 Engineered Plastic Water Transfer Pumps

Onga Series 120 Self-priming Pumps |
 The Onga 120 Series moulded self-priming pumps are suitable for pumping a wide variety of fluids, including septic tank effluent.
They are surface mounted, and so are far easier to service than submersible pumps. With an open vane impeller and a built in check valve, they have excellent self-priming characteristics, and can handle soft solids without clogging.

Onga 140 Series Hi-flo Centrifugal Pumps |
 Pentair Water is a leader in the use of injection moulding for pump components. This is evident in the Onga 140 series pumps, which couples hydraulic design and corrosion-resistant high grade moulded materials. This provides a general-purpose pump that is suitable for high head water transfer, tank filling, irrigation and circulation duties. Flows of up to 500 litres per minute or heads of over 40 metres are achievable from this range.

Onga 400 Series Hi-flo Centrifugal Pumps |
 The 400 series of Onga Hi-flo pumps are constructed of the same corrosion-resistant materials as the larger 140 series, so they are also ideal for tough conditions. They provide water flows up to 270 litres a minute or a maximum pressure of up to 26 metres.
The Onga model 413 is ideally suited to circulation duty in hydroponic greenhouses or general water transfer, while the 415 is available moulded in heat-resistant materials for high temperature applications, like vat washing and other cleaning operations.
With casings moulded out of strong ABS, these pumps are built to take on the harshest and most corrosive environments.

Onga Model 112 Hi-flo Centrifugal Pump |
 The Onga 112 is of moulded construction and provides a higher head than the 400 series. This suits those jobs involving greater distances or more rugged terrain where a compact water transfer pump is required.
