The 4525V50A14 86CC22R vane pump belongs to the V Series Vane Pumps and is manufactured by Vickers for hydraulic automation in machines that need two independent flows from a single drive. It delivers 162 cm³ per revolution on the shaft end, enabling high flow to primary circuits, while a shaft-end rating of 50 gpm at 1200 rpm and 100 psi keeps large actuators supplied without cavitation. The cover end provides a secondary displacement of 45 cm³ per revolution so auxiliary functions can share the same pump, and it supplies 14 gpm at the same reference speed and pressure for stable low-demand branches. A maximum speed limit of 1800 rpm matches standard electric motor outputs, and continuous pressure capability reaches 172 bar (2500 psi) to serve medium-pressure systems. Right-hand clockwise rotation aligns with common engine pads, and an SAE four-bolt flange port connection allows quick fitment to standardized manifolds.
The pump accepts inlet pressure up to 1.4 bar (20 psi), letting it work with pressurized reservoirs, and it tolerates vacuum down to −0.17 bar (5 in Hg) so tank-top mounting above the oil level remains possible. The suction port is tapped .625-11 UNC-2B, giving a secure thread for the inlet flange, whereas discharge port #1 uses a .50-13 UNC-2B thread and discharge port #2 uses a .375-16 UNC-2B thread to accommodate different line sizes. A standard SAE pilot specified by ISO 3019-1 centers the housing in the drive pad for precise alignment during installation. Port orientation code CC sets the flange positions to suit compact plumbing on right-hand rotation layouts, ensuring hose runs stay short and unobstructed.
