The 3525V25A21 86AA22R vane pump is produced by Vickers within the V Series Vane Pumps series. It supplies hydraulic power in automated systems, converting shaft input into controlled fluid flow for actuators and valves. The unit tolerates a maximum input shaft torque of 600 Nm (5300 lbf-in), allowing it to drive high load circuits without mechanical overload. It reaches up to 1800 rpm on anti-wear oil while remaining stable down to a minimum speed of 600 rpm, so it can match variable drive arrangements. Clockwise rotation from the shaft end defines motor pairing and hose routing. A flange mount simplifies alignment to pump drives and keeps housing stresses low. The 5/16 in square shaft key transfers torque to the rotor with positive engagement. SAE 4-bolt flange ports provide rigid pipe connection, and inch threads on auxiliary fittings maintain compatibility with common North American hose assemblies.
The pump sustains 172 bar (2500 psi) when operated with anti-wear oil, 159 bar (2300 psi) on water-glycol blends, and 69 bar (1000 psi) with phosphate-ester fluids, so circuit designers can select media based on fire resistance or lubricity while respecting these limits. Outlet 1 delivers 81 cm³ per revolution and supplies 25 gpm at 1200 rpm, serving primary actuators that need higher flow. Outlet 2 offers 67 cm³ per revolution and provides 21 gpm at the same speed, enabling a secondary circuit without an additional pump stage. The AA orientation sets the No. 2 port at 135° counter-clockwise from the reference, aiding manifold layout in confined power units. These pressure capacities, displacement figures, and port geometry support reliable hydraulic automation where dual flows and moderate operating pressures are required.
