Self-priming centrifugal pump

Self-priming pumps rely on the special structure of its own self-priming effect arising from a single- stage single-suction www.dongfeng-motor.com centrifugal pumps , self-priming centrifugal pump is called . Compared to ordinary centrifugal pumps , there is significant difference between the pump body structure : First, improve the pumps position of the pump inlet , sometimes fitted with suction valve ; Second, in the water diesel generating set side of a gas-water separation chamber .Pump outside the pump, plus there is a self-priming pump devices, such as with a vortex pump , water ring vacuum pumps, jet pumps and hand pumps.

Compared with ordinary self-priming centrifugal pump , with a compact , easy to use operation , not only eliminates the need for a large number of irrigation water before starting the trouble , but also eliminates the need 12 volt motor for low inlet valve , reducing water resistance, increased pumping capacity However, compared with ordinary centrifugal pump efficiency with lower specifications of 3% to 5 %. Self-priming pump more is applied to the light and small units and pipe sprinkler irrigation unit.
