Self-priming pump with Pedrollo ejector JDWm1Ax-30-4

Pedrollo JDWm1Ax-30-4 is a high‐efficiency self‐priming pump with an ejector, specifically engineered for drawing water from wells up to 45 meters deep. Utilizing the Venturi principle, the pump creates a stable vacuum in the suction line, enabling reliable operation when installed above ground. It’s perfect for domestic tasks such as supplying water from deep wells, automatic home water systems, or drip irrigation.

Operating Principle

The pump features a built‐in ejector assembly with a Venturi tube. A portion of the water delivered by the impeller is recirculated back into the suction chamber. This recirculation generates the vacuum needed to lift water from the well. The incoming deep‐well water mixes with the recirculated fluid, increases its pressure, and is then discharged through the delivery port. This design allows pumping from depths far exceeding the standard 9 meters.
