The 4525V50A21 86CC22L vane pump is built by Vickers for the V Series Vane Pumps series and supplies pressurized fluid to hydraulic actuators in automated machinery. The unit operates with left-hand (counter-clockwise) rotation to match CCW drive shafts. At the front cartridge it displaces 162 cm³ per revolution, delivering 50 US gpm at 1200 rpm. The rear cartridge produces 67 cm³ per revolution and reaches 21 US gpm at the same speed. Continuous service is permitted down to 600 rpm, supporting low-speed circuits. Suction stability is maintained because the inlet port tolerates pressures from −0.17 bar to 1.4 bar. A SAE four-bolt flange is provided for the ports to simplify mounting into rigid manifold blocks.
For power-train sizing, the pump withstands 820 Nm of input shaft torque while sustaining a continuous outlet pressure of 172 bar, a combination suited to medium-pressure industrial and mobile systems. The rectangular housing measures 16.74 in in length, 8.38 in in width, and 7.34 in in height so it fits between common motor brackets and reservoir walls. Shipping mass is 101 lb, permitting a single technician to lift it with standard shop hoists. These physical parameters minimize frame stress and simplify alignment during maintenance. The dual-section layout lets one prime mover feed two circuits, which lowers installation cost and reduces coupling count.
