The 3520VQ30A14 11AA20 vane pump belongs to the VQ Thru-Drive Vane Pumps series from Vickers and serves to deliver pressurized fluid in automated hydraulic circuits. The front pumping section displaces 97.7 cm³ per revolution, while the rear section provides 45.9 cm³ per revolution so two separate circuits can be driven from one shaft. Combined flow reaches 215.1086976 l/min, enabling steady actuator speed in continuous duty service. The unit tolerates working pressures up to 210 bar, and its right-hand shaft rotation aligns with standard clockwise prime movers. A cast-iron housing resists mechanical and thermal stress during prolonged operation.
The inlet uses a 1 1/2-inch 4-bolt flange, the front outlet sits inline with the inlet on a 4-bolt SAE J518C flange, and the rear outlet is positioned 135° counterclockwise from the inlet to simplify hose routing. Buna-N seals prevent leakage when the pump handles petroleum-based oils. Overall dimensions are 13.2 in in length, 8.38 in in width, and 6.41 in in height, while the assembled weight of 75 lb allows handling with light lifting aids.
