DVP Oil Free Dry Running Rotary Vane Pressure Pumps

Working Principle Rotary Vane Pumps operate with a eccentrically mounted rotor within the pump body. The rotor has slots that accommodate the vane.  Under power the vanes are centrifugally pushed out forming a seal against the pump body, creating chambers of air.  As the eccentric rotor spins, this creates a pressure which can be used as a vacuum pump or a compressor. All of the DVP oil free dry running rotary vane pressure pumps from Vacuum Pumps UK may run continuously within certain pressure ranges, or connected to containers to be emptied, whose volume is appropriately sized for the pump flow rate. Long-term use at atmospheric pressure is not recommended. The self lubrication of the carbon vane avoids the need for oil lubrication. Dry running compressor pumps cannot be used when the aspirated air contains moisture, oil or other traces of liquid.
