PSV-PSSF-10HRM-56

The PSV-PSSF-10HRM-56 belongs to the PSV Variable Vane Pumps series from Bosch Rexroth and is used to supply regulated hydraulic flow in automated machinery. It employs a variable volume vane design so the displacement decreases automatically as demand falls, limiting wasted energy. A pressure compensator acts as the primary control element, reducing output once system pressure nears the set point to prevent overload. Flow can be trimmed with a screw volume control that lets maintenance staff match delivery to circuit requirements. The unit handles working pressures up to 2000 psi, making it appropriate for medium-pressure tool clamps and indexing tables. A right-hand rotation shaft aligns with standard electric motor drives for straightforward coupling.

The pump incorporates a two-stage compensator that initiates a small pilot response before engaging the main spool, producing smoother pressure transitions during rapid load changes. Subplate mounting lets the housing bolt directly to a manifold surface, which speeds removal and eliminates external piping between pump and valve stack. Viton seals withstand elevated oil temperature and resist swelling in petroleum-based fluids, preserving internal clearances over long service intervals. These construction choices maintain consistent volumetric efficiency when the pump is cycled repeatedly in automated presses or plastic molding lines. Overall, the combination of staged pressure control, modular mounting, and durable sealing supports reliable hydraulic automation with minimal maintenance downtime.
