The PSV20/SV10 6974012 62 pump belongs to the PSV Variable Vane Pumps series and is manufactured by Bosch Rexroth for hydraulic automation that requires an adjustable, steady flow source. At 1800 rpm the main section outputs 56.8 L/min, providing sufficient volume for mid-range actuator circuits, while a maximum main pressure of 138 bar keeps the unit within common line ratings. A theoretical displacement of 32.8 cm³ per revolution defines how much fluid is moved each shaft turn and guides drive motor selection. Continuous service is permitted up to 1800 rpm so the pump can couple directly to standard electric motors. Right-hand rotation specifies installation orientation, and a Viton seal resists heat and petroleum-based fluids encountered in industrial systems.
For auxiliary functions the pump supplies 7.5 gpm at 1800 rpm, creating a secondary flow path for pilot controls or lubrication circuits. The auxiliary outlet can be pressurized to 2000 psi, enabling independent control loops without affecting the main channel. Case pressure is limited to 0.7 bar, so the drain line must return with minimal backpressure, and an inlet vacuum limit of 152 mmHg helps prevent cavitation when the reservoir is below pump level. The thru-shaft transfers up to 15 kW, allowing tandem mounting of additional pumps or accessories. A return filter rated at 10 µm is recommended to protect the internal vanes from particle wear during continuous duty.
