The 2520V21A12 1AA22R pump belongs to the V Series Vane Pumps from Vickers and supplies hydraulic power to automated machinery. The first pumping section displaces 67 cm³ per revolution, which supports a rated flow of 21 gpm when driven at common motor speeds. Clockwise rotation viewed from the shaft end aligns with standard drive arrangements and maintains correct internal lubrication paths. A flange mount fixes the housing securely to the power unit, keeping shaft and coupling concentric. Both inlet and outlet ports use a 4-bolt flange with inch threads so rigid piping can be attached without adapters. A standard seal contains the working fluid and prevents external leakage under normal service conditions.
The second section provides 40 cm³ per revolution and delivers 12 gpm, giving the circuit a lower-flow branch for auxiliary actuators. Outlet 1 withstands 172 bar, enabling high-pressure work functions, while Outlet 2 is limited to 159 bar for moderate-duty tasks. A speed window from 600 to 1800 rpm lets the pump run with a variety of electric or combustion prime movers without exceeding cartridge limits. Outlet 1 sits opposite the inlet, and Outlet 2 is set 135° counter-clockwise from the inlet, which simplifies hose routing in tight power packs. These parameters combine to offer dual-flow, dual-pressure capability within a single compact housing for hydraulic automation.
