The Onga JJ600 FarmMaster Junior is a heavy-duty cast iron jet assisted pressure pump designed for reliable water supply in rural, agricultural, and domestic applications. Featuring a strong cast iron pump casing and injector housing, the JJ600 uses jet and venturi assisted performance to deliver powerful pressure for irrigation, stock watering, and general water transfer systems. The pump can be configured as either a manual or automatic pressure system, making it suitable for a wide range of farm and property water supply installations.
Powered by a 1.1kW electric motor operating at approximately 2900 RPM, the JJ600 produces flows of up to 137 litres per minute and can achieve a maximum head of 63 metres. The jet-assisted centrifugal design allows the pump to handle both shallow well suction lifts up to 7.6 metres and deep well applications up to 37 metres depending on injector configuration.
Engineered for durability and dependable performance, the pump incorporates glass-filled polycarbonate impeller components, ceramic and carbon mechanical seal faces, stainless steel springs, and nitrile sealing components. Designed for pumping clean, non-aggressive water without solids, the pump operates within water temperatures from 1°C to 55°C and includes a pressure switch and gauge for reliable system control.
