The 35V38A 1C22R vane pump is produced by Vickers in the V Series Vane Pumps series for hydraulic automation circuits. It carries design number 22, which distinguishes its internal geometry within the series. The unit displaces 121 cm³ per revolution, enabling a rated flow of 38 gpm at 1200 rpm and 100 psi to supply medium-size actuators. A clockwise shaft-end rotation matches common right-hand drive layouts, and a 31.75 mm shaft diameter provides the torsional strength required for industrial couplings. Operating speed ranges from a minimum of 600 rpm to a maximum of 1800 rpm, allowing integration on variable-speed prime movers without flow pulsation.
The pump sustains continuous outlet pressure up to 172 bar, while the inlet side tolerates 1.4 bar to prevent cavitation in flooded suction arrangements. Moment of inertia is 0.001395 N·m·s², so drivetrain acceleration loads remain low during start-up sequences. Flange mounting simplifies alignment to electric motors, and SAE four-bolt port flanges offer leak-free connections to standard pipe manifolds. During operation at 1800 rpm the acoustic emission reaches 69 dB(A), supporting installations where noise controls are applied. A mass of 22.7 kg allows single-person handling and straightforward maintenance swaps.
