PVQ10-A2R-SS1S-20-CM7-12

The PVQ10-A2R-SS1S-20-CM7-12 piston pump belongs to the PVQ Piston Pumps series manufactured by Vickers and supplies variable displacement flow for hydraulic automation loops. Its displacement of 10.5 cm³ per revolution establishes the volume moved each shaft turn, giving engineers a clear basis for sizing circuits. A rated pressure limit of 210 bar lets the pump support typical actuator loads encountered in mobile and industrial systems. The built-in low-pressure compensator (CM) starts to reduce swashplate angle at 69 bar (1000 psi), preventing pressure overshoot in relief-sensitive valves. Maximum input power is 7.4 kW, so prime movers can be matched without excess capacity or wasted energy. Right-hand clockwise rotation aligns with standard engine or motor outputs, and the SAE J744 82-2 mounting flange fits directly to an SAE A housing for straightforward installation. A weight of 7.2 kg allows a single technician to mount or remove the unit without lift assistance.

Case drain pressure must stay below 0.35 bar to avoid stressing the shaft seal, so the return line should flow unobstructed to tank. The pump tolerates inlet pressure up to 2 bar for flooded suction arrangements, while an inlet vacuum limit of 0.2 bar vacuum defines the maximum vertical lift when the reservoir is below the pump. Side ports that use SAE O-ring connections in a 1.3125-inch size simplify hose routing and ensure leak-tight joints under cyclic loads. Buna-N seal material is chosen for compatibility with conventional petroleum-based hydraulic fluids. A sound level of 71 dB informs enclosure design and operator exposure planning when multiple pumps run in the same area. These operating limits and interface details help the PVQ10-A2R-SS1S-20-CM7-12 deliver stable, low-noise service in equipment that requires dependable pressure regulation and compact packaging.
