The PVQ32 B2R SE1S 10 C14 11 variable piston pump belongs to the PVQ Piston Pumps series from Vickers and delivers regulated hydraulic flow for automated machinery. Its displacement of 32.9 cm³ per revolution defines the volume moved with each shaft turn and therefore the base flow rate. A pressure compensator control maintains system pressure without external valving. The pump tolerates up to 140 bar, establishing the maximum working load, and it draws 15.6 kW at that limit, setting the required prime-mover capacity. A rated speed of 1800 r/min indicates the intended drive speed, while right-hand clockwise rotation specifies the correct orientation when coupling to a motor. An SAE J744 101-2 (SAE B) mounting flange provides a standardized housing interface, and rear SAE O-ring ports with 1.625-inch inlet and outlet simplify hose selection.
The unit weighs 14 kg, a figure important when assessing bracket strength and manual handling during maintenance. A shaft length of 2.31 inches establishes the distance available for coupling engagement and ensures proper spline contact. Buna-N seals are fitted to resist petroleum-based fluids and maintain leakage control over time. The inlet can accept up to 2 bar, preventing aeration when a boost charge circuit is used, and a maximum inlet vacuum of 0.2 bar limits suction lift to protect against cavitation during rapid demand changes. Internal case pressure is restricted to 0.35 bar, guiding drain line design back to tank so housing seals remain unloaded. No thru-drive is provided, so the pump cannot pass mechanical power to an auxiliary unit in tandem arrangements.
