The PVQ13-A2R-SE1F-20-C14-12 pump belongs to the PVQ Piston Pumps series manufactured by Vickers for closed-loop hydraulic automation where compact variable delivery is required. It displaces 13.8 cm³ of fluid per revolution, setting the flow rate available to downstream actuators. A right-hand clockwise rotation suits engine or motor drives that follow standard SAE orientation, while the SAE J744 82-2 (SAE A) mounting flange lets the unit bolt directly to common power-take-off pads. The pressure-compensator control keeps outlet pressure constant; its factory compensator setting of 140 bar defines the point at which the swashplate begins to reduce stroke. With a maximum pressure rating of 140 bar the pump can run at its full set point without overstressing internal components, and it absorbs up to 6.5 kW at the rated speed of 1800 r/min, enabling predictable sizing of prime movers.
The compensator differential of 3.4 bar establishes the margin between cut-in and cut-out, ensuring prompt swashplate response to load changes. Case pressure must stay below 0.35 bar to prevent shaft-seal distress, and a fluorocarbon seal material is used to tolerate high oil temperatures and synthetic fluid blends. Fluid enters through a 1.0625 in SAE O-ring inlet port and exits through a matching 1.0625 in SAE O-ring outlet, both arranged as SAE O-ring rear ports so hoses can run straight back from the housing. This rear-port layout simplifies line routing inside compact power units and maintains consistent head conditions at the inlet during high-speed operation.
