JETDP series Self-priming Deep Well Pump

JETDP series Self-priming Deep Well Pump

JETDP series pump is suitable for 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 the pump body with two pipes. The whole delivery produced by the closed centrifugal impeller is sent only with the delivery opening. The remaining (driving) water is re-circulated 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 re-circulating water from the pump, thus increasing its pressure at the expense of the re-circulating water, and it is drawn into the pump through the suction pipe.
