PSV-PNCF-20HRM-56

The PSV-PNCF-20HRM-56 pump belongs to the PSV Variable Vane Pumps series and is manufactured by Bosch Rexroth for hydraulic automation systems that need consistent flow and pressure control. It employs a variable-volume vane mechanism that alters vane position to match demand and limit wasted energy. A pressure compensator maintains outlet pressure, allowing the unit to adapt to load changes without external sensors. The housing tolerates 2000 PSI, making the pump suitable for medium-pressure circuits. At 1800 rpm it provides 15.2 GPM, offering predictable actuator speed. The shaft turns right-hand, ensuring compatibility with standard motor couplings used in industrial power packs.

Integration is simplified by flange mounting, and each hydraulic interface uses a 4-bolt flange that resists loosening under pressure pulses. Side ports position suction and discharge lines along the housing, helping designers keep piping compact inside power units. Viton seals isolate the working fluid and withstand elevated oil temperature as well as common additives. The design includes no external volume control, so displacement is set by the internal mechanism and requires no field adjustment. These features support stable operation when the pump is applied in automated clamping, molding, or indexing equipment.
