Jet self-priming NGL pumps
Design
Self-priming monoblock centrifugal pump with built-in ejector.
Application
Water supply from wells.
For lifting water containing air or other gases.
To increase the pressure of water supplied to the pump
by gravity when operating under hydraulic pressure.
To increase the pressure of water from the distribution network (observe local regulations).
For clean water or lightly soiled surfaces.
Use in garden areas.
For washing with a strong water jet.
Operating restrictions
