The PVB20RSW20CM11 piston pump is manufactured by Vickers for the PVB Piston Pumps series and delivers regulated hydraulic flow for industrial automation circuits. With a geometric displacement of 42.80 cm³ per revolution, the pump outputs a consistent volume each shaft turn to support predictable actuator movement. At 1800 r/min it achieves a rated flow of 75.7 L/min, supplying medium-capacity machines with steady oil delivery, while absorbing 29.4 kW of input power at 210 bar so prime movers can be sized correctly. A maximum operating pressure of 210 bar defines the safe limit for the circuit. The CM pressure compensator, set to 100 bar, adjusts the swashplate to stabilize outlet pressure and reduce energy loss when demand falls. Because the displacement control operates on one side of center, flow varies only in the positive direction. Clockwise shaft rotation together with a maximum speed of 1800 r/min aligns the unit with standard right-hand electric motor drives.
Installation uses a 17.5 mm bolt hole diameter that suits common fasteners, while a 127.00 mm mounting pilot diameter centers the housing for accurate alignment. A 31.75 mm shaft diameter matches many keyed or splined couplings to ensure dependable torque transfer. For right-hand rotation systems, oil enters through inlet port A and exits through outlet port B, streamlining hose routing. Both ports share a 1.625-12 UNF-2B straight thread, allowing standardized tube adapters and O-ring face seals. During operation at 1800 r/min and 210 bar, the acoustic emission reaches 81 dB(A), enabling planners to address sound control in enclosed spaces. These dimensional, connection, and noise characteristics facilitate straightforward integration of the PVB20RSW20CM11 pump into diverse hydraulic automation layouts.
