PSV-PSCF-20HRM-66

The PSV-PSCF-20HRM-66 is manufactured by Bosch Rexroth as part of the PSV Variable Vane Pumps series and serves hydraulic automation systems that require adjustable oil delivery. This variable volume vane design changes displacement in real time to match load demands and reduce wasted energy. At 1800 rpm the pump provides 15.2 gallons per minute, a flow level suited to mid-size cylinders and hydraulic motors. A standard pressure compensator limits outlet pressure to 2000 psi by repositioning the cam ring, protecting downstream components while keeping response times short. Right-hand shaft rotation matches common electric motor directions and simplifies coupling selection for maintenance teams.

Installation uses a four-bolt flange with side ports, so hoses can be routed straight into manifolds without sharp bends and the housing can be secured rigidly to machine frames. Displacement is trimmed with a set screw volume control, allowing service personnel to dial in flow without opening the casing. Viton seals isolate internal passages from external contaminants and tolerate elevated fluid temperatures, extending service intervals in continuous-duty stations. The compact flange pattern, side-port layout, and field-adjustable screw complete a package that integrates easily into automated presses, molding cells, and indexing machines where dependable variable flow is required.
