The 4535V42A30 11AA22R pump is manufactured by Vickers for the V Series Vane Pumps series and supplies pressurized oil to hydraulic automation circuits. At the shaft end, displacement is 138 cm³ per revolution (8.4 in³ per revolution), producing a rated flow of 42 gpm when the drive speed is 1200 rpm, which supports large-volume actuators. The unit turns clockwise when viewed from the shaft end, so it aligns with conventional right-hand prime movers. Stable operation is possible down to 600 rpm, enabling energy-saving slow cycles without cavitation. Continuous working pressure reaches 172 bar (2500 psi), giving the pump capacity for medium-pressure workholding or mobile machinery lines. The inlet circuit handles positive pressures up to 1.4 bar (20 psi) and can tolerate suction down to –0.17 bar (5 inHg), allowing flexible reservoir placement above or below the mounting plane. Power is transmitted through a 14-tooth 12/24 MDF spline, which mates with standard SAE shafts used on electric motors and diesel engines.
The cover end of the same pump delivers 97 cm³ per revolution (5.9 in³ per revolution), yielding 30 gpm at 1200 rpm for auxiliary actuators that need a separate flow source. A flange mount arrangement fixes the housing directly to the prime mover, shortening the driveline and easing alignment. Fluid enters through an SAE 4-bolt flange that is secured by a .625-11 UNC-2B inlet tap, while discharge leaves through a .50-13 UNC-2B tapped flange; both outlet ports sit opposite the inlet to simplify hose routing in compact power units. These opposing outlets are helpful where return and pressure lines must be spaced evenly around the pump body.
