All components subject to wear are contained within a replaceable cartridge which allows inspection and maintenance without disconnecting the pump from the circuit, thereby drastically reducing system down time. The cartridge consists of a rotor, vanes and inserts, a cam ring, two flexible plates and two covers. During operation the rotor is driven via a splined shaft coupled to the drive ring. As the rotational speed increases, centrifugal forces, combined with the pressure generated behind the vanes, extend the vanes outwards where they follow the profile of the cam ring with sufficient contact pressure to ensure adequate hydraulic sealing. The two opposed pumping chambers, formed by the elliptical profile of the cam, cancel out radial loads on the shaft bearings, thus giving extremely long working life. The vane pumps are designed to meet the requirements of the most varied industrial and mobile applications. In fact, as well as their proven high reliability and in all working conditions, they operate with particularly This is made excellent volumetric efficiency low noise levels. possible by the special profile of the cam ring and the use of a 12 vane rotor that reduces the amplitude of the supply pressure pulses, thereby reducing induced vibration.
