Power Equipment assembles custom commercial pump systems for Davey Water Australia – a unique partnership that has existed for some ten years now. Matching the legendary Yanmar TNV series engines and John Deere engines to Davey pump designs delivers some of the best custom pumping systems money can buy.
Iconic Australian brand Davey Water Australia enjoys a relationship with Power Equipment that has seen the expertise and quality products of two companies combine in the best way.
For more than 90 years, people have trusted Davey to deliver water where it matters most — from household pressure and safe drinking water to fire protection, flood defence, pools, spas, farms, and businesses. They build their products for some of the world’s harshest conditions.
While long recognised in domestic pumping, water treatment, and pool markets, Davey has broadened its horizons in recent years, expanding into commercial pumping, irrigation, and large-scale water-transfer and irrigation systems. High-volume commercial and custom pumping systems is where the Davey/Power Equipment story has become renowned.
Custom pumps using Yanmar and John Deere power
Whether Davey’s customers are looking for float-controlled water transfer and irrigation, or perhaps a commercial-grade pressure demand pump, there’s a lot to consider when it comes to moving high volumes of water.
Davey relies on Yanmar TNV series pumps across virtually every horsepower variant and John Deere options available through Power Equipment to get its ISO-rated pumping systems doing their job.
Says Davey’s pump designer Brijesh Patel; “We look at each application on a case-by-case basis.”
“Every pump is a custom build and we size the engines from Power Equipment to match both the pumping demands and site conditions,” says Patel.
Pump expertise is one thing of course, but a unique arrangement that sees Davey custom pumps built and shipped direct from Power Equipment’s Melbourne hub is the “secret recipe” of this successful partnership.
The power to pump!
Yanmar’s TNV series diesel engines have earned a strong reputation in pumping applications, and for good reason.
First, they’re built for continuous, heavy-duty operation. With a robust cast-iron block, forged steel crankshaft, and precision balancing, TNV engines deliver long service life even under demanding 24/7 pumping workloads.
Second, they’re known for fuel efficiency and clean combustion. Yanmar’s direct injection system ensures reliable starting, low fuel burn, and reduced emissions — a big advantage where pumps often run for hours on end.
They provide strong torque across their rev range, ideal for maintaining consistent pump performance without strain.
John Deere takes up duties with the 4045 series where the TNV range reaches its upper power options.
The famous green engine blocks of John Deere stationary engines are workhorses in the pumping world, trusted for irrigation, dewatering, and industrial applications where uptime is critical.
John Deere diesel engines are built with heavy-duty components — robust blocks, forged-steel crankshafts, and high-strength connecting rods — giving them the staying power for continuous operation. They are world-famous for delivering strong lugging ability, ensuring pumps keep steady flow and pressure even under variable or heavy load conditions.
Power Equipment’s Steve Harvey further explained the design that has gone into Davey commercial pump builds with Yanmars and John Deere engines.
“For a start, we match engines to their pumping application at around 75 per cent of the engine’s duty cycle,” Harvey said.
“This gives room for higher volumes or extra work in the real-world applications and caters for extremes in environmental conditions too.”
Power Equipment has also helped develop an improved coupling system between engine and pump for longer life and better reliability.
“We don’t direct couple (tie couple) the engine to the pump with the Davey pumps we assemble,” Harvey explained. Our system uses a flex plate, drive shaft and pump hub which eliminates vibration issues and avoids the difficulties of getting accurate alignment of couplings that stay where they are supposed to be.”
It keeps maintenance simple, with just two uni-joints to grease on a coupling system that keeps running smooth.
“It’s low-maintenance and we have zero issues with it – it’s the best way to run these combinations,” Harvey says proudly.
Completed pumps are shipped direct from Power Equipment to Davey’s clients, with engines turn-key and ready to go. This means the Davey and Power Equipment partnership delivers a machine that is ready to pump hard from the day arrives at the customer’s site.
