Built with quality components and designed for ease of service, these pumpsets are designed to last a long time

Developer W&P Pumps says its range of irrigation and dewatering pumpsets are built with quality components to endure tough Australian conditions.

Built in China to their own specifications, the pumpsets combine W&P’s rugged pumps with the Legend range of diesel engines, creating pumpsets specifically for irrigation and drainage purposes.

W&P Pumps manager Zac Surplice told Farms & Farm Machinery that the company had been distributing and servicing Legend engines for over 25 years.

The pumps use the 21kW Legend 490 engine, the 33kW Legend 4102 and the 42kW Legend 4108, with pump ports ranging in size from six to 12 inches (15 to 30cm).

"We have found them to be most efficient within the 1,500 to 1,800 rpm range – which suits pumps of 6–12 inches in diameter," Zac says.

"Once you get over that, what we normally do is mount a marine gearbox on the back of the engine – that is a much more efficient way of transferring energy from the engine to the pump than your standard old belt and pulley setup."

W&P Pumps owner Wayne Surplice says the company goes out of its way to ensure the engines it uses are built with quality components and come equipped with large capacity radiators, to better to deal with the Australian heat.

"They come with a flexible drain hose on them for ease of service so you can drain the oil easily," he says.

"They also come standard with electronic engine protection, and you can also add a 4G monitoring control, bringing irrigation into the technology age," he says.

All the pumpsets come fitted with the Smartgen watchdog pump control system, designed to be durable and resist damage from vibration, heat and other environmental influences.

The watchdog features include automatic start and stop, as well as data measurement and alarm protection.

Zac adds that the engines are also designed as a wet sleeve motor, making them easier to rebuild, and come with spin-on oil filters and stub shafts of the back of the motor’s flywheel guards.

"We use solid engine mounts on the sub frame if we are running a tyre coupling off the back of the motor, or we use rubber engine mounts to reduce vibration, and we run a PTO [power take-off] shaft off the back of the motor," he says.

"All our frames are heavy duty and come hot dip galvanised for corrosion protection."

W&P fits the pumpsets with either mixed flow pumps or self-priming pumps – with Zac saying the 21kW Legend 490, equipped with an eight-inch (20cm) HBG-35 mixed flow pump, was the most popular unit.

"With the pumps we have got NSK Japanese bearings and a 2CR13 stainless steel shaft and sleeve, which is a harder wearing stainless steel," Zac says.

"We have also got a brass impeller that we loctite our impeller nuts on, we use marine grade paint on our pumps and mechanical oil bath seals, which means the pump can run dry for longer than a standard pump."

Wayne adds that the company has a strong supply of spare parts available from its base in Kyabram, Victoria, as well as an around-the-clock breakdown service and an attitude of accountability for keeping customers happy.
