The 4525V60E17 1AA22R pump is manufactured by Vickers for the V Series Vane Pumps series. It supplies hydraulic power for automated machinery where steady flow and moderate pressure are required. A 12-vane cartridge produces uniform delivery while limiting pulsation. The shaft end section displaces 193 cm³ per revolution, which yields 60 USgpm at 1200 rpm for primary circuits. When anti-wear oil is used the unit can turn at speeds up to 1800 rpm, allowing higher output without cavitation. Clockwise rotation matches standard engine couplings, and a moment of inertia of 0.003732 N·m·s² reduces starting torque demands on the drive motor. The housing weighs 46.0 kg (101 lb), so the mounting base must be rigid enough to support the mass during operation.
At the opposite cover end the pump displaces 55 cm³ per revolution and delivers 17 USgpm at 1200 rpm, providing a secondary flow path for auxiliary actuators. Continuous operation is permitted down to 600 rpm, which maintains lubrication during slow machine cycles. The inlet can tolerate negative pressure to –0.17 bar (5 in Hg) for tank-top installation, while a ceiling of 1.4 bar (20 psi) prevents seal overload when flooded. System pressure may be pushed as high as 172 bar (2500 psi), enabling the unit to drive cylinders or motors that require substantial force. These limits define the safe operating envelope and help designers size filtration, piping, and drive components for dependable hydraulic automation.
