The PVER pumps are variable displacement vane pumps with direct pressure regulator governor spring for fast on/off response.

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 system. In zero flow demand conditions, the pump delivers oil only to compensate any possible leakage, keeping the circuit pressure constant.

The PVER pumps are available in four sizes with maximum displacement from 0.4 to 1.42 cu in/rev and with pressure regulator max setting values up to 500 PSI and 1000 PSI (standard).
