The PVQ40AR02AC10G21000001AA1APCD0A belongs to the PVQ Piston Pumps series from Vickers and serves as a variable-displacement axial piston unit for hydraulic automation. It displaces 2.500 in³ per revolution to generate the required flow, and at a rated speed of 1800 r/min it can accept up to 27.6 kW (37 hp) of input power. A built-in adjustable pressure compensator holds delivery pressure to 210 bar (3000 psi) so actuators receive stable force. The pump tolerates inlet pressures up to 2 bar (30 psig) and connects through a 1.500 in SAE code 61 four-bolt suction flange to minimize restriction. Discharge leaves through a matching 1.000 in SAE code 61 four-bolt outlet for straightforward circuit plumbing. A top-mounted .875-14 UNF O-ring drain port channels internal leakage back to tank, preventing excess case pressure.
The housing attaches with a 2-bolt B-B flange per SAE J744-101-2, simplifying direct mounting to standard drive pads. Torque is introduced through a 25.4 mm straight-key input shaft specified by SAE J744-25-1, while an auxiliary SAE A 9T 16/32 DP external spline permits through-drive of an additional pump. Right-hand (clockwise) rotation when viewed from the shaft end matches common engine outputs, and side-located main ports help keep hoses clear of adjacent components. Internal case pressure is limited to 0.35 bar (5 psig) to protect seals, with excess oil relieved via the dedicated drain path. The assembly weighs 20.6 kg (45.4 lb), allowing a single technician to position and secure the unit during installation.
