Onga JSP90 0.90kW Self-Priming 304 Stainless Steel Pressure Pump with Venturi Impeller & Pressure Manager

The Onga JSP90 combines the proven performance of the Italian-made JS Series self-priming jet pump with the convenience of an integrated Pressure Manager for fully automatic operation. Designed for reliable water supply and high suction lift performance, it features a corrosion-resistant 304 stainless steel pump casing, precision-moulded jet, venturi, and impeller for maximum efficiency.

The Pressure Manager automatically starts and stops the pump on demand, maintains constant pressure, and includes run-dry protection—making it ideal for domestic water supply, small-scale irrigation, and general water transfer applications.
