WONCHANG Vacuum Pump

Wonchang’s Oil Sealed Rotart Vane Pump operates according to the rotary vane principal. The rotor is eccentrically positioned in the pump cylinder and has machined slots for sliding vanes. The centrifugal force of the rotation pushed vanes out these slots and towards the wall of the cylinder. The gas enters the vacuum pump inlet then passes through a built-in antisuck back valve that prevents the pump from rotating backwards and into the cylinder. The gas is compressed and pushed out through the exhaust opening located between the pump housing and exhaust box. The oil is feeding consistently to cylinder from oil sump for sealing and lubrication, and collects through oil exhaust filter in the bottom of the oil exhaust separator chamber and returns to the oil sump.
