Onga JSK90 0.90kW Self-Priming 304 Stainless Steel Pressure Pump with Venturi Impeller & 24L Pressure Tank

The Onga JSK90 is a premium-quality, Italian-made household pressure pump designed for high performance and exceptional reliability, even in high suction lift applications. With a robust stainless steel pump body, precision-moulded jet, venturi, and impeller, it delivers efficient operation and long service life.

Paired with a 24L pressure tank, the JSK90 offers consistent water pressure, reduced pump cycling, and energy savings—ideal for domestic water supply systems, small farms, garden irrigation, and general water transfer. Its self-priming capability allows for lifts up to 7.6m, making it perfect for installations with below-ground water sources.
