The 3520V38E5 11BB22R vane pump belongs to the V Series Vane Pumps from Vickers and supplies pressurized fluid to hydraulic automation systems. It turns clockwise, which mates with right-hand industrial prime movers and maintains inlet sealing on the timing side. A shaft end displacement of 121 cm³ per revolution (7.4 in³/rev) establishes the volume of oil delivered during each rotation, so circuit designers can calculate flow at any speed. At 1200 rpm this end produces a rated flow of 38 gpm, providing the main supply for cylinders or motors that require moderate to high volume. The shaft end is limited to 172 bar (2500 psi) of pressure, protecting the pump cartridge and downstream components from overload. An operating range beginning at 600 rpm prevents insufficient internal lubrication at low speed, while the 1800 rpm ceiling keeps vane tip velocity within acceptable limits for temperature and wear control.
The cover section handles auxiliary functions within the same housing. Its displacement is 18 cm³ per revolution (1.1 in³/rev), creating a smaller delivery for pilot or servo branches. That passage yields 5 gpm at 1200 rpm, giving stable control flow without adding a separate pump. The cover end tolerates up to 207 bar (3000 psi), allowing it to share higher pressure circuits when needed. A flange mount keeps the pump rigid on power unit manifolds and reduces alignment errors with the drive shaft. Fluid enters through a 4-bolt flange inlet so the suction line can be secured against vibration. Discharge options include a 4-bolt flange outlet located 90° counter-clockwise from the inlet for straightforward right-angle plumbing, and a straight-thread SAE outlet located 45° counter-clockwise for compact hose routing in tight panels. These port orientations give builders flexibility when arranging return valves and filters around the housing.
