PSV-PNAF-15ERM-66

The PSV-PNAF-15ERM-66 pump is manufactured by Bosch Rexroth within the PSV Variable Vane Pumps series. It provides adjustable hydraulic flow for automation systems that require stable energy transfer. The unit uses a variable volume vane mechanism, allowing displacement to change with demand and improve efficiency. Installation is flange mounted to secure the housing directly to the drive motor. Hydraulic lines connect through side ports, and the interface threads conform to SAE standards for compatibility with common hose ends. Drive input is right-hand rotation, so the shaft turns clockwise when viewed from the motor end.

System pressure is managed by an internal pressure compensator that repositions the cam ring to hold a preset pressure without external controls. There is no separate volume control device, so flow modulation depends entirely on compensator action. Viton FKM seals are fitted to resist heat and aggressive hydraulic media during continuous duty. The pump can be combined in tandem with other units, enabling higher flow or multi-circuit arrangements when required. These features give the PSV-PNAF-15ERM-66 predictable pressure regulation and straightforward integration in industrial hydraulic automation.
