Pedrollo JSWm 1AX self-priming pump

Pedrollo JSWm 1AX is a reliable and compact self‐priming pump, designed for transferring clean water and non‐aggressive fluids in domestic water‐supply systems. Thanks to its built‐in ejector, the pump can self‐prime even when air is present in the suction line. The upgraded hydraulic design delivers enhanced efficiency and minimal noise, making it an excellent choice for homes, vacation properties, or small farms.

Operating Principle

The JSWm 1AX employs centrifugal technology with an ejector. On start‐up, the pump does not require pre‐filling of the suction pipe—simply add water to the casing. During operation, part of the pumped water is recirculated through the ejector, creating a vacuum that rapidly lifts water from the source. This system ensures reliable performance even with air in the fluid.
