Duplomatic DFP – Fixed Displacement Vane Pump

~ scroll down to find the part you need ~
Duplomatic Oleodinamica represents the real alternative in the hydraulics market.

Duplomatic’s wide range of products and worldwide service network, grant its users a real competitive advantage.

The Duplomatic 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 pumping group is composed of a cartridge type compact element that contains the rotor, the vanes, the cam ring and the head disks. The cartridge is easily removable without the need to disconnect the pump from the hydraulic circuit, thus simplifying 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, decisively reducing wear of the pump. In addition, the use of a 12-vane rotor reduces the delivery pressure pulsations, suppressing the vibrations and noise level of the pump.
