WORKING PRINCIPLE: The series are SELF-PRIMING CENTRIFUGAL PUMPS, self-priming is achieved using an ejector, housed in the pump body. The totally delivery produced by the closed centrifugal impeller is sent only partly to the delivery opending, the remaining water is recirculated through the ejector, which is connected to the suction chamber and generates the necessary vacuum to self-priming the pump.
