The 2520V17A12-1XX22X pump is part of the V Series Vane Pumps and is manufactured by Vickers for hydraulic automation tasks that require stable oil delivery. The cover end displacement is 40 cm³ per revolution (2.5 in³/rev), giving a secondary section that moves a moderate volume each turn, while its cover end rated flow of 12 gpm maintains a steady supply to auxiliary actuators at nominal speed. On the primary side, the shaft end displacement reaches 55 cm³ per revolution (3.4 in³/rev) so the main circuit receives more volume, and the shaft end rated flow of 17 gpm supports higher demand functions without flow starvation. A maximum speed of 1800 rpm limits the drive motor selection and keeps internal vanes within their mechanical stress range. The pump mounts by a flange to align accurately with the power unit, and its ports accept SAE 4-bolt flanges for leak-free high-pressure joints; inch threads in those ports simplify connection to common North American fittings.
For circuit loading, outlet 1 tolerates up to 172 bar (2500 psi) so it can power cylinders or motors that require full system pressure, while outlet 2 is rated for 159 bar (2300 psi) to handle slightly lighter duties. The inlet side must not exceed 1.4 bar (20 psi) to protect shaft seals, yet it may go as low as –0.17 bar (5 inHg) to accommodate suction lift without cavitation when tanks are below the pump. Fluid temperature should remain at or below 65 °C (150 °F) to preserve oil life and vane clearances. Operation is recommended with viscosities no lower than 13 cSt so lubrication films stay intact and no higher than 54 cSt so flow losses through the galleries stay within acceptable limits, completing the viscosity window needed for reliable service.
