Installation and Application
These pumps are self-priming centrifugal 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 pump body by two pipes. The total delivery produced by the closed centrifugal impeller is sent only partly to the delivery opening, the remaining 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.
Those pumps should be installed in a covered area, protected against the weather.
