PSV-SNCF-20HRMC-66-110/115-66

The PSV-SNCF-20HRMC-66-110/115-66 pump is part of the PSV Variable Vane Pumps series produced by Bosch Rexroth for hydraulic automation circuits that require stable yet adjustable flow. It uses a variable-volume vane design, so displacement changes automatically with system demand rather than staying fixed. A solenoid two-pressure control lets the pump switch between two preset pressure levels, giving machinery a simple way to alternate between work and standby modes. At 1800 rpm the unit delivers 15.2 gpm, a flow suitable for medium-size actuators and manifolds. The rated working limit of 2000 psi defines the maximum line pressure the housing and internal vanes can withstand. Right-hand rotation aligns the drive shaft with common electric-motor orientations, and the absence of separate volume control hardware reduces overall envelope size and simplifies maintenance.

The pump is flange mounted to provide a rigid interface with motor bell housings and to keep shaft alignment within tolerance during continuous duty. Inlet and outlet use a 4-bolt flange connection, giving technicians a standardized pattern for tightening and sealing the hydraulic lines. Side ports position both fittings on the pump flank, which helps keep hoses clear of framing members in compact power units. All dynamic seals are made from Viton, allowing reliable operation with typical petroleum oils and elevated fluid temperatures found in industrial presses and test stands.
