Duplomatic RV1P Vane Pumps
Duplomatic RV1P pumps are variable displacement vane pumps. They have a hydraulically operated pressure compensator that allows flow rates to be adjusted instantaneously to meet the circuit’s requirements. Volumetric efficiency is improved and wear on components is reduced. Both internal paths for inlet and outlet are double.
The pressure compensator keeps the pumping group cam ring in the eccentric position by a hydraulically controlled piston. When the delivery pressure equals the pilot stage setting pressure, the cam ring is moved toward the centre, adjusting the flow rate to the equipment requirements. In zero flow demand conditions, the pump only delivers oil to compensate for any possible leakages, keeping the circuit pressure constant.
The compensator response times are very restrained and allow the pressure relief valve to be removed.
RV1P pumps are available in 10 sizes with displacements from 16 to 120 cc/rev: RV1P-016 | RV1P-020 | RV1P-025 | RV1P-032 | RV1P-040 | RV1P-050 | RV1P-063 | RV1P-080 | RV1P-100 | RV1P-120
Flow rates at 1500 rpm range from 25.5 litres/minute to 184.5 litres/minute. Maximum operating pressure ranges from 210 to 250 bar.
