in the manufacturing sector is increasing as industries strive to meet environmental goals and comply with stringent regulations.

Heat pumps and the path to net zero: The licensing link

Glenn Evans from the Australian Refrigeration Council (ARC) highlights the importance of sustainability and the path to net zero via the installation of heat pumps. What does this mean for the industry?

Australia’s path to a net zero future isn’t just about ambition – it’s about action. And much of that action is already happening in our homes, through the adoption of cleaner, smarter technologies like hot water heat pump systems.

The recent federal election further underscored public backing for sustainability and climate-conscious solutions. In response, the sector is stepping up to deliver practical, scalable technologies that can accelerate our transition to net zero by 2050.

Among the most promising solutions gaining momentum is the hot water heat pump. Fast becoming a popular alternative to gas, they’re energy e� cient, climate-friendly, and increasingly backed by government incentives. But the speed of this uptake comes with a responsibility: to ensure these systems are installed safely, professionally, and in line with environmental standards.

A key detail that’s often overlooked is that many of these hot water heat pumps, such as split systems, use refrigerants, and if not properly handled, can be harmful to both people and the environment. That means installing or maintaining these units isn’t just general plumbing or mechanical work. It requires specialist knowledge and skill-set.

At the Australian Refrigeration Council (ARC), we’ve long said that working on equipment with controlled refrigerant must be treated with care, backed by formal training and licensing. That’s why the national ARCTick licence exists. This licensing framework is in place to make sure technicians working with refrigerants have the right training and credentials. Without it, there’s a risk that poor installation practices could lead to leaks, safety issues, or environmental harm.

We were pleased to see the recent announcement from the Victorian State Electricity Commission and the Victorian Government expanding their

all-electric housing pilot into Maroondah and the Yarra Ranges. Programs like this demonstrate strong leadership by promoting energy-e� cient homes and driving the adoption of sustainable technologies.

But as this transition accelerates, so too does the need for quali� ed professionals. Any system containing controlled refrigerants, like many heat pump units, must, by law, be installed and serviced by a licensed technician under the Ozone Protection and Synthetic Greenhouse Gas Management Act 1989. It’s not just good practice; it’s a legal requirement.

This ensures three critical things: systems are installed to a compliant standard, refrigerants are managed safely, and households are protected from the risks of substandard work.

By recognising refrigeration and air conditioning as a specialised vocation and maintaining high standards through licensing, we strengthen the

reputation of the sector, the safety, and environmental performance of Australian homes.

The move to a net-zero economy won’t be achieved by technology alone. It will be achieved by the skilled people who bring that technology to life. Let’s make sure they have the support, training, and recognition they need to keep doing it right.

Pumps in mining are critical to e cient water use, safety, and sustainability across Western Australia’s booming resources sector.

Western Australia’s mining sector is powering forward, driven by a global demand for critical minerals and a growing emphasis on environmental responsibility. At the heart of this momentum lies an oftenunderappreciated force – pumps.

From managing groundwater and dust control to enabling smart infrastructure, pumps and pumping systems are crucial for maintaining safe, sustainable, and productive operations. As the 2025 WA Mining Conference and Exhibition approaches, attention is turning to the technologies and partnerships that will de� ne the next era of mining e� ciency.

Pumps in mining deliver safety and sustainability

Western Australia is home to some of the world’s most advanced and sustainable mining operations. According to Mines and Petroleum Minister David Michael, this is no accident.

“Western Australia’s mining sector is

recognised globally as one of the most innovative and sustainable, underpinned by strong environmental regulations and high ethical standards,” he said.

Pumping systems are central to meeting those standards. In underground mines, dewatering systems play a vital role in maintaining safe conditions.

“Dewatering pump systems are also vital for maintaining safe underground mining conditions by preventing � ooding, which is a major safety hazard,” Michael said.

Beyond safety, the industry is increasingly focused on sustainable water use. The Department of Water and Environmental Regulation (DWER) has developed Water in Mining guidelines that emphasise the e� cient use of water, particularly in arid zones. These guidelines encourage miners to reduce waste, manage extraction volumes e� ectively, and utilise high-e� ciency pumping solutions.

The ability of pumps to support water recycling and reduce reliance on fresh supplies is gaining importance.

“Pumping systems also play an essential role in reducing environmental impact by supporting water recycling systems, minimising reliance on freshwater sources, and preventing loss through leaks or ine�ciencies,” Michael said.

Smart technology and collaborative innovation

New technologies are transforming the way water is managed across remote mining operations. From smart pumps that detect leaks to autonomous systems that minimise manual labour, innovation is helping Western Australia’s resources sector meet its environmental and safety targets.

“The use of autonomous technology, smart pumps, and digitally connected pumping systems o� ers signi� cant bene� ts, including removing people from hazardous roles, improving

The State Government has made innovation in sustainable mining a priority, backing technologies that reduce energy use and support longterm environmental performance. In this environment, pump manufacturers and suppliers can play a strategic role, not just as equipment providers, but as collaborators in designing more e� ective systems.

“The State Government encourages the mining sector to collaborate with pump manufacturers by providing feedback to improve system e� ciency, performance, and safety,” Michael said. “This collaboration will drive innovation and design improvements, helping ensure pumping systems continue to support safe and e� cient mining operations across our state.”

Local suppliers bene�t from strategic engagement Western Australia’s economic diversi� cation strategy is creating new opportunities for small and medium enterprises across the supply chain. For pump manufacturers and distributors, the State Government’s Made in WA plan o� ers a clear incentive to invest in local capability and partnerships.

“Our plan will create opportunities for small to medium-sized suppliers, including those in the pump sector, to connect with industry,” Michael said.

One such opportunity is through the Western Australia Industry Link program, which supports Regional

state.

Hosted by the Department of Jobs, Tourism, Science and Innovation (JTSI), the forums help pump businesses understand government priorities, meet prospective clients, and explore ways to align their o� erings with emerging mining needs. This kind of targeted engagement positions Western Australia as not just a mineral-rich jurisdiction but a globally competitive hub for mining innovation, engineering, and advanced manufacturing.

Future-focused skills and conference opportunities

With demand for mining and equipment services on the rise, Western Australia

is investing in its workforce. The State Government has rolled out TAFE courses and industry training programs to prepare workers for the next generation of mining jobs, many of which will rely on data, digital systems, and clean technologies.

“Collaboration between mining companies and the pump industry to build local skills, provide training, and create long-term career opportunities will be key to the sustainable growth of the mining sector,” Michael said.

The WA Mining Conference and Exhibition, scheduled for 9-10 October 2025 at the Perth Convention & Exhibition Centre, will be an ideal forum to explore these themes. The event will feature cutting-edge products, technical sessions, and panels focused on mine site e� ciency, environmental, social and governance strategies, and digital transformation. For pump professionals, it o� ers a timely opportunity to engage with mining companies seeking sustainable water solutions and reliable suppliers.

Michael said the future of the sector would depend on these collaborations, new technologies, and the people who build and support them.

“The pump industry will continue to play an important role in Western Australia’s mining sector, and its ongoing innovation will help ensure our mining operations remain environmentally responsible, sustainable, safe, and globally competitive.”

#15: Why NPSH testing sucks

Noted Russian-American engineer Igor Karassik once said that if all the technical papers wri en about NPSH and cavitation were laid end to end, they would not reach a conclusion. In this commentary, Ron Astall focuses on NPSH testing issues.

Testing a pump to determine Net Positive Suction Head Required (NPSHr) can be problematic, particularly if the NPSHr values are low. Read on to discover why the Test Engineer might be tearing their hair in frustration.

Background

Net Positive Suction Head (NPSH) is a key parameter in a pumping system, as it represents the margin above the liquid vapour pressure. It is a measure of how close the liquid is to vaporising (or boiling). If the liquid vaporises in the pump, it causes noisy, damaging cavitation, which must be avoided to ensure a reliable installation.

NPSHa is the available Net Positive Suction Head (NPSH) in the system. NPSHr is the NPSH required by the pump to avoid cavitation. In simple terms, we need the system NPSHa to exceed the pump NPSHr.

NPSHa is typically presented as the available NPSH at the pump inlet nozzle. However, NPSHa can be calculated at any point in a piping system, as shown in Fig. 1.

Wherever the local pressure drops below the vapour pressure, cavitation, or “� ashing,” will occur. Cavitation is typically considered a pump issue, but it can also occur in piping systems, valves, and � ttings. This will severely disrupt the  � ow.

In the example above, NPSHa drops alarmingly at the highest point in the system. In this example, if the highest point exceeded 12.66m above the system inlet, vaporisation (boiling) would occur. This example is a static

case without � ow. With � ow in the system, friction losses and the e� ects of bends and � ttings will create additional losses and, potentially, vapour locking at the high points.

Testing to determine Pump NPSHr

Testing is ideally performed in a closed test loop, where the loop pressure (pump inlet pressure) is progressively reduced while maintaining a constant � ow rate. For each pump inlet pressure, the NPSHa is calculated from the measured suction pressure, corrected to absolute by adding atmospheric pressure, then deducting the liquid vapour pressure, and � nally converting to head units for plotting.

When the value of NPSHa is reduced su� ciently to cause a measurable e� ect, this benchmark value is noted as the NPSHr point for that speci� c � ow rate. Conventionally, the recommendations of the Hydraulic Institute for a three per cent head drop criterion are followed, as shown in Fig. 2 below. This method is repeated to obtain NPSHr points for � ows across the pump curve, creating a complete NPSHr curve versus � ow.

This approach is generally quite straightforward when demonstrating moderate and higher NPSHr values. So, when does the poor test engineer become more frustrated than a dog trying to bury a bone on a marble � oor?

When pump NPSHr is very low

When the value of pump NPSHr to be demonstrated is low, di�culties may arise in the test loop. A typical Test loop suitable for NPSH Testing is shown in Fig. 3.

A low NPSHa value at the pump inlet indicates a low NPSHa throughout the entire test loop, extending beyond the discharge throttling valve. For a typical cold-water test, an NPSHa value of two metres or less at the pump inlet indicates that the entire loop after the throttling valve will be at a vacuum of at least -80 kilopascals (kPa), which is equivalent to an absolute pressure of less than 22 kPa.

In high velocity areas in the test loop, the pressure will be even lower due to velocity head e� ects (Bernoulli’s Theorem). This can be a particular problem at the throttling valve outlet, where the � ow is constricted. Under these circumstances, vaporisation

(cavitation) at the throttling valve is a major issue, with severe surging as vapour pockets form and collapse in turn, particularly during high-� ow pump tests. Flow control will be challenging, and in some extreme cases, � ow can be lost entirely. The associated acceleration/deceleration heads involved with � ow surging will reduce the measured pump di� erential head and e� ciency.

Another less obvious problem when the test loop is operating below atmospheric pressure is the potential for air ingress through the mechanical seals. Conventional mechanical seals are not designed to withstand vacuum conditions in the seal chamber. They can experience the opening of the seal faces or even the dislodgement of the

outer face under negative pressure. This will allow air to seep into the suction side of the pump, resulting in associated disruptions to hydraulic performance.

For these reasons, it can be di� cult to demonstrate low values of pump NPSHr during performance testing. Although frowned on by most testing standards, using a suction throttling valve ahead of the pump can be a method to maintain higher test loop pressures. Using a suction side throttling valve may transfer the surging problem to the suction side.

When pump NPSHr is extremely low

In the oil, gas, and petrochemical sectors, vertical canned pumps (Fig. 4) may be necessary to handle applications where the available Net Positive Suction

Head (NPSH) is negligible or even zero. In these circumstances, it will not be practical to demonstrate pump NPSHr in a conventional works test scenario.

Where the margin between the customer’s site NPSHa and the pump’s predicted NPSHr is signi� cant, purchaser speci� cations normally waive the NPSH testing requirement based on this margin of safety. An alternative is to test the pump without the suction can by using a temporary hard-piped suction connection.

Past test experience with the same � rst-stage impeller hydraulics in conventional above-ground con� gurations will also be a valid guide.

Conclusion

NPSH testing can be time-consuming and has associated costs. If you have plenty of NPSHa in your process compared to the NPSHr of the pump, an NPSH test is probably not warranted. If NPSHa is low, NPSH testing is undoubtedly a good idea, but be aware of the di� culties and approach it with practicality.

is third part of our installation series, covers the basis of coupling alignment and the factors a ecting misalignment.

COUPLING ALIGNMENT: General

After the pumpset has been grouted in, the foundation bolts tightened, and the suction and delivery pipework fully installed the alignment of all couplings on the pumpset must be checked and if need be, corrected.

N.B., The manufacturer does align the pumpset before dispatch, but transportation and installation can cause the alignment of the pumpset to change.

If the driver has been supplied separately from the rest of the pumpset the driver is aligned after grouting the baseplate.

It is important to note that � exible couplings permit axial movement of both pump and driver shafts and also compensates for thermal expansion. Before beginning coupling alignment ensure that the power supply is isolated from the motor.

When aligning pumpsets it is normal for the pump not to be moved, any adjustment is made to the driver. For outdoor installations make sure extreme temperature do not adversely a� ect the alignment.

Typical Couplings

Notes:

1. Normally couplings do not need to be balanced for speeds up to 3600 rpm, however care must be taken to install correctly. When running at high speed, i.e., beyond 3600 rpm balancing is recommended.

2. Pin and bush couplings are designed

to reduce shock transmission to the bearings etc., and do not compensate for misalignment very well thus should be aligned to the same accuracy as solid couplings.

When checking a couplings alignment the following errors can be expected: Errors in angularity, Fig 2.2, the axis of the shafts are not collinear and intersect in the plane of the coupling faces.

Errors in eccentricity, Fig 2.3, the shafts are parallel but not concentric.

Fig 1.2 Angular Misalignment

Fig 1.3 Correct Alignment

Fig 2.1

Fig 2.2

A combination of the above, Fig 2.4 under these circumstances the axis need not be parallel, and they may or may not intersect. By separating the errors of angularity and eccentricity and measuring them independently, the extent of the combination of errors can be determined and corrected. The axial movement of the pump and drive shafts should be measured. Appropriate allowance can be made for the clearance between the coupling faces.

Other

Factors A� ecting Misalignment:

Apart from the actual misalignment factors, there are three external factors which need to be considered when aligning couplings and these are:

Pipe Strain:

Pipe strain occurs when the pipework connected to the pump places an unnecessary load on the pump � anges such that it a� ects the alignment of the pumpset. This can occur if the suction and discharge piping � anges connecting to the pump are not correctly aligned with the appropriate pump � anges and the suction and discharge pipes and valves are not adequately supported adjacent to the pump � anges.

In addition, pipe strain can also cause de� ection of the baseplate particularly when unrestrained expansion joints are used.

It is recommended that prior to checking the pumpset alignment, after the coupling has been disconnected, that the pump � ange bolts be removed.

There will be no strain on the pump if the � ange bolts slide easily in and out of the bolt holes, otherwise, it will be necessary to � x the piping either by moving it or providing better support.

After the pipe strain has been eliminated it would be expected that when the alignment is checked there will be some misalignment.

Soft Foot:

The external force most commonly found during shaft alignment is soft foot. Soft foot, e.g., a rocking four legged table has a soft foot, is the improper contact between the foot of a pump or motor and the baseplate which supports it. It may be angular or parallel, but usually a combination of both, as shown below.

The main causes of soft foot are:

• The surfaces connecting the mounting feet and baseplate are not in the same plane.

• Deformed mounting feet.

• External forces as applied by pipework and/or brackets.

• Improper shimming or dirty feet.

• To many shims under the feet, a maximum of � ve should be used.

Soft foot should be checked for and corrected before starting the alignment of a pumpset.

Feet are shown in black where signi� cant movement has been noticed.

Thermal Expansion:

The another factor which causes equipment to move once aligned is thermal expansion.

In the case of pumps handling hot liquids this will be a factor as the pumpset is normally aligned when the pump is cold which means that when the pump warms to its operating temperature the alignment will change.

For example – A pump operating at 150 ⁰C with a cast iron casing, a distance of 250 mm from the pump centreline to the pump feet and ambient temperature of 20 ⁰C. Basis a coe� cient of thermal expansion of 0.000010 mm/mm/⁰C, for cast iron, the thermal expansion will be: = T (Change in temperature) x L (Length of material) x C (Coe� cient of linear expansion)

= (150-20) x250 x 0.000010

= 0.325 mm

As can be seen from this example the alignment of the pumpset will be out 0.325 mm when the pump warms to its operating temperature. It is therefore essential that:

a. Allowance for thermal expansion must be made when aligning the pumpset when cold.

b. Ensure the coupling connecting the pump to the driver can accept the change in alignment, normally a spacer type coupling is the most suitable.

It should be noted that if a pump has centreline mount feet then correction for thermal expansion is not required. This article has described the need for coupling alignment and the factors a� ecting coupling misalignment our � nal chapter in this series will cover the actual process of aligning couplings.
