The 3525V30A17 1AA22R hydraulic pump belongs to the V Series Vane Pumps and is produced by Vickers for closed-loop automation circuits. This double configuration carries design number 22, a revision that aligns internal clearances with current efficiency targets. Its vane design produces low ripple flow, which minimizes vibration in sensitive actuators. The shaft-end section displaces 97 cm³ per revolution (5.9 in³/rev) to drive primary motion functions, while the cover-end section provides 55 cm³ per revolution (3.4 in³/rev) for auxiliary branches. When driven at 1200 rpm and 6.9 bar, the unit operates at its rated test conditions so installers can verify performance against a common baseline. Clockwise rotation at the shaft end matches standard electric motor layouts, simplifying coupling alignment in modular power units.
At those test conditions, Outlet 1 delivers 30 gpm to feed high-demand cylinders, while Outlet 2 supplies 17 gpm for secondary loops. Outlet 1 is positioned opposite the inlet to shorten manifold paths on straight-through blocks, and Outlet 2 sits 135° counter-clockwise from the inlet so designers can separate return and pressure lines within compact housings. The flange mount provides rigid support on power-unit plates and maintains shaft alignment under load. A SAE four-bolt flange port connection speeds service by matching standard hose kits, and the inch thread form allows direct use of North American fittings without adapters. Standard seals are included to balance cost with compatibility for common hydraulic oils, completing the pump’s feature set for general industrial automation.
