The PVQ13-A2R-SE1S-20-C14-12-S2 pump belongs to the PVQ Piston Pumps series produced by Vickers for closed-loop hydraulic automation where compact variable displacement units are required. Its displacement of 13.8 cm³ per revolution establishes the base flow rate that the circuit can expect at the rated speed of 1800 r/min, allowing predictable actuator velocity. A maximum working pressure of 140 bar confines system loading, while the 6.5 kW input power at that pressure defines the drive motor size. The compensator is factory set to 138 bar so the swashplate reduces stroke just below the full pressure limit to prevent energy waste. An inlet pressure window from 5 in Hg vacuum to 2 bar protects the pump from cavitation and excessive suction head. Right-hand clockwise rotation identifies the shaft orientation when planning engine or electric motor coupling. The SAE J744 82-2 mounting flange standardizes the mechanical interface with common A-frame drives.
The shaft measures 0.75 in in diameter and 1.75 in in length, giving designers the exact coupling dimensions for a keyed or spline adapter. SAE O-ring rear ports simplify manifold plumbing by using straight-thread connections that seal on the elastomer. A .562-18 UN-2B case drain thread provides a dedicated return path for leakage oil back to the reservoir. The case pressure limit of 0.35 bar safeguards internal seals from overloading when the drain line is restricted. Buna-N sealing material offers compatibility with petroleum-based hydraulic fluids at typical operating temperatures. An onstroke response time of 0.048 s indicates how rapidly full displacement is achieved after a load demand, and the offstroke response of 0.016 s shows how quickly the pump unloads for energy conservation. An overall mass of 7.2 kg supports mounting on small power units without excessive structural reinforcement.
