The types and working principles of self-priming pump

It is no need to irrigation before operation when the self-priming pump was first irrigation inside the pump. After a short run, it will be able to beat the air inlet pipe and the water sucked up, than into normal operation. Self-priming pump does not need other auxiliary facilities such as a variety of vacuum devices or foot valve. Suck it up specifically refers to the internal structure by changing the pump itself which self- priming centrifugal pump has evacuated the ability.
Self-priming pump and centrifugal pump works similar, centrifugal pump also has some mixed transportation capacity. In order to achieve vacuum, self-priming pump uses centrifugal pump principle which adopts special structure to make liquid and gas mixed. So that the inlet pipe to reach vacuum will suck the liquid inlet tube on purpose. It is based on liquid and gas mixing in different positions in the self-priming pump.
Self-priming pump types can be divided into inner and outer mixed style, according to the characteristics and material, it divides into stainless steel self priming pump and engine self priming pump. Liquid flow back into the impeller inlet, gas and liquid at the impeller mixed population known as the mixed-type self-priming pump. Liquid flow back into the impeller outlet, gas and liquid mixture outer edge of the impeller is called the outer self priming pump.
