The 4535V50AM2511DA22R vane pump is built by Vickers for the V Series Vane Pumps series and serves as a fixed-displacement source of hydraulic flow in automated presses and machine tools. Its shaft end section delivers 162 cm³ per revolution, allowing 50 US gpm at 1200 rpm to reach downstream actuators, while the cover end section moves 81 cm³ per revolution to supply an additional 25 US gpm at the same speed. A maximum continuous pressure rating of 172 bar (2500 psi) lets the unit maintain force in circuits that require high working loads without overstressing internal components. The pump withstands rotational inputs up to 1800 rpm for peak cycling rates and remains stable down to 600 rpm so low-speed operations can be performed without loss of lubrication. A right-hand clockwise rotation matches common electric motor drives, and the 127 mm (5.00 in) pilot diameter centers the housing on standard SAE mounting faces to simplify alignment during installation.
The casing weighs 53.5 kg (118 lb), so a rigid bracket or baseplate is needed to support the mass in overhead or mobile frames. A rotor moment of inertia of 0.04031 lb-in-s² limits start-up torque, allowing smaller motors to bring the pump to speed quickly. Fluid enters through an M16 x 30.0 mm tapped inlet port, and the design accepts up to 1.4 bar (20 psi) inlet pressure or draws fluid under a vacuum down to 0.17 bar (5 in Hg), giving flexibility for flooded or tank-top mounting. Discharge lines connect to two separate ports; the primary outlet uses an M12 x 23.8 mm tap, while a secondary outlet is threaded M10 x 20.1 mm, which helps users route independent flows to different circuits without adapters. These port sizes, together with the operating limits stated earlier, define the envelope for the pump and ensure repeatable flow delivery in industrial hydraulic automation.
