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. 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. This pump is available with a regulator for one or two pressure stages.

The RV1D are variable displacement vane pumps with mechanical pressure compensator.

The pressure compensator keeps the stator ring of the pumping unit in an eccentric position by means of an adjustable load spring: when the delivery pressure equals the pressure corresponding to the spring setting, the stator ring is moved towards the centre, instantly adjusting the delivered flow rate to the values ​​required by the plant. The pumping unit is equipped with distribution discs with hydrostatic axial compensation which improve its volumetric efficiency by reducing component wear.

The pumps are divided into four size groups, with displacements from 16 to 120 cm ³ /rev with operating pressures up to 120 bar. Available with clockwise rotation, with rectangular flange and tapered shaft with key or with ISO 3019/2 flange and cylindrical shaft with key.

The pumping group consists of a cartridge which contains the rotor, the vanes, the stator ring and the head discs. The cartridge is easily removable without having to disconnect the pump from the hydraulic circuit, thus simplifying maintenance operations. The particular elliptical profile of the stator ring, with double opposing suction and delivery chambers, eliminates the radial thrusts on the rotor, significantly reducing pump wear. The 12-blade rotor reduces the pulsations of the delivery pressure, limiting the vibrations and the noise of the pump.

They are characterized by a high volumetric efficiency, thanks to both radial and axial compensation proportional to the operating pressure, and by a low of noise. 

The optimal distribution of the loads and the particular bushing bearings allow to operate at high pressures in continuous operation and give the pump a long life. The IGP pumps are also available in multiple versions which can be combined in multi-flow groups.
