The 3525V30A17 1AA22L pump belongs to the V Series Vane Pumps from Vickers and supplies hydraulic power for automated machinery. It withstands a maximum pressure of 172 bar (2500 psi) so it can maintain stable flow in medium-pressure circuits, and it operates at up to 1800 rpm to suit common electric motor speeds. Counterclockwise rotation at the shaft end matches drives that turn in that direction, preventing the need for additional gearing. A flange-mount arrangement keeps the housing rigidly aligned with the prime mover, reducing vibration. The inlet uses a 4-bolt flange connection that shortens service time when hoses are replaced, and the 5/8-11 UNC-2B x 30.0 mm bolt tap in the flange provides secure thread engagement under pulsating load. Inch-based port threads ensure direct compatibility with standard North American hydraulic fittings, eliminating adapter requirements.
The pump weighs 34.5 kg (76 lb), a mass that supports manual positioning with basic lifting aids while reflecting a robust cast-iron build. A cover-end displacement of 55 cm³ per revolution feeds auxiliary functions, whereas a shaft-end displacement of 97 cm³ per revolution delivers higher volume to primary actuators. Flow capacity mirrors these values, with 17 gpm available from the cover end and 30 gpm from the shaft end so designers can size downstream components accurately. Port orientation supports clean plumbing: the first outlet sits opposite the inlet for straight routing, and the second outlet is 135 degrees counterclockwise from the inlet to separate return lines and minimize hose crowding. Both outlets use a 4-bolt flange style that distributes clamping load evenly across the gasket, maintaining a reliable seal during cyclical pressure changes.
