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 PVE pumps are variable displacement vane pumps with direct pressure regulator.

The pump group is complete with hydrostatic axial compensation distribution plates that improve the volumetric efficiency and reduce wear of the components.
The pressure regulator adjustable load spring keeps the pump group cam ring in eccentric position. When the delivery pressure equals the pressure corresponding to the spring setting, the cam ring is moved so to reduce the displacement, adjusting the flow rate to the values required by the plant. In zero flow demand conditions, the pump delivers oil only to compensate any possible bleedings, keeping the circuit pressure constant.
The PVE pumps are available in four dimensions with maximum displacement from 6,6 to 22,2 cm³/rev and with pressure regulator max setting values up to 35 bar and 70 bar (standard).
