PSV-PNCF-25ERM-66

The PSV-PNCF-25ERM-66 pump belongs to the PSV Variable Vane Pumps series and is manufactured by Bosch Rexroth to deliver regulated hydraulic flow in automated machinery. A pressure compensator maintains output when load pressure fluctuates, preventing wasted drive power. The unit supplies 20.2 GPM at 1800 rpm, providing adequate flow for medium-capacity cylinders and motors. Its 1000 psi pressure rating defines the continuous working limit for downstream components. Right-hand rotation aligns with most clockwise prime movers, and flange mounting holds the housing rigidly against the drive interface. Side ports keep hoses parallel to the body so the pump fits into compact power units without excessive bends.

Fluid enters through a 1.5-inch four-bolt inlet flange and exits through a 1.0-inch four-bolt outlet flange, allowing straightforward line sizing between suction and pressure sides. The shared four-bolt port connection pattern speeds assembly and ensures repeatable gasket compression. Viton seals tolerate high-temperature petroleum and synthetic oils to extend maintenance intervals. Because the design includes no volume control, flow adjustment relies on drive speed and the compensator rather than an external knob or lever. These features combine to make the PSV-PNCF-25ERM-66 a stable source of pressurized oil for presses, test rigs, and machining centers.
