DESCRIPTION

The VPPM are variable displacement axial-piston pumps with variable swash plate, suitable for applications inside open circuits. They are available in three different frame sizes with maximum displacements up to 29, 46, 73 and 87 cm3/rev. The pump flow rate is proportional to the rotation speed and to the angle of the swash plate, which can be continuously modulated. The maximum and minimum angle can be limited mechanically by adjustment screws. The pumps work with medium-high pressures (up to 280 bar continuous and 350 bar peak). Thanks to some particular design features, these pumps are able to bear high axial and radial loads on the shaft. They are supplied with a ISO 3019/2 mounting flange, with the exception of the rear and intermediate pumps, if multiple pumps, which are only available with a SAE J744 2-holes flange and a SAE J744 splined shaft. They are available with seven types of controls.
