Contact SupplierPROMIVAC Rotary Vane Vacuum Pumps are single stage, oil lubricated vane type with inbuilt oil-circulation and anti-suckback system.The main assembly of the pump comprises of a dynamically balanced rotor with three or four specially treated fiber vanes which is mounted in a stator. When the rotor is made to rotate with the aid of the connected electric motor, these vanes move in & out of the slots by centrifugal force & slide against the walls of the stator pushing thereby the trapped air out of the stator & prompting the atmospheric air to gush in spontaneously to fill in the empty space.
