Saving water at Sydney Zoo

A splash of innovation: How Sydney Zoo and Sydney Water are working together to reduce water waste – with pumps playing a crucial role.

Divers conduct the weekly cleaning of the shark tank. This takes roughly five hours.

Images: Sydney Water, Sydney Zoo

Sydney Zoo has implemented a comprehensive stormwater capture and recycling system to reduce its reliance on potable water. It involves collecting stormwater runoff and repurposing it for use in moats and garden areas, significantly decreasing drinkable water consumption. By capturing stormwater, the zoo conserves valuable drinking water and mitigates the environmental impact of stormwater runoff.

“We most certainly do have a sustainability focus on water management,” a Sydney Zoo spokesperson said. “All rainwater is captured in the bottom dam, which feeds all the moats throughout the Zoo. With this, we don’t use potable water to top up these moats.”

Suhanti Thirunavukarasu, Sydney Water’s Water Conservation Programs Manager, highlighted the importance of water conservation beyond Sydney Water’s direct influence.

“The interesting thing about the zoo is that they have really taken on board the messages we are sharing with businesses about water conservation and efficiency,” Thirunavukarasu said. “There’s a whole side to water conservation that falls to businesses to step up and use the stormwater they have at their sites. Thanks to this partnership with Sydney Water, we are now able to guide Sydney Zoo through the next steps in their water efficiency programs and complement their stormwater strategy work.”

The zoo’s approach to stormwater management supports its sustainability goals and sets an example for other facilities seeking to optimise their water use. As urban areas continue to grow, finding alternative water sources and improving water conservation efforts become essential in ensuring long-term resource availability.

The role of pumps in stormwater management

The zoo’s stormwater management strategy aligns with broader environmental conservation goals. Effective stormwater harvesting and reuse can alleviate pressure on municipal water supplies, especially during drought or water restrictions. Implementing such a system requires careful planning and collaboration.

Sydney Zoo’s partnership with Sydney Water exemplifies how organisations can work together to achieve environmental objectives.

One of the fundamental aspects of stormwater conservation at Sydney Zoo is ensuring the infrastructure effectively manages fluctuating water levels while maintaining efficiency. Pumps are critical in ensuring stormwater is efficiently captured, stored, and redistributed where needed.

“Even with the Hydraloops that are being trialled across Australia, you need to have a pump to recirculate the water,” Thirunavukarasu said. “It’s a fundamental part of anything where you’re recirculating water because you need to be able to have the pressure to send it back. It’s a key component of these systems.”

Optimising pump efficiency for sustainable operations

Selecting the right pumps is essential to maintaining system efficiency. Pumps must be designed to handle fluctuating demand while operating within an optimal efficiency range.

“When we specify pumps that are used in our system, we look at the system head curves and the different conditions the pumps would have to operate in and come up with a bit of a plan to ensure they’re running efficiently,” Thirunavukarasu said. “We also need to consider energy consumption and heat generation, as these factors directly impact system longevity and operational costs.”

By integrating efficient pumping systems into stormwater management, Sydney Zoo ensures that its water conservation efforts are

both practical and sustainable in the long term.

“The main filtration for the shark tank uses a combination of mechanical, biological, and chemical filtration,” a Sydney Zoo spokesperson said. “The life support system combines glass media filters, carbon filters, foam fractionators, and an ozone generator with a contactor unit.

“These filtration processes work together to tackle different aspects of cleaning and clarifying within the large body of water. With the addition of physical cleaning via dive vacuuming, this process can take up to five to six hours at one time to vacuum the gravel, scrub the walls and furniture, and clean the acrylic viewing area so the public can see the sharks and fish.”

Efficient filtration: maintaining water quality

Ensuring high-quality water is essential in environments housing diverse species. Bull sharks require stable salinity, pH levels, and pathogen control to support their health. Their water must be continuously filtered to remove organic matter, maintain oxygenation, and prevent bacterial growth, mimicking their natural estuarine habitats.

Sydney Zoo’s 1.1 million-litre bull shark tank relies on an advanced recycled water system incorporating ultraviolet (UV), ozone, and chemical treatments.

“Sharks require special considerations,” a Sydney Zoo spokesperson said. “Maintaining an

entire ecosystem balance is essential for their health and welfare. Bull sharks are Euryhaline, which can adapt to varying salinity levels – fresh, brackish, and marine. We keep the tank at five parts per trillion (ppt), whereas marine is 35 ppt. Salt levels also have therapeutic benefits. Temperature is between 22 and 24 degrees, with pH levels between 6.5 and eight.”

This system ensures the water remains free of harmful bacteria while retaining necessary minerals and salinity. Since 2022, it has saved over 30,000 kilolitres of drinking water, demonstrating how advanced water recycling supports marine conservation and sustainability.

Maintaining water quality through advanced filtration

Thirunavukarasu highlighted the similarities between Sydney Water’s drinking water management and Sydney Zoo’s water quality efforts.

“The way the zoo manages water – monitoring daily, checking chemical levels, disinfecting, and removing pathogens – is quite similar to how we ensure Sydney’s drinking water is safe,” said Thirunavukarasu.

Filtration is key to maintaining a healthy aquatic environment. By

implementing advanced technology, Sydney Zoo ensures water quality while reinforcing its commitment to sustainability. To minimise water waste, the zoo captures and recycles 40,000L of vacuum water from the shark tank per dive.

“This water undergoes chlorine treatment and filtration before being safely reintroduced to the system,” a Sydney Zoo spokesperson said. “We still use fresh water to top up what is lost through evaporation and normal system management such as backwashing.”

Energy efficiency: powering sustainable operations

Energy consumption is a critical factor in water management. Sydney Zoo integrates water efficiency with broader sustainability initiatives to minimise its environmental footprint. The zoo spokesperson emphasised how its landscaping supports water conservation across the whole property.

“With all the planting done throughout the zoo, we prevent erosion to ensure we don’t silt up the bottom dam,” they said. “Additionally, with planting through the swale system (a shallow, vegetated channel designed to manage stormwater runoff by slowing, spreading, and infiltrating water), lots of

nutrients and impurities are taken out of the water, ensuring the water in the moat system stays healthy.”

Thirunavukarasu focused on Sydney Zoo’s water side and its work to ensure it makes the most of its precious water resources.

“Sydney Zoo is making the most of every drop they’ve got – that’s recirculating, using alternative water, and improving efficiency in how they manage on-site,” she said. “Even the bathrooms have efficient fixtures and fittings.”

Energy-efficient technologies like variable frequency drives and energy-efficient motors help reduce excess energy use. Smart pump control systems and regular maintenance further optimise energy consumption. By integrating these technologies, Sydney Zoo balances conservation with operational efficiency, demonstrating how targeted infrastructure investments create long-term sustainability benefits.

Collaborative efforts: a blueprint for success

The partnership between Sydney Zoo and Sydney Water is a model for crossindustry collaboration in environmental conservation. Both organisations have

achieved significant water savings and operational efficiencies by combining resources and expertise, demonstrating how private enterprises and public utilities can work together towards shared sustainability goals.

“We are excited by this fantastic opportunity to work together,” said Thirunavukarasu. “They’ve got one big tank that they’re already recirculating the water in, and it’s saved something like 30,000 kilolitres over the past couple of years, which is huge.”

This kind of collaboration enables both parties to leverage their strengths – Sydney Water provides expertise in water conservation and efficiency, while Sydney Zoo offers a real-world application where these strategies can be tested and refined. As industries become more conscious of their environmental impact, partnerships like this highlight the benefits of proactive water management.

Engaging with external partners can also provide access to additional resources, such as funding opportunities and technical expertise.

“It’s about more than just water savings; it’s about knowledge-sharing and innovation,” Thirunavukarasu noted. “By working together, we can identify new opportunities to reduce consumption, improve efficiencies,

and apply these lessons across different industries.”

This collaboration ensures that sustainability projects can be implemented efficiently and costeffectively while paving the way for broader adoption of advanced water conservation technologies in commercial and industrial settings.

Looking ahead: Opportunities for broader application

Sydney Zoo’s strategies offer valuable lessons for other industries and institutions. Implementing stormwater capture systems, investing in advanced filtration technologies, and embracing energy-efficient practices can be adapted across various sectors.

These strategies demonstrate the importance of a multi-faceted approach to water conservation, where efficiency, innovation, and collaboration combine to create meaningful and lasting impacts.

Thirunavukarasu pointed out the significance of Sydney Zoo’s efforts as a case study for other organisations.

“The Sydney Zoo example will help create this visibility of what other businesses could be doing,” she said. “They’ve got that unique combination of having the aquarium and the land animals, so looking at that as a case

study and seeing how other zoos or other businesses can apply similar strategies is a real opportunity.”

Moreover, these initiatives can lead to cost savings, regulatory compliance, and enhanced community relations. They demonstrate a proactive approach to environmental challenges, positioning organisations as leaders in sustainability.

Beyond the direct financial and operational benefits, these strategies reinforce corporate responsibility, demonstrating a commitment to resource management and ecological preservation.

Thirunavukarasu said Sydney Water and Sydney Zoo’s work will likely influence broader industry trends, encouraging more businesses to re-evaluate their water use.

“Every day, we look at innovative ways we can save water while providing world-class animal care,” said a Sydney Zoo spokesperson. “Sustainability is at the heart of our operations, and we are committed to continuously improving and reducing our water footprint.”

“Water is a finite resource, and every drop counts,” said Thirunavukarasu. “By taking proactive steps today, we can create a more resilient future – not just for businesses, but for the communities and environments that rely on sustainable water management.”

Pump testing: The heart of making pumps

With pump performance under growing scrutiny, comprehensive testing has become essential – not only to verify design integrity but also to ensure efficiency, reliability, and compliance across a wide range of operating conditions.

Hydraulic design, 3D modelling, intellectual property (IP), and manufacturing expertise are all vital components in the development of efficient, high-performing pumps. With increasing emphasis on energy efficiency and the ongoing demand for reliability, manufacturers must continually assess and refine design and production methods.

Theoretical design lays the groundwork for pump development. However, casting and machining processes significantly affect how well a design performs in practice. Variations in these processes can lead to discrepancies in final pump performance, making real-world testing an essential step in the manufacturing cycle.

Pump testing verifies whether the intended design translates into operational success. It allows for identifying and implementing improvements, helping to optimise efficiency, durability, and performance.

Testing is equally critical for reconditioned pumps that have been

re-rated or modified to meet new hydraulic conditions.

Melbourne-based manufacturers United Pumps and Sterling Pumps operate two dedicated test facilities that support this process. One is a one megawatt (MW) facility in Pakenham, focused on deep well submersible and vertical turbine pumps, featuring a 15-metre-deep test pit. The other is a 2.5MW facility in Sunshine dedicated to horizontal pumps.

This site includes two independent sealed test loops and a 400,000-litre underground tank. Together, these facilities accommodate flow rates of up to 3000 cubic metres per hour (m³/h) and heads of up to 1800 metres.

These testing environments enable comprehensive performance validation, including flow, head, power, efficiency, vibration, sound, and net positive suction head required (NPSHr). The ability to assess performance across the full operating range – including mechanical run and endurance testing – assures that each pump will operate reliably under real-world conditions.

United Pumps provides end-to-end pump engineering and manufacturing services, covering the full lifecycle from concept and design through to fabrication and testing. The company produces API (American Petroleum Institute) 610-compliant, high-quality centrifugal pumps for the oil, gas and process industries, and for high end industrial and municipal applications. Engineering teams conduct detailed analysis using finite element analysis (FEA) and torsional analysis to ensure mechanical integrity and low-noise, low-vibration operation.

Cutting pumping costs with smarter controls

Outdated pump systems waste energy and money – the latest Variable Speed Drive (VSD) technology slashes costs, improves system efficiency, and enhances reliability.

With energy costs increasing, it is now more important than ever to keep track of energy usage and to implement efficiency solutions in all areas of power consumption. Electric motors account for approximately 85 per cent of the world’s power consumption and is expected to double by 2040. The US Department of Energy has conducted research that suggests pumping systems alone account for nearly 20 per cent of the world’s electrical energy demand.

In some industrial applications, pumping consumes 25 to 50 per cent of the available electricity. Over 80 per cent of this energy is wasted by oversized pumps and lack of control or non-efficient control, such as valve control.

Techtop has partnered with Invertek Drives in the UK and developed a dedicated pump control technology algorithm that pays for itself. A Techtop spokesperson said companies sometimes recoup their costs in less than six months.

The Techtop TTA-3 Eco Variable Speed Drive (VSD) can reduce energy consumption and total system cost, simplify systems by eliminating complex control panels, and improve process control and system reliability.

The system provides energy-efficient, consistent, matched, and pressurised water flow on demand, thanks to built-in motor and pump protection, including dry run protection, pump prime, burst pipe detection and protection, load monitoring, blockage detection, and pump alternation on multipump systems.

Pioneering positive displacement pump technology

Advanced engineering meets industrial resilience – discover how innovative pump technology is solving critical challenges in the mining, power, and chemical industries.

The pump technology behind FELUWA’s growth is rooted in traditional diaphragm and diaphragm piston pumps. The company launched the hose-diaphragm piston pump – a hermetically sealed, leakfree, oscillating positive displacement pump – 50 years ago. This innovation has established benchmarks across diverse industries globally.

In 2002, FELUWA introduced the patented MULTISAFE® double hosediaphragm pump, combining the efficiency of a piston diaphragm pump with technological advancements.

Functionality of the MULTISAFE double hose-diaphragm pump

The crank drive converts the drive motor’s rotary motion into a reciprocating piston movement. This movement is transferred to the double hose-diaphragm via a noncompressible fluid, creating the pumping effect in the pump head.

The hose diaphragm moves in a controlled manner with each pump stroke, ensuring a linear flow without turbulence. This has several benefits, including reducing the risk of sedimentation and mechanical stress while extending hose-diaphragms’ service life.

Due to their design principle, FELUWA MULTISAFE pumps are perfect for demanding pressure levels and large flow capacities. They operate at discharge pressures of up to 350 bar and handle flow rates of up to 1000 cubic metres per hour.

Providing better diaphragm pumps

The MULTISAFE double hose diaphragms inside each pump head create a redundant hermetic seal, effectively isolating the processed media from both the external

environment and the hydraulic drive. This design enhances operational safety while safeguarding internal components. With fewer wetted parts than conventional pumps, the medium remains separate from the pump head and hydraulic section. Depending on application requirements and media properties, carefully chosen materials minimise chemical erosion and wear.

Reliable

performance with abrasive and aggressive media

The MULTISAFE pump operates without dynamic seals, protecting moving components from abrasive and aggressive media. This design increases durability and operational reliability. Additionally, material configurations can be adapted to changing process requirements.

In Australia, FELUWA pumps are widely used in the mining and minerals sector for demanding applications such as tailings disposal, ore concentrate transport, autoclave and leaching processes, filter press feeding and mine dewatering. Their robust design ensures long-term reliability, even in the harshest operating conditions.

FELUWA pumps are also suited to other industries and challenging applications that include reactor feeding, spray dryer feeding, fly and bottom ash disposal from coal-fired power plants, bauxite and red mud transfer, coal gasification feeding, the chemical industry – many, varied applications.

Shaping the future of the industry

The pump industry is undergoing rapid transformation, driven by strategic acquisitions, market consolidation, and an increasing focus on innovation. Companies are no longer content with

maintaining their current positions – they are actively seeking growth, diversification, and new technological capabilities to stay ahead in an evolving global landscape.

These recent acquisitions reflect a broader industry shift, where businesses are aligning themselves with emerging trends in sustainability, digitalisation, and efficiency. The push for energy-efficient solutions, greater automation, and enhanced service capabilities is shaping the sector’s direction as companies strive to meet the demands of modern infrastructure, resource management, and environmental responsibility.

Mergers and acquisitions are not just about expanding product lines but about securing long-term competitiveness. By acquiring specialists in niche markets, larger companies gain access to new customer bases, advanced technologies, and operational efficiencies that would take years to develop organically. For smaller players, these deals provide opportunities for scaling up, leveraging global networks, and accessing greater investment in research and development.

Safeguarding the future of energyefficient heating

With thousands of people across Australia working on pump-related technology and products, we invited Glenn Evans, CEO of the Australian Refrigeration Council (ARC) to contribute to Pump Industry. The ARC is central to the training and licensing of refrigeration technicians across Australia. Image: nikomsolftwaer/stock.adobe.com

Hot water heat pumps are becoming increasingly popular across Australia as an energy-efficient solution for heating water and pools. These systems, which extract heat from the outside air, use about one-third of the energy of traditional electric storage hot water systems. While heat pumps are an excellent choice for reducing energy consumption, proper installation and servicing are essential to meet environmental and safety standards. Heat pumps operate similarly to refrigerators but in reverse, transferring heat from the air into water. They often rely on refrigerants regulated by the Australian Government. While these refrigerants are necessary for the heat exchange process, many are potent greenhouse gases that can contribute to global warming if mishandled. Additionally, some refrigerants, such as hydrocarbons or CO 2, present safety risks due to their flammability or highpressure characteristics.

To support the growing demand for hot water heat pumps and ensure installers are properly trained, the Australian Refrigeration Council (ARC) has recently released a new fact sheet outlining the licensing requirements for installing these systems.

There are three primary configurations of hot water heat pumps commonly used in Australia:

1. I ntegrated Systems: These selfcontained units include a refrigeration system, a combined water tank, and a heat exchanger. Installation requires essential electrical and water connections.

2. I ntegrated Pool Heater Systems: Like integrated systems, these units integrate refrigeration and heat exchange components but do not have a water tank. Instead, they supply heated water directly to a pool.

3. Split Systems: These systems have an outdoor unit with refrigeration components and a separate water tank. Refrigerant pipes connect

the two. Installation requires more expertise due to the need for refrigerant handling. The first two types are sealed systems that do not require refrigerant handling during installation. However, split systems require a licensed refrigeration technician due to the specialist nature associated with high-pressure refrigerant pipes and components.

Glenn Evans is the CEO of the Australian Refrigeration Council.

Installing, servicing, and decommissioning these systems necessitate a technician with the appropriate refrigerant handling licence from the ARC, reflecting the specialist nature of the works.

Technicians with this licence are trained to manage refrigerants safely and minimise emissions, ensuring compliance with environmental regulations.

As the adoption of energy-efficient technologies like heat pumps continues to rise, it’s crucial that we equip professionals with the right skills to ensure these systems are installed and serviced correctly. The ARC is committed to providing the necessary licensing and training to safeguard the environment and the safety of the Australian public.

As Australians increasingly adopt energy-efficient technologies like heat pumps, it is vital to ensure that licensed professionals carry out installation and servicing. At ARC, we remain committed to providing the right skills and qualifications to support this transition to a more sustainable future.

Heat pumps are changing the way Australians heat water and warm their homes.

The need to lead

Sami Zheng, Chief Executive Officer of the Australian Institute of Refrigeration, Air Conditioning and Heating (AIRAH), reflects on a tumultuous few months in global politics and what they could mean for Australia’s sustainability goals.

For those of you who are not familiar with AIRAH, we’re a member organisation and the peak representative body for the Australian heating, ventilation, air-conditioning and refrigeration (HVAC&R) building services industry. Our members range from refrigeration and air conditioning technicians (affectionately known as “fridgies”) to mechanical engineers and experts in fields like indoor air quality, infection control, electrification, building physics, big data, and system commissioning.

We’re aware that our industry is essential for the functioning of modern life as we know it, but we also know that it has a significant impact on the health of the planet. According to the World Green Building Council, the built environment is responsible for 39 per cent of the world’s greenhouse gas emissions, with heating

and cooling responsible for the bulk of that energy use.

That’s why, since the turn of this century, one of AIRAH’s primary focuses has been improving sustainability in the Australian HVAC&R industry. We promote the use of refrigerants with low environmental impact, as well as smart design and technologies such as heat pumps that reduce the energy required for heating and cooling.

We’re lucky to have great support from within the Australian HVAC&R industry. But with the global political order experiencing upheaval, can we count on similar support from the political sphere in the future?

Deregulation frenzy

While Donald Trump’s recent imposition of widespread tariffs has stolen global headlines, a much

more serious development has gone largely unnoticed. A few days before I wrote this article, the USA’s Environmental Protection Agency (EPA) announced plans to repeal several key environmental regulations.

These include caps on CO 2 emissions from power plants, classifications of greenhouse gases as harmful to public health, and regulations encouraging the uptake of electric vehicles.

The success of these repeals remains uncertain, but the concern is that the EPA’s stance appears to be shifting away from its core mission of protecting the environment. While there is no immediate indication of similar rollbacks in Australia, history has shown that policy shifts in the United States can influence Australian discourse – we have already heard rumblings, for example, about freezing energy

efficiency provisions in the National Construction Code. The potential rise of climate scepticism could hinder progress on sustainability initiatives, making it crucial for industries to lead by example rather than wait for government directives.

Unconditional leadership

The lesson I take from this is that leadership from organisations such as AIRAH and Pump Industry Australia is more important than ever. We can’t rely on governments to set the tone; we need to promote best practices to our own members.

After all, they’re in the best position to understand the issues affecting sustainability in our industries, how to address them, and why doing so is vital. We must push harder than ever to promote sustainable practices within our industries, regardless of what’s happening around us. Our planet is counting on us.

Global influence of pump progress at AIMEX

Smarter, longer-lasting pumping solutions keep mining operations efficient, reliable, and sustainable as the demand for resources grows.

The Asia-Pacific’s International Mining Exhibition (AIMEX) is Australia’s longest running mining event, bringing together suppliers, manufacturers, and decision-makers from across the sector.

It provides a stage where innovations can shine, allowing industry leaders, engineers, and executives to explore cutting-edge technologies that push mining operations towards a more sustainable and efficient future.

With advancements in materials, energy-saving designs, and predictive maintenance, the sector is redefining what it means to keep the industry in flow.

For an industry built on moving mountains, avoiding equipment downtime is essential. Every minute a pump is out of action, mining companies haemorrhage money, efficiency, and, increasingly, sustainability credentials.

Equipment failures lead to costly delays, safety risks, and lost productivity, making reliable pumping solutions more critical than ever. The search for efficiency extends beyond

just maintaining operations. Mining companies are looking at ways to optimise existing systems, enhance durability, and reduce environmental impact. Innovations in pump technology, wear-resistant materials, and energyefficient designs are making a tangible difference in how resources are extracted and processed. Reducing downtime isn’t just about improving operations but creating a more resilient and responsible industry. Because in a sector where every second counts, the right equipment can mean the difference between profit and loss.

Why pumping matters in mining

With a legacy spanning nearly half a century, Global Pumps has built its reputation on keeping the mining industry moving – literally and figuratively.

Its expertise lies not just in supplying pumps but in delivering tailored solutions that address the unique challenges of mining operations. From tackling extreme wear conditions to improving energy efficiency,

Global Pumps offers a range of products designed to perform in the harshest environments.

Beyond reliability, longevity is key. Global Pumps’ solutions extend the lifespan of critical equipment and contribute to a more sustainable, cost-effective approach to resource extraction.

A leader in mining’s toughest conditions

From gold mines in Victoria to major nickel operations in Western Australia and across the world, Global Pumps has built a reputation for delivering longlasting solutions.

Darren Seeley, Sales Director at Global Pumps, believes that the company’s edge lies in helping mining operations extend the life of their pumps beyond conventional expectations.

“Our biggest point of difference is focusing on longer-lasting products,” Mr Seeley said. “For example, we worked with a nickel client in Western Australia that operates a number of mine sites across the state. We introduced our

Verderflex hose inside their existing hose pumps. The trial period alone saw pump life triple. Over time, they achieved ten to 12 times the lifespan they were getting before.”

He said it’s a story that’s played out across the industry. When a gold mine in Victoria trialled impellers from Global Pumps’ SlurryPro range, it reported twice the wear life compared to their previous slurry pump impellers.

Mr Seeley said that these case studies are not just technical wins but also proof of how better pumping technology directly benefits those working on the ground.

“We love hearing from end users who tell us that our pumps mean fewer breakdowns, fewer headaches, and more time at home with their families,” he said.

AIMEX: a showcase for mining’s future AIMEX is more than just a trade show. For Global Pumps, it’s an opportunity to connect with boots-on-the-ground operators and high-level executives looking to drive innovation.

“AIMEX brings together everyone from frontline workers to decisionmakers,” Mr Seeley said. “It is where new ideas get tested and where sustainability, efficiency, and uptime come into focus. These are the exact conversations we want to be having.”

With the mining industry under increasing pressure to improve sustainability and reduce downtime, Seeley said that the event is the perfect forum for discussing solutions.

“The industry is in a constant state of improvement. Sustainability isn’t just about reducing carbon footprints – it’s about making processes more efficient, reducing waste, and ensuring equipment lasts as long as possible,” he said.

A bold move to Adelaide

AIMEX will take a significant step in 2025 by relocating from Sydney to Adelaide, where it will be centred for the next ten years. While Sydney has long been the event’s home, Seeley sees the shift as a strategic move that better aligns with Australia’s mining geography.

“The majority of mining activity happens on the west coast,” he said. “South Australia, with its major copper deposits and operations like Olympic Dam, Carrapateena, and Prominent Hill, plays a crucial role in the sector. Moving AIMEX closer to these operations makes sense.”

Mr Seeley said the new location removes perceived barriers for attendees from major mining hubs and allows for greater engagement across all levels of the industry.

Reliability is essential for maintaining mining operations for extended periods of time.

“This opens up the event to more mining companies, including those who may have found it difficult to justify the trip to Sydney,” he said. “It’s a bold decision, but one we applaud.”

What’s next for pumps in mining?

As the industry evolves, so does Global Pumps. The company is positioning itself as a supplier and solution provider of choice, ready to tackle the sector’s biggest challenges.

With the move to Adelaide, multiple conference stages and expansive exhibition floor, there is enormous potential for pump industry participants to highlight their contributions to this vital sector at AIMEX in September.

At AIMEX, Global Pumps will showcase these solutions and more, ensuring mining companies leave with practical ideas they can implement immediately. Looking ahead, Mr Seeley sees AIMEX as an opportunity to build relationships that go beyond selling products.

“Our goal is simple,” he said. “We want to change the lives of miners and mining companies from that day onwards.”

Seals under pressure #14: Understanding seal chamber pressures, part 3

Ron Astall knows pump engineers want a stable liquid film at the seal faces. Venting, cooling and pressure control are ways of achieving this.

Previously, he outlined the role of primary seal flush plans as providing a better environment for our mechanical seals.

Why have a seal flush?

API 681 / ISO10349 standards define standardised piping plan layouts, which are helpful across all pump types and applications. A selection of common primary piping plans and their expected impact on seal chamber conditions are shown below.

In the last article, we looked at the simpler plans 01, 11, and 13. These plans provide flow through the seal area, which may limit heat build-up and, with appropriate pump construction, adjust liquid pressure at the seal faces. Pressure management in the seal chamber can be critical if we pump liquids close to their vapour pressure. That is, for liquids that are close to boiling (vaporising). For these situations, providing additional, positive cooling to lower the vapour pressure is a great advantage. Other difficulties that we may face include solids or just plain awkward and unpleasant liquid properties.

Following is a selection of additional, more sophisticated piping plans that can be very helpful.

Plan 23 Cooling Loop

This plan involves a recirculation loop through the seal chamber via an external cooler. A pumping ring in the seal is required to positively recirculate flow through the cooling loop. Typically, there will be a throat bush at the inboard end of the seal chamber to limit the mixing the hotter liquid in the pump with the cooled liquid in the seal chamber. This makes for an efficient arrangement because it reduces the ongoing heat load at the cooler. This simplified diagram does not show the high point vents (Fig 5), which ensures the cooling loop is fully primed with liquid. Vapor locking must be avoided. Ideally, piping runs will be sloped appropriately to encourage a thermosyphon flow when the pump is not operating. Inverted loops or high points must be avoided.

Plan 23 will not increase seal chamber pressure, but it is excellent at reducing the temperature. This improves the pressure margin above the liquid vapour pressure and

Popular Seal Flush Piping Plans

reduces heat transfer along the shaft to the bearings. It is the “go-to” plan for water above 80° C, particularly in Boiler Feed Pumps. Above 80° C, water loses its lubricity and may even flash (vaporise) at the seal faces.

For similar reasons, this plan is also standard in chemical and hydrocarbon services when there is a risk of flashing the pumped liquid at higher temperatures. The continuous recirculation aspect allows much smaller coolers than a once-through system. As mentioned earlier, the most critical design and installation tip is to achieve complete venting.

Plan 31 Cyclone Separator

Similar in principle to Plan 11, Plan 31 provides a flush from the discharge to the mechanical seal, with the additional feature of a cyclone separator. The cyclone will separate out limited small solids, with the “clean” leg going to the seal and the “dirty” leg returning to the pump suction. See Fig 6.

As with Plan 11, this provides a flow through the seal, preventing heat build-up with the advantage of a degree of solids removal. A cyclone works best where the specific gravity of the solids is at least twice that of the pumped liquid, such as with sand or pipe slag. Unlike a filter, the cyclone does not require cleaning.

However, Plan 31 is not suitable for large solids or slurry applications. The differential pressure between the highpressure connection and the seal chamber & pump suction must be sufficient to drive the cyclonic action – typically 150 kPa as a minimum.

Plan 32 External Clean Injection

Install Plan 32, and the Mechanical Seal will be your best friend. Properly engineered with a compatible clean liquid, the seal will have ideal operating conditions. A throat bush at the inboard end of the seal chamber will often be installed to boost the chamber pressure and prevent dilution of the clean liquid (see Fig 7). So why not use Plan 32 all the time?

First, a suitable clean liquid must be economically available. Second, the liquid must be compatible with the pumped liquid and the process. Common concerns are whether the product’s dilution is acceptable and whether there will be removal and disposal costs associated with the introduced flush. If specialised, the flush liquid can be an expensive consumable.

One elegant approach I have seen is using a Plan 32 flush to metered inject a process additive via the pump seal chamber. One disaster I have seen is using Light Cycle Oil for a Plan 32 flush. The Pump was operating at 365° C. The Light Cycle Oil simply vaporized as it entered the seal chamber, making the seal’s life worse, not better. Nevertheless, where viable and convenient, Plan 32 is a great way to manage a Mechanical Seal’s environment.

What’s the importance of a seal flush?

The standards define standardised piping plan (flush) layouts, which are helpful across all pump types and applications. A seal flush plan is often indicated to provide a better environment for the mechanical seal. The aim is to provide a stable liquid film at the seal faces.

An appropriate seal flush plan can manage seal chamber venting, cooling flow, and pressure control. Our discussion has focused on the common “primary” seal piping plans, which directly affect the seal chamber conditions.

The next step is to determine the type of mechanical seal.

The “primary” seal flush plans above are probably all we need for single seals in nonhazardous service. Dual seals will usually come into play when sealing particularly nasty, dangerous, flammable or toxic liquids. We then need to consider the myriad of specialised “secondary” seal piping plans.

Secondary Seal plans manage the conditions inside the seals, which may be incredibly complex. A fancy dual seal management system may cost more than the pump itself.

Secondary seal systems are a topic for another day.

The ISTT’s International No-Dig is Landing in Auckland in 2026

New Zealand International Convention Centre, Auckland 28 – 29 October 2026

International No-Dig provides an unparalleled opportunity to connect with the global trenchless technology industry. Hosted each year in a different country to showcase the global industry, International No-Dig will bring together the best of the innovations and advancements in trenchless technology.

Installation of associated pipework

This article continues the series on pump installation and covers how the suction and discharge pipework should be installed, including baseplate mounting and the different types of bases.

Suction Pipework:

It is good practice to have the suction piping as short and straight as possible. If practical, a straight length of 10 times the suction pipe diameter is recommended.

Inadequate sump design leads to entrained air bubbles and turbulence, which will damage the pump.

A submerged inflow pipe and tank baffles prevent turbulence and bubbles from entering the suction pipe. Keep the suction pipe short and

straight and eliminate all possibility of air pockets being trapped in the suction line, i.e., ensure the suction pipe rises continuously to the pump.

Air trapped in the suction system will reduce pump performance.

The diameter of the suction pipe is sized to suit the application and is often larger than the pump suction connection and provided with an eccentric taper which should be installed as shown in Figure 1.

The correct distance between the inlet

flange of the pump and the first elbow must be at least five pipe diameters.

Suction Strainers:

It is strongly recommended that suction strainers be installed in the suction line. For pumps drawing from rivers, dams, and open tanks, a suitable strainer should be installed at the start of the suction line to prevent debris that is too big from passing through easily.

In the case of a closed circuit system, which does not require a strainer because the fluid being pumped is clean, it is recommended that a temporary strainer be fitted in the suction line to prevent construction debris from clogging and damaging the pump.

This strainer can be removed once the pump has been run for a few hours. As a guide, all strainers should have a surface area at least three times the pipe diameter.

For temporary strainers, the screen should be made of No.12 mesh and reinforced with No. 2 mesh and 12.6 mm wire. For all other strainers, the screen should be sized to stop solids larger than the pump can easily handle.

Discharge Pipework:

Install the discharge pipework according to the provided drawings or, if no drawings are available, according to proper industry practice.

The common discharge arrangement consists of a pipe reducer, a non-return valve to prevent backflow when the pump is stationary, and an isolating valve for maintenance purposes.

All these valves and pipework must be separately supported so that the pump casing does not bear their weight.

N.B. It is quite common for pumps to be fitted with flexible pipe connections on the suction and discharge, in conjunction with anti-vibration mounts under the baseplate. In this case, it is imperative that the pipework is correctly supported even when no anti-vibration mounts are fitted.

Figure 1

Figure 2

Pipe Expansion Joints:

When installing pipe expansion joints, ensure the following:

1. T he expansion joint must have the correct pressure rating for the application.

2. W hen necessary, tie bolts will be needed to absorb the hydraulic loads in the discharge line from being transmitted to the pump set; if not, these loads can distort the baseplate.

Spring Mounts:

These are often used in conjunction with expansion joints.

Spring mounts are selected so that they deflect to half their deflection when the pump is mounted.

Seismic (restrained) anti-vibration mounts are required for earthquake zones, in accordance with the relevant standards). Some mining sites also specify them.

Baseplate types:

Skid-type baseplates are used for portable units, which are regularly moved around sites for ease of handling and are more robust than standard baseplates.

Pipework general:

1. A ll suction and discharge pipes and valves must be separately supported to prevent the pump from carrying their weight.

2. I f the pump is to be installed between fixed limits, it is recommended that it be temporarily connected to the pipes before it is grouted in.

3. W pump, the pipes should be taken to the pump, not the pump to the pipes.

4. Suction and discharge pipes should be firmly tightened after grouting is complete and before the final alignment check.

5. If the unit is installed outdoors, care should be taken to ensure that extremes of ambient temperatures do not adversely affect the alignment. The pump is installed on its foundation, grouted in and connected to the suction and discharge pipes and valves.

Summary

This article has continued the process of pump system installation such that the pump and its base and pipework are at a stage where they are almost ready for starting.

We will complete the process in the following articles on the alignment of the pump and driver, which is necessary before initial pump start-up.

How do you maintain an airoperated diaphragm pump?

Air-operated double-diaphragm pumps are known for their reliability, but even the best pumps can fail without routine maintenance. Here’s how to extend their lifespan and ensure optimal performance.

Like any piece of equipment, air-operated double-diaphragm (AODD) pumps need routine maintenance and repair to ensure longterm durability.

Correct maintenance is essential for ensuring the efficient and reliable working of a diaphragm pump.

Key factors to consider for preventative maintenance are:

• D iaphragm lifetime

• Compressed air quality

• Flushing of pumps after use.

How to maintain a diaphragm pump: Check the diaphragms regularly: Diaphragms are the most critical component of a diaphragm pump and can wear out over time. Check them regularly for signs of wear or damage and replace them as needed.

Inspect valves: Valves are also important components of a diaphragm pump. Inspect them regularly for signs of wear, corrosion, or other damage. Replace any faulty valves as soon as possible.

Check the fluid inlet and outlet: regularly for signs of clogs or other obstructions. Clean them out as needed.

Lubricate moving parts: Diaphragm pumps have several moving parts, such as the air motor and the valve mechanism. Lubricate these parts regularly to prevent friction and wear. Check air supply: Diaphragm pumps operate on compressed air. Check the air supply regularly to ensure the pump receives adequate air pressure and volume.

Inspect fittings and connections: Check the pump’s fittings and connections regularly for signs of leaks or damage. Tighten or replace any faulty fittings as needed.

Clean the pump: Clean the pump regularly to prevent the build-up of dirt, debris, or other contaminants that can interfere with the pump’s performance.

Maintaining your AODD pump often

starts with choosing the right pump for the right application. Consult a knowledgeable pump supplier such as Kelair Pumps to discuss your pumping requirements.
