The V10 1S6S 11D20 vane pump belongs to the Square Vane Pumps series and is produced by Vickers. It provides hydraulic power for automated circuits by converting mechanical rotation into pressurized flow. Its displacement is 19.5 cm3 per revolution, which sets the volume of oil delivered each shaft turn and aids flow calculation. Ring capacity of 6 US gpm supports moderate flow applications such as machine tool lubrication loops. A maximum operating pressure of 152 bar allows the pump to sustain system loads without overstress, while a top speed of 3000 r/min defines the shaft rpm limit for continuous service. Rotation is right-hand when viewed from the shaft end, so drive arrangements must match clockwise motion. The pressure angle of 30° balances vane loading against efficiency, and an inlet vacuum limit of 5 in Hg guards against cavitation by restricting suction side pressure drop.
This pump mounts to power units through a 2-bolt SAE A flange, simplifying interchange with standard industrial motor adapters. The inlet port uses a 1-5/16-12 thread that matches common hydraulic hose fittings and maintains adequate suction diameter. Discharge is routed through a 3/4-16 straight thread outlet, providing a sealed connection for return lines, and the outlet is positioned 90° clockwise from the inlet to ease hose routing within compact manifolds. Shaft design includes a major diameter of 0.623 in for torque transmission and a minor diameter no smaller than 0.465 in to preserve spline root strength. The nine-tooth spline with a 16/32 DP pitch enables positive drive coupling while minimizing backlash. These mechanical features complete the unit’s specifications and ensure compatibility with typical industrial hydraulic motors and gearboxes.
