PUMP INSTALLATION AND APPLICATIONS

The series are SELF-PRIMING CENTTIFUGAL PUMPS suitable for suction from deep wells, self-priming is achieved using an ejector, housed in the jet body, which can be installed directly on the pump body or more often lowered in a well and connected to the pumps body by two pipes. The total delivery produced by the closed centrifugal impeller is sent only to the delivery opening.

The remaining (driving) water is recirculated through the ejector, which is connected to the suction chamber where it generates the necessary vacuum to draw up water from the point where the jet body is immersed. The water from the jet body opening mixes in the diffuser with recirculating water from the pump, thus increasing its pressure at the expense of the recirculating water, and is drawn into the pump through the suction pipe.
