Onga JSP45 0.37kW Self-Priming 304 Stainless Steel Pressure Pump with Venturi Impeller & Pressure Manager

The Onga JSP45 is a compact, Italian-made self-priming jet pump designed for reliable, automatic water supply in domestic applications. Combining a durable 304 stainless steel pump casing with a precision-moulded jet, venturi, and impeller, it delivers consistent performance, even with high suction lifts.

Fitted with an integrated pressure manager, the JSP45 automatically starts and stops the pump on demand while providing loss-of-prime protection for added safety. Its stainless steel base keeps the pump elevated above corrosive surfaces, ensuring long-lasting service life.
