PUMP INSTALLATION AND APPLICATIONS
The series 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 to the delivery opening.The remaining(driving) water it recirculated through the ejector,which is connected to the suction chamber where is 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 recirculation water from the pump,thus increasing its pressure at the expense of the recirculation water,and is the diffuser with recirculatin 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.
