Onga OJ800 2.40kW FarmMaster Junior Compact Irrigation Jet Pump with Pressure Switch & 100L Pressure Tank

NOTE: INJECTORS TO BE PURCHASED SEPERATELY (FRONT SUCTION SIDE)

The Onga FarmMaster OJ800 with 100L pressure tank combines the superior pumping performance of Onga’s flagship Jet (OJ) series with the added storage and system efficiency of a large-capacity pressure vessel. Engineered for domestic, rural, and light industrial applications, this high-performance unit is designed for longevity, reliability, and reduced pump cycling.

The OJ800 pump features a horizontal, single-stage centrifugal design with a closed impeller for pumping clean, debris-free water. Precision-engineered internals and a coated cast iron pump body ensure strength and corrosion resistance, while advanced jet and venturi technology deliver exceptional suction and pressure performance.

Paired with a 100L pressure tank, this setup provides a smoother, more consistent water supply, reducing motor wear and extending pump life. The pressure switch allows fully automatic operation, making it ideal for supplying water to homes, irrigation systems, and stock watering points.
