Self-priming pump with Pedrollo ejector JDWm2-30-4

Pedrollo JDWm2-30-4 is a powerful and reliable self‐priming pump with an external ejector, specifically designed for drawing clean water from depths of up to 45 meters. Unlike conventional pumps, the JDWm2-30-4 can operate under low‐water conditions where standard pumps lose performance. It’s an excellent solution for homes, plots, and facilities located in areas with deep groundwater levels.

Operating Principle

The pump operates on the ejector principle, using the Venturi effect. Through two connecting ports, the pump recirculates part of the delivered water back into the ejector unit, creating a vacuum and enabling water intake from great depths. The water from the well mixes with the recirculated fluid, increases its pressure, and is discharged through the outlet.

Installation Recommendations

For stable operation, prefill the pipeline between the pump and ejector with water. A non‐return valve is mandatory on the ejector, and a safety valve is recommended at the outlet. The pump should be installed in a dry, ventilated, and weather‐protected location.
