Self Priming Cetrifugal Pump

Efficient Engineers now introduce self priming centrifugal pump with closed and semi open impeller .
We have made ss-304 or ss-316 chamber in round shape or in square shape .
These chambers are interconnected with casings , casings have flap type or disc type non return valve (NRV) depend upon application . we use flap type NRV when liquid is dirty or containing some solid particles . We use disc type check valve when liquid is crystal clear.
These NRVs hold liquid in the chamber and centrifugal pump work as self priming pump.
All wetted parts are made from ss-304 or ss-316 sheet only and chambers are tested with hydraulic test up to 10 bar . If pressure is more , then we test at 1.5 times then shutoff pressure . Thickness of sheet depend upon size and pressure of system .
These pumps are ideal for all application where people do not want to use footvalve and have suction problem .
Size of self priming chamber depend upon capacity and suction length . we also offer openable chamber so one can clean it very easily. This is required in sanitary application and in some sticky material application .
All our CF series pumps are now available with such chamber in monoblock or bare version.
All our mud pumps which is very costly in SS castings are now offered in our new SPCF version with open or semi open impellers .
