PSV-PNCF-80GRM-65

The PSV-PNCF-80GRM-65 is manufactured by Bosch Rexroth for the PSV Variable Vane Pumps series and is used to supply regulated flow in hydraulic automation circuits. It incorporates a variable-volume vane pumping element that allows displacement to adjust with system demand. A pressure compensator control limits outlet pressure without external electronics, maintaining stable operation in closed-loop machinery. Right-hand rotation defines the shaft direction for compatibility with standard engine couplings, and the housing is flange mounted to simplify alignment on power units. All fluid ports are positioned on the side, making hose routing straightforward in compact manifolds.

Fluid entry and return use a 4-bolt flange pattern that resists loosening under pulsating load. Viton seals withstand high-temperature petroleum oils common in industrial presses, extending maintenance intervals. The pumping cartridge contains a modified vane tip profile to reduce internal leakage at low speed. No external volume control devices are fitted, so displacement changes rely solely on the internal compensator described earlier. These design features match the pump to automated welding fixtures, injection molds, and other installations where constant pressure and compact mounting are required.
