The V10 1S6S 11C20R vane pump is manufactured by Vickers as part of the Square Vane Pumps series, and it supplies hydraulic power to automated machinery by converting mechanical rotation into controlled fluid flow. It carries design number 20, which defines the internal cartridge revision used by this model. Each revolution displaces 19.5 cm³ (1.19 in³) of oil, so at the reference point of 1200 rpm and 100 psi the pump delivers 6 US gpm to downstream actuators. The unit withstands continuous pressures up to 152 bar (2200 psi), enabling use in medium-pressure circuits such as clamping or indexing systems. A maximum operating speed of 3000 rpm prevents excessive wear while allowing variable-speed drives to match cycle requirements. Right-hand rotation matches common engine and electric-motor outputs, and a 30° pressure angle balances vane loading to maintain volumetric efficiency.
Installation details support quick replacement in field service. The pump uses a two-bolt flange for mounting, which centers the housing and resists torsional loads from the drive. Fluid enters through a 1-5/16-12 UN-2B inlet thread and exits through a .750-16 UNF-2B outlet thread that sits in line with the inlet port, simplifying rigid pipe runs. The inlet can accept positive pressures up to 0.7 bar (10 psi) or sustain a vacuum of 5 in Hg during cold-start conditions without cavitation. A shaft with nine spline teeth engages the prime mover, and the spline follows a 16/32 DP flat-root profile for accurate torque transmission. These mechanical features, together with the inline port orientation, fit confined manifolds used in automated tooling.
