Duplomatic PVE Vane Pumps
Duplomatic PVE series 30 pumps are variable displacement vane pumps with a direct pressure regulator.
The pump group has hydrostatic axial compensation distribution plates that improve volumetric efficiency and reduce wear of components.
The pressure regulator adjustable load spring keeps the pump group cam ring in eccentric position. When the delivery pressure equals the spring setting pressure, the cam ring is moved to reduce the displacement – adjusting the flow rate to the values required by the equipment. In zero flow demand conditions, the pump only delivers oil to compensate for any possible leakage, keeping the circuit pressure constant.
PVE pumps are available in 4 frame sizes with displacements from 6.6 to 22.2 cc/rev: PVE-006 | PVE-011 | PVE-016 | PVE-023
Flow rates at 1500 rpm range from 10 litres/minute to 33.3 litres/minute. Operating pressure is 70 bar and rotation speeds range from a minimum 800 rpm to maximum 1800 rpm.
