PSV-PSSF-10DRM-56

The PSV-PSSF-10DRM-56 pump belongs to the PSV Variable Vane Pumps series and is manufactured by Bosch Rexroth for hydraulic automation circuits that need adjustable flow without changing drive speed. Its displacement is 16 cm³ per revolution, so each shaft turn moves a fixed volume of oil that can be trimmed by the internal vane geometry. A flow rate of 30.5 L/min at 1800 rpm and 100 psi shows the output available under common plant conditions. The unit can begin operating at a minimum drive speed of 750 rpm, allowing low-speed machine startup, and it tolerates continuous service up to a maximum drive speed of 1800 rpm for higher throughput. These speed limits let designers pair the pump with electric or diesel prime movers across a practical speed range.

The hydraulic circuit can be set to a maximum system pressure of 138 bar, giving the pump enough headroom for medium-pressure tooling and clamping duties. An allowable inlet pressure window from 0.8 bar abs to 1.7 bar abs protects against cavitation while permitting flooded-suction arrangements. The pump can be mounted in any position, and its flange follows ISO 3019-1, so it fits standardized motor bell housings without adapters. Viewed from the shaft end, the rotation direction is right-hand, which guides alignment with couplings and drive shafts. A weight of 21 kg must be supported by the mounting hardware and influences lifting choices during installation.
