PSV-PSAF-20HRM-66

The PSV-PSAF-20HRM-66 pump belongs to the PSV Variable Vane Pumps series from Bosch Rexroth and supplies pressurized fluid for hydraulic automation circuits. It is a variable volume vane design, so the displacement can be altered to match load demands. A flow rate of 15.2 GPM at 1800 rpm supports medium-size machine tools and assembly equipment. The unit tolerates system pressures up to 2000 psi, enabling it to drive cylinders and motors without external boosters. A standard pressure compensator adjusts the vane geometry to hold the target pressure while minimizing energy loss. Right-hand rotation matches most electric motor drives, and a flange-mounted housing provides rigid alignment with the prime mover.

Side ports with SAE threaded connections simplify hose routing and keep the pump close to the reservoir wall. A Viton seal set withstands mineral oils and elevated operating temperatures, extending service life between maintenance intervals. Volume is trimmed with a screw-type control that lets technicians fine-tune flow without removing the pump from service. These port and control features complement the pressure compensator to maintain stable output under shifting loads. The overall configuration delivers compact installation, straightforward adjustment, and leak-resistant operation for automated hydraulic stations.
