The 2520V17A12 1AA22R pump belongs to the V Series Vane Pumps manufactured by Vickers and is applied in hydraulic automation to supply steady oil flow to valves and cylinders. The shaft-end displacement is 55 cm³ per revolution, so each rotation moves that volume into the system, while a rated flow of 17 gpm at 1200 rpm supports medium-power circuits without oversizing the prime mover. Clockwise shaft rotation matches most electric motor outputs used on industrial skids. A keyed shaft with a 3/16 in square key transmits torque reliably and aligns the drive hub. Flange mount installation holds the housing rigidly to the prime mover face, reducing misalignment. The inlet side must not exceed 1.4 bar (20 psi) to prevent cavitation and seal stress during flooded-suction operation.
The cover end of the same unit delivers 40 cm³ per revolution, providing an auxiliary stream that can run pilot functions or separate actuators; at 1200 rpm this section outputs 12 gpm. Outlet ports can be arranged opposite the inlet in orientation O1 or set 135° counter-clockwise in orientation O2, giving designers two piping options within cramped enclosures. Fluid leaves through an SAE 4-bolt flange, and inch-threaded ports let standard North American adapters screw directly into place; these details shorten service time because hoses can be removed without moving the pump. A standard seal keeps oil inside the housing during continuous duty. Combined, these attributes make the pump suitable for machines that need dual flow sources and straightforward maintenance.
