The 4535V42A38 1AA22R pump is produced by Vickers within the V Series Vane Pumps series and is intended to supply steady flow to hydraulic actuators in automated machinery. It installs through a flange mount, which aligns the housing accurately to motor adapters and resists side loads from connected piping. The unit turns clockwise when viewed from the shaft end, so drive couplings must match this direction of rotation. At the cover end its displacement is 121 cm³ per revolution, delivering a nominal 38 gallons per minute to circuits that require medium volume flow. Continuous working pressure is limited to 172 bar, allowing the pump to operate in systems that use standard industrial hose ratings. Speed can be reduced to 600 rpm for low-noise operation or increased to 1800 rpm for peak production rates without exceeding design limits. The assembled pump weighs 53.5 kg, so lifting equipment should be arranged for safe installation.


This double pump supplies additional flow through the shaft end where displacement rises to 138 cm³ per revolution, providing a rated capacity of 42 gallons per minute for parallel hydraulic functions. Fluid enters through an FL1-32 inlet flange that uses a 0.625-11 UNC thread, ensuring positive sealing under suction conditions. Outlet lines are connected with SAE four-bolt flanges; the primary outlet employs an FL1-12 flange with 0.50-13 UNC bolts, while the secondary outlet uses an FL1-10 flange with 0.437-14 UNC hardware, permitting balanced mounting of dual return hoses. Both outlets are positioned opposite the inlet in the AA orientation, which simplifies manifold design by keeping pressure ports on the same side of the pump body. These porting features streamline plumbing and help reduce assembly time on automated hydraulic skids.
