A rotary vane vacuum pump is an oil-sealed rotary displacement pump. The pumping system
consists of a housing (1), an eccentrically installed rotor (2), vanes that move radially under spring
pressure (3) and the inlet and wall plug (4). The wall plug valve is usually oil-sealed. The inlet valve was created as a
vacuum safety valve that’s always open during operation. The working chamber (5) is situated
inside the housing. Rotor and vanes divide the functioning chamber into two separate spaces having
adjustable volumes. As the rotor turns, gas flows into the enlarging suction chamber until it is sealed
off by the second vane. The enclosed gas is Rotary Vane Vacuum Pump definitely compressed until the outlet valve opens against
atmospheric pressure. Regarding gas ballast operation, a hole to the exterior is opened, which
empties in to the sealed suction chamber on leading side.
The Rotor moves by making use of a motor attached to it.
