DFP Fixed Displacement Vane Pumps
The DFP and DFDP pumps are fixed displacement vane pumps, made in four different sizes, divided in turn into five nominal displacement sizes. They are available as single pump or double pump.
Description
The DFP and DFDP pumps are fixed displacement vane pumps, made in four different sizes, divided in turn into five nominal displacement sizes. They are available as single pump or double pump.
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.
