Onga FarmMaster OJ800 Cast Iron Jet-Assisted Pressure Pump for Stock Watering with 100L Tank

Stock watering and demanding automatic pressure boosting are the core service areas for this high-output FarmMaster OJ800 kit. It is specifically designed to provide high-volume clean water transfer from deep bores, large dams, and river sources. The system manages large-scale rural water delivery while maintaining consistent pressure for automatic stock systems.

Performance specifications for this 2.4 kW single-phase model indicate a maximum total head of 123 m and a maximum flow rate of 255 L/Min. Operating on a 240v supply at 50Hz, the motor draws a rated current of 14 Amps. These data define the high-capacity hydraulic output required for the most demanding agricultural pressure boosting and water transfer tasks.

The pump utilizes a horizontal single-stage surface mounted centrifugal design with jet and venturi assisted performance. This functional setup facilitates shallow well lifts of 7.6m and deep well lifts up to 49m when used with appropriate injectors. The closed impeller configuration is balanced for high-efficiency movement of clean, debris-free water.

Construction consists of a heavy-duty Cast Iron pump casing and injector housing for long-term structural stability. The internal rotating assembly utilizes a glass-filled polycarbonate impeller and a professional carbon/ceramic mechanical seal. This kit is supplied with an integrated pressure switch and a large 100L steel pressure tank for automatic operation.
