The 35V25A 1C22R is produced by Vickers within the V Series Vane Pumps series and serves as a source of controlled hydraulic flow for automated machinery. It displaces 81 cm³ per revolution (4.94 in³ per revolution), giving predictable volume with each shaft turn. At 1200 rpm and 100 psi it delivers a rated capacity of 25 gpm, which helps size downstream actuators and coolers. The model endures a continuous system pressure of 172 bar (2500 psi) so it fits medium-pressure circuits. Operating speed can reach 1800 rpm when high flow is needed, while a minimum of 600 rpm supports slower duty cycles without stalling. Viewed from the shaft end, rotation is clockwise, matching common right-hand prime movers used in industrial power units.
The inlet side tolerates up to 1.4 bar (20 psi) but can operate with suction down to −0.17 bar (5 inHg), allowing flexible reservoir placement above or below the pump centerline. Flange mounting secures the housing to standard engine or motor adapters without additional brackets. The outlet is inline with the inlet in the C orientation, simplifying rigid pipe runs. Pressure lines attach through an SAE 4-bolt flange, and all port threads follow inch standards to align with North American fittings. Connections are therefore fast to assemble and seal, while the specified arrangement maintains compact layouts inside hydraulic manifolds and mobile equipment frames.
