Rotary vane vacuum pump mainly consists of pump body, rotor, rotary vane, end cap, oil tank and so on. A rotor with three vanes is mounted eccentrically in a cylindrical housing, the three vanes slide in the rotor slots. When rotating, the centrifugal force keeps the vanes in contact with the housing and the rotation drives the rotor to slide along the housing.

The diagram below shows the structure of the pump. When the rotor rotates, the vanes, the housing and the two end caps form three chambers, every turn, the volume of each chamber increases or decreases due to the sliding of the vanes, completing the suction and discharge process.
The rotary vane vacuum pump is suitable for the applications where the requirement of vacuum is not high and the operation is reliable and maintenance is convenient. It is commonly used in vacuum packaging of various foodstuffs, vacuum forming of rubber and plastic industry, paper transmission of printing industry, vacuum impregnation and leakage prevention of various castings, vacuum fixture, vacuum drying, vacuum filtration, and hospital surgery.
