Rotary vane vacuum pumps are positive displacement pumps with vanes attached to a rotor that revolves inside a cavity. Under centrifugal and robust forces, the eccentrically positioned rotor vanes rotate radially, allowing air to be compressed under the pump chamber. A suction is then created to remove air molecules from a vessel or area.
At PumpAir Solutions, we choose from a variety of Gardner Denver Elmo Rietschle or Busch Rotary Vane vacuum pumps that cover a wide range of performance and can be dry running or lubricated based on process needs. PumpAir Solutions is a top-class supplier of air compression and vacuum products and is well-recognized for its cutting-edge technology and designs all over the world.

Working Principle of Rotary Vane Vacuum Pumps
The cylindrical housing of the rotary vane vacuum pumps has the rotor mounted eccentrically within. The working chamber is divided into two independent compartments by the vanes, each with a different volume. The centrifugal force applied pushes the vanes up against the cylindrical wall as it rotates, and hence, the inlet air is trapped between the rotor and the cylinder. As a result, the inlet port side of the cell increases in volume, hence, generating a vacuum. The chamber volume between the blades changes as the rotors revolve because of their eccentric positioning.
Air enters the chamber by the inlet when the chamber volume is larger, and when the chamber volume is lower, the air is compressed and pressure is produced at the outlet valve. The outlet valve of oil-lubricating rotary vane vacuum pumps is oil-sealed. A tiny quantity of oil enters the suction chamber when the valve is open, sealing the vanes against the chamber walls along with the lubrication.
