PVB45A FRSFX 10 C

The PVB45A FRSFX 10 C piston pump belongs to the PVB Piston Pumps series produced by Vickers. It serves as a variable-displacement source for hydraulic automation circuits that need stable flow under changing load. The displacement is 5.76 in³ per revolution, so every rotation delivers that volume of oil to the system. Because the displacement type is variable, the pump can adjust output to match demand, and the displacement zone is limited to one side of center to maintain controlled swash-plate travel. A pressure compensator marked “C” governs the swash-plate angle to hold downstream pressure within a preset limit. During operation the unit reaches a nominal flow of 45.0 gpm, supporting mid-size actuator groups. Clockwise rotation matches right-hand drive arrangements, a maximum speed of 3000 rpm permits direct coupling to standard electric motors, and power is transmitted through a 1.75-inch shaft diameter that fits common keyed couplings.

The pump weighs 211 lb (96 kg), allowing installation with conventional shop hoists without exceeding manual handling thresholds. A flange mount pattern aligns the housing to pump pads on industrial power units, and side ports keep hose bends short inside compact reservoirs. The inlet connection uses a 2-inch flange, providing low restriction for the suction line, while the case drain exits through an SAE-12 port to return leakage oil and balance internal pressure. Discharge pressure can be driven as high as 3000 psi (210 bar), enabling the unit to supply cylinders or motors that operate at standard system pressures. These hydraulic and mechanical interfaces create a self-contained pump suited to automated machinery that requires reliable variable flow with compact side-port plumbing.
