— 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).
See par. 16 ÷ ۲۱ for the combinations of double pumps.
— 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.
