DESCRIPTION

The HPR are variable displacement axial piston pumps, swash plate, for open circuit applications. They are available in seven sizes with nominal displacements from 55 to 280 cm3/rev. The flow rate delivered by the pump is proportional to the number of revolutions and to the angle of inclination of the oscillating plate. The maximum angle is limited mechanically by means of an adjustment screw. Thanks to the construction feautures, the HPR pumps are suitable for high operating pressures (420 bar continuous and 500 bar peak). All pumps are equipped with silencer in order to reduce noise emissions.
