Rotary Vane Vacuum Pump

Singel-stage rotary van vacuum pump Rotary Vane Vacuum Pump eco-friendly Vacuum Pump Basic Principle The sucking and exhausting valves are usually fitted in the round pump body where there is a centrifugal rotor with three vanes that is driven by centrifugal power. Through the three vanes, the inner space of vacuum pump is split into three parts, whose respective volumes will change periodically as the rotor rotates. With the cavity volume changes, the sucking, compressing
