Bosch Rexroth PV7 pumps
Bosch Rexroth PV7 pumps
The PV7 type piloted vane pumps with variable displacement are characterized, from the construction point of view, by a reduced pulsation of the flow rate and achieve high repeatability accuracy with low pressure peaks, in case of regulation in decrease of flow rate. The optimization of the noise level on the screw with high variability guarantees a reduced operating noise level. Hydrodynamically lubricated plain bearings enable a long service life. The thruster axial compensation offers optimum volumetric efficiency.
