4525V60A171BA22R

The 4525V60A171BA22R vane pump belongs to the Vane Pumps series and is produced by Vickers for hydraulic automation circuits. It moves fluid from a reservoir to actuators, driven by a shaft-end displacement of 193.4 cm³ per revolution, which provides high volume transfer at moderate speeds. A rated shaft-end flow of 60 US gpm at 1200 rpm and 100 psi supports circuits that demand steady output for multiple functions. SAE four-bolt flanges on the inlet and outlet ports simplify attachment to standard manifold blocks and lower the risk of leakage. Outlet 1 is located 90° counter-clockwise from the inlet so plumbing can be routed cleanly in tight power units. The design also accepts a positive inlet pressure up to 1.4 bar (20 psi), permitting use with boost-fed suction lines without harming shaft seals.

The cover-end section features a displacement of 55.2 cm³ per revolution, giving a secondary flow source sized for pilot or low-demand branches. It delivers a cover-end flow of 17 US gpm at 1200 rpm and 100 psi, maintaining control pressure when the main circuit is idle. The pump tolerates a maximum inlet vacuum of 5 in Hg, enabling operation with reservoirs positioned below the pump centerline without cavitation. Outlet 2 exits 135° counter-clockwise from the inlet, providing another port orientation to separate return and pressure lines within the same housing. These combined characteristics allow the unit to supply dual flows in one compact envelope for automated machinery.
