PSV-PSCF-40HRM-66

The PSV-PSCF-40HRM-66 variable vane pump belongs to the PSV Variable Vane Pumps series from Bosch Rexroth. The unit supplies pressurized fluid to hydraulic actuators in automated lines where adjustable flow and compact build are required. As a vane pump, it delivers smooth flow with low pulsation. Its pressure compensator control mode automatically trims displacement to maintain a target line pressure. At 1750 rpm the rated flow is 30 GPM (113.6 L/min), supporting medium-capacity circuits. The design withstands a maximum operating pressure of 2000 psi (138 bar) so it can serve moderate-pressure tooling and clamping systems. Right-hand rotation ensures correct drive alignment when the shaft is viewed from the coupling end.

For installation, the PSV-PSCF-40HRM-66 is flange mounted, giving precise shaft concentricity when paired with a C-face motor bracket. Both suction and pressure passages rely on a flange connection, and the housing is side ported so hoses exit laterally and clear overlying frames. A screw-adjust volume control allows technicians to set maximum displacement with a single turn, matching pump output to varying load demands without electrical interfaces. Viton seals provide resistance to mineral oil and elevated temperatures, helping the pump retain leakage control during extended duty cycles. These mechanical features simplify maintenance and improve reliability in hydraulic automation stations.
