PSV-SSSF-25ERM-110/115-56

The PSV-SSSF-25ERM-110/115-56 pump is produced by Bosch Rexroth within the PSV Variable Vane Pumps series. It supplies adjustable hydraulic flow for automated machinery where pressure staging is required. A solenoid two-pressure control shifts the displacement between two preset pressure levels to suit changing load conditions. When driven at 1800 rpm the unit delivers 20.2 gallons per minute, providing stable circuit flow for medium-duty actuators. The internal cartridge uses a variable volume vane mechanism to vary displacement without interrupting operation, and a subplate mounting interface allows rapid removal from manifolds for service. The housing sustains continuous operation at 1000 psi so cylinders and motors receive consistent pressure without overload.

Right-hand rotation aligns with standard clockwise prime movers, simplifying coupling to electric motors on common power units. A Viton seal set resists mineral oil and higher temperature fluids, extending service life in installations that cycle frequently. Output volume can be trimmed with a screw adjustment so technicians can fine-tune actuator speed on site. These features complete the hydraulic package by matching rotation, sealing, and manual volume control to the electronic two-pressure shift described earlier, giving installers a unified pump that supports flexible automation tasks.
