The V10 1S2S 11A20 vane pump belongs to the Square Vane Pumps series produced by Vickers. Designed for hydraulic automation, it moves oil from the reservoir to actuators and manifolds while maintaining stable flow under varying load. A displacement of 6.6 cm³ per revolution sets the volumetric output generated by each shaft turn, letting designers predict flow at any given speed. Operation up to 4500 r/min supports fast-running prime movers found in mobile equipment. At that top speed and the rated 172 bar pressure, the pump delivers 27.7 L/min, supplying medium-size cylinders or motors without oversizing the drive. Driving requirements peak at 10.1 kW under the same conditions, so electric motors or engines can be matched accurately. An internal ring capacity of 2 GPM governs the amount of case-drain oil that circulates for vane shuttling and heat removal, preventing excess temperature rise during continuous duty.
Mounting uses a 2-bolt SAE-A flange, enabling direct attachment to standard power take-off pads on gearboxes or engine housings and reducing adapter hardware. The inlet port carries a 1 5/16-12 thread to accept common suction fittings, while the outlet port employs a 3/4-16 straight thread to connect to pressure lines fitted with O-ring bosses. Overall dimensions of 5.800 in length, 5.120 in width, and 4.350 in height permit placement inside compact pump stacks or crowded machine frames. The shaft extends 2.66 in beyond the mounting face so couplings can clear nearby castings, and its 0.623 in major diameter withstands the torsion imposed by the 10.1 kW drive. Nine spline teeth transfer torque with minimal backlash, and clockwise rotation viewed from the shaft end matches the direction of most engine PTOs, avoiding cross-drive idlers. Together these interface details simplify installation, alignment, and service in hydraulic power units.
