PSV-SNRF-40HRM-66-110/115

The PSV-SNRF-40HRM-66-110/115 pump is made by Bosch Rexroth for the PSV Variable Vane Pumps series. It serves hydraulic automation loops by supplying adjustable oil flow to actuators. The unit is a variable volume vane type, so displacement adapts to load changes. Its solenoid two-pressure control switches automatically between two preset pressure stages to improve efficiency. At 1750 rpm the pump provides a nominal flow of 30 GPM, supporting medium-speed cylinder motion. A maximum operating pressure rating of 2000 PSI allows reliable work in moderate-pressure machines, and the assembly is configured for right-hand rotation to pair with standard clockwise drive shafts.

The model attaches directly to a prime mover with flange mounting, maintaining shaft concentricity and reducing coupling wear. Hydraulic lines couple through a flange connection, and the rear-ported layout directs hoses straight back for compact cabinet routing and easier service access. Viton seals contain the fluid and withstand the elevated temperatures typical of industrial hydraulic oils. Because the design includes no independent volume control mechanism, external regulators are unnecessary, which lowers component count and fault risk. These installation features simplify plumbing while preserving rigidity, supporting dependable operation in presses, test stands, and general industrial equipment.
