The PVQ32-B2R-SE1S-21-CGD-30 piston pump is built by Vickers within the PVQ Piston Pumps series for closed-loop hydraulic automation. It delivers a displacement of 32.9 cm³ per revolution so circuit designers can size flow exactly to actuator demand. A hydraulic remote pressure compensator adjusts the swashplate to keep system pressure stable under varying load. The unit operates continuously at 140 bar rated pressure and reaches 1800 rpm rated speed, parameters that match mid-range industrial power packs. A maximum input power of 15.6 kW defines the motor size required for efficient drive coupling. Power is transferred through a straight keyed SAE B input shaft, and the housing mounts on an SAE J744 101-2 flange to fit standard B-frame adapters. Right-hand clockwise rotation aligns with common engine-to-pump layouts in mobile machinery.
Fluid connections are placed on the rear face with SAE O-ring ports; both the inlet and outlet measure 1.625 inches to simplify hose selection and reduce inventory. The case drain is limited to 0.35 bar maximum, protecting shaft seals and preventing oil aeration. An adjustable maximum-displacement stop lets maintenance personnel cap flow when applications call for fixed throttling or power savings. Internal sealing surfaces use Nitrile (Buna-N) material, enabling compatibility with conventional petroleum-based hydraulic oils. Because no through-drive is provided, the pump must terminate the shaft line rather than cascade multiple units. Overall mass is 14 kg, light enough for bracket mounting on mobile equipment yet sturdy for stationary manifolds.
