DESCRIPTION
The RV1P are variable displacement vane pumps, with pilot operated hydraulic pressure compensator, which instantly adjusts the flow rate according to the circuit requirements. Energy consumption is reduced and adequate at every moment of the cycle. Those vane pumps have internal supply and suction double ducts.The pumping unit is equipped with double hydrostatic axial compensation, which improves volumetric efficiency and reduces component wear. The pressure compensator keeps the stator ring of the pumping group in an eccentric position by means of a piston controlled hydraulically by a pressure pilot stage. When the delivery pressure equals the pressure set on the pilot stage, the stator ring moves towards the center, adjusting the flow rate delivered to the required values of the system. In condition of zero flow demand, the pump delivers oil only to compensate for any leaks and piloting, keeping the pressure constant in the circuit. The response times of the controller are very low and such as to allow the elimination of the pressure relief valve.
The gamma is made of four-dimensional groups, with displacements from 16 to 120 cm3/rev with operating pressures up to 250 bar, with clockwise rotation, with rectangular flange and tapered keyed shaft or with ISO 3019/2 flange and cylindrical keyed shaft. This pump is available with control for one or two pressure stages.
