HP P2 Series Pumps
Variable Displacement Closed Circuit Axial Piston Pumps, Displacement 14 to 23 cm³ (0,85 to 1,40 in³), (Swashplate 14,5 | 19 | & 18), Continuous 250 bar (3625 psi), Pressure Intermittent 280 bar (4060 psi), (Power-Transmission Hydrostatic Transmission).
The axial piston pumps series HP P2 is designed to operate in a closed circuit.
Control Systems are available making it easy to use these pumps in any application in the industrial and mobile field.
Typically the pump HP P2 is equipped with bronze bearings for hydrostatic suspension of the swashplate. Alternatively, there are roller bearings for the swashplate suspension available on request.
Development of rotating groups, especially designed, united to an accurate study of oil passage sections, allow high-speed rotation, like required by modern diesel engines, giving extreme reliability for working continuous pressure until 250 bar and working peak pressure until 350 bar.
It is possible to couple tandem versions, by means of coupling flanges optionally available.
Closed circuit axial piston pumps are used as hydrostatic transmission components in self-propelled machines and for rotary drives in both fixed and mobile equipment of all kinds.
