The Onga JS90 self-priming jet pump is designed for domestic water supply, pressure boosting, and general water transfer applications where higher flow and pressure are required. It is suitable for drawing water from wells, tanks, and underground sources, making it ideal for residential, agricultural, and light industrial use.
Constructed with a robust stainless steel pump casing and mounted on a high-quality corrosion-resistant base, the JS90 is built for durability and long service life. The pump incorporates precision-moulded internal components including the jet, venturi, and impeller to ensure efficient hydraulic performance and reliable operation under demanding suction conditions.
The pump delivers a maximum head of 43 m (shut-off head) and a maximum flow rate of 80 L/Min based on the performance curve. It provides stable pressure across a wide operating range, supporting both continuous and intermittent duty applications. The self-priming design allows suction lift up to 7.6 m when used with a foot valve.
Powered by a single-phase, enclosed fan-cooled motor, the JS90 operates on 230V supply with a nominal output of 0.75 kW. The motor is equipped with built-in thermal protection, IP44 protection rating, and Class F insulation, ensuring safe and reliable continuous operation.
