The RV1D are variable displacement vane pumps with mechanical type pressure compensator.
The pressure compansator keeps the historical 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 center, instantly adjusting the flow rate deliveredto the values required by the system. The pumping unit is equipped with hydrostatic axial compensation distribution discs which improve the volumetric efficiency and reduce component wear.
They are divided into four dimensional groups, with displacements from 16 to 120 cm3/rev with operating pressures up to 120 bar, with clockwise rotation, rectangular flange with tapered keyed shaft end or with ISO 3019/2 flange with cylindrical keyed shaft-end.
This product replaces the PVD pump, now discontinued.
