PSV-PNSF-10HRM-56

The PSV-PNSF-10HRM-56 from Bosch Rexroth belongs to the PSV Variable Vane Pumps series and delivers regulated hydraulic power for automated machinery. A pressure-compensator control holds the outlet at a preset level so downstream actuators receive stable force without manual adjustment. With a nominal size of 10, the pump fits medium-capacity circuits while its displacement of 1.0 in³ per revolution (16 cm³/rev) defines the volume moved each shaft turn. At 1800 rpm and 100 psi the unit supplies 8 gpm (30.5 L/min), meeting the flow demand of typical industrial valves and cylinders. The right-hand clockwise rotation aligns with standard motor couplings, and a maximum drive speed of 1800 rpm permits direct coupling to common electric motors. Subplate mounting simplifies installation on manifold blocks, and the ability to mount in any position eases layout inside compact power units. Overall mass is 21 kg (46 lb), allowing single-person handling during maintenance.

A maximum system pressure of 2000 psi (138 bar) lets the pump support moderate-pressure tooling and clamping operations without overstressing components. Minimum inlet pressure is 0.8 bar absolute (11.6 psia), so the supply line must avoid excessive suction losses, while an allowable inlet vacuum of 6 inHg tolerates brief flow restrictions during start-up. Mineral oil and ester fluids are acceptable, giving users a choice between conventional and biodegradable media. Viton (FKM) seals resist heat and chemical attack from these oils, extending service life in continuous duty. The design includes no external volume control, meaning output is governed only by speed and pressure compensation, which reduces adjustment points in the field. These features combine to provide a compact, reliable source of pressurized flow for hydraulic automation circuits.
