Description
The RV1P are variable displacement vane pumps, with pilot-operated hydraulic pressure compensator, which allow the delivered flow rate to be instantly adjusted according to the circuit requests. Energy consumption is reduced and adequate at every moment of the cycle. The pumps have dual internal delivery and suction lines. The pumping group is equipped with double hydrostatic axial compensation which improves the volumetric efficiency and reduces the wear of the components. The pressure compensator keeps the stator ring of the pumping unit in an eccentric position by means of the action of a piston controlled hydraulically by a pressure pilot stage. When the delivery pressure equals the pressure corresponding to the pilot stage setting, the stator ring is moved towards the centre, adjusting the delivered flow rate to the values required by the system. In conditions of zero required flow, the pump delivers oil only to compensate for any leakage and piloting, keeping the pressure in the circuit constant The response times of the compensator are very limited and such as to allow the elimination of the maximum pressure relief valve Available with direction of rotation clockwise, with rectangular flange and tapered shaft with key or with ISO 3019/2 flange and cylindrical shaft with key. This pump is available with a regulator for one or two pressure stages. keeping the pressure in the circuit constant The response times of the compensator are very limited and such as to allow the elimination of the maximum pressure relief valve Available with clockwise rotation, with rectangular flange and tapered shaft with key or with ISO 3019/2 flange and cylindrical shaft with key.
