The 2520V17A5-1XX22X vane pump belongs to the V Series Vane Pumps manufactured by Vickers and supplies fixed-displacement flow for hydraulic automation. Installation is simplified by a flange mount, and both the inlet and the two discharge ports share the SAE four-bolt flange pattern while inch thread connections accept standard fittings. The pump weighs 20.5 kg (45 lb), permitting direct motor coupling without additional supports. Rotational inertia is limited to 0.001309 N·m·s², allowing quick acceleration when the drive starts. Continuous operation is permitted up to 1800 rpm, provided the inlet pressure does not exceed 1.4 bar (20 psi) and the hydraulic fluid viscosity remains between 13 and 54 cSt to prevent cavitation and vane wear.
The first outlet displaces 55 cm³ per revolution and yields 17 gpm for primary actuators, whereas the second outlet delivers 18 cm³ per revolution and 5 gpm for auxiliary circuits. Outlet 1 withstands pressures up to 172 bar (2500 psi) while outlet 2 is rated for 207 bar (3000 psi), enabling separate circuits to run at different load levels from the same unit. Observing these pressure limits protects the vanes and seals already conditioned by the viscosity range noted earlier. The dual-flow arrangement allows designers to allocate high pressure to a compact cylinder and lower flow to a secondary function without adding extra pumps, and because all ports share the SAE flange interface mentioned previously, piping changes between circuits remain straightforward.
