What Are Vane Pumps? - North Ridge Pumps

2019-9-13  A vane pump is a self-priming positive displacement pump providing constant flow at varying pressures. Operation is via a motor connected to a gearbox as typically the maximum rpm is 900. The pump is fitted with a relief valve to prevent the pump from building to a pressure which may damage the pump.

Air Compressor - CAGI

2016-8-31  Rotary Sliding Vane Type The rotary vane compressor consists of a rotor mounted eccentrically in a housing (Figure 6). As the rotor turns, the vanes slide out by centrifugal force until they seal against a thin film of lubricant coating the stator wall. There is no metal-to-metal contact as the blade tip glides on the surface of the lubricant.
