Rotary vane vacuum pump EV series

lubricatedsingle-stagecompact

The EV-series are robust vacuum pump for industrial use. Eurovacuum EV-series pumps are Oil Recirculation, Single Stage, Air-Cooled and Direct Driven. They are compact in design- Reliable & Durable- Easy to maintain and operate. Easy installation due to air-cooling without any cooling water requirements. The pumps are direct driven, so they do not require belts. With the integral exhaust filter unit the discharged Air is 99,9% oil free and quite in operation. Operating principle The Oil Sealed Rotary 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 anti-suck 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 pump.
