Portable Multistage Water Pump

The multistage pump is a kind of centrifugal pump which consists of the inlet and outlet section and the middle section. 

The output water pressure of the pump can be very large. When the gas density reaches the working range of the mechanical vacuum pump, it is drawn out, thus gradually obtaining a high vacuum. Multistage pump is by the pump chamber volume changes to achieve suction, compression and exhaust, so it can change the volume of the centrifugal pump.
