The DFP pumps are fixed displacement vane pumps made in four different sizes, each size having five different nominal displacement. They are available with one pumping element (single pump) or with double pumping element (double pump).
— The FV6 pumps are fixed displacement vane pumps, with several nominal displacement each. Single, double and triple pumps are available.
— The pumping group is composed of a cartridge element that contains rotor, vanes, cam ring and support plates. Cartridges are easily removable without disconnecting the pump from the hydraulic circuit, thus simplifing the maintenance operations.
— The special elliptical profile of the cam ring, with double suction and delivery chambers one against the other, eliminates the radial thrusts on the rotor, reducing wear of the pump. The use of a 10 vane rotor reduces the delivery pressure pulsations, suppressing the vibrations and noise level of the pump.
— FV7BS e FV7DS pumps are single, double and triple fixed displacement vane pumps with different nominal displacements available.
— The pumping unit consists of a cartridge element, which contains the rotor, the vanes, the stator ring and the head disks. Cartridges are easily removable without the need to disconnect the hydraulic circuit pump, thus simplifying maintenance operation.
— They are available In various configurations, with clockwise or counterclockwise rotation, with fixing flange type SAE B, SAE C and SAE CC and with cylindrical keyed or splined shaft.
— The orientation of suction and delivery ports is widely open.
— The pressure compensator keeps the cam ring of the pumping group in the eccentric position with use of an adjustable load spring. When the delivery pressure equals the pressure corresponding to the spring setting, the cam ring is moved toward the center instantaneously, adjusting the flow rate to the values required by the plant.
— Energy consumption is reduced and adequate in every phase of the cycle.
— The pump group has hydrostatic axial compensation distribution plates, that improve the volumetric efficiency and reduce wear of the components.
— In zero flow demand conditions, the pump delivers fluid only to compensate any possible leaks and pilot lines, keeping constant the circuit pressure.
— The compensator response times are very low such as to make unnecessary the pressure relief valve.
New vane pumps PVE series 30. They are variable displacement vane pumps with direct pressure regulator.
Available in four dimensions with maximum displacement from 6,6 to 22,2 cm3/rev and with pressure regulator max setting values up to 35 bar and 70 bar (standard).
The PVE pumps are variable displacement vane pumps with direct pressure regulator.
— RV1P are variable displacement vane pumps with hydraulic operated pressure compensator, that permit instantaneous adjustment of the flow rate according to the circuit requirements. Energy consumption is reduced and adequate in every cycle phase.
— The pumping group is provided with double hydrosta ic axial compensation, that improves the volumetric efficiency and reduces wear of the components. Both internal paths for inlet and outlet are double.
— The pressure compensator operates keeping the cam ring of the pumping group in the eccentric position by a piston hydraulically controlled by a pressure pilot stage. When the delivery pressure equals the pressure corresponding to the pilot stage setting, the cam ring is moved toward the center, adjusting the flow rate to the plant requirements. In zero flow demand conditions, the pump delivers oil only to compensate any possible bleedings and pilotings, keeping the circuit pressure constant.
— The compensator response times are very restrained such as to allow the removal of the pressure relief valve.
