    Water transfer and demanding rural pressure systems are the primary service areas for this high-output 415v FarmMaster OJ800 unit. It is engineered to provide high-volume clean water delivery from deep bores, large dams, and river sources. The pump is optimized for large-scale agricultural irrigation and stock watering where a three-phase power supply is present.

    Operating characteristics include a maximum total head of 123 m and a maximum flow rate of 255 L/Min. This 2.4 kW three-phase motor draws a rated current of 5.7 Amps at 50Hz. These performance parameters define the high-capacity hydraulic output available for the most challenging rural and industrial water transfer tasks.

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

    Construction consists of a heavy-duty Cast Iron pump casing and injector housing for long-term mechanical stability. The internal rotating assembly features a 20% glass-filled polycarbonate impeller and a professional carbon/ceramic mechanical seal with EPDM bellows. This standalone unit is supplied with an integrated pressure switch and pressure gauge.

    FEATURES

    • Rugged Cast Iron pump casing and injector housing ensure structural integrity in high-pressure rural systems.
    • Jet and venturi assisted performance provides reliable suction lift and high-head hydraulic output.
    • Closed polycarbonate impeller reinforced with 20% glass fiber for stability during high-torque operation.
    • Extended suction capability with shallow well lifts to 7.6m and deep well lifts to 49m with appropriate injectors.
    • Integrated pressure switch and pressure gauge are factory-fitted for automatic pressure system configuration.
    • Professional grade mechanical seal with carbon graphite and ceramic faces ensures a watertight motor environment.
    • High-performance 415v three-phase induction motor rated at IP44 for reliable agricultural service.
    • Internal stainless steel shaft sleeve provides superior protection for the motor shaft against corrosion.
