The V10 1S5S 11D20L hydraulic pump belongs to the Square Vane Pumps series manufactured by Vickers. It supplies controlled flow to automated hydraulic systems, relying on vane elements to minimize pressure ripple. A geometric displacement of 1.00 in³ per revolution, equivalent to 16.4 cm³ per revolution, allows the circuit designer to predict flow accurately at any driven speed. The internal ring supports 5 gallons per minute so the pump pairs well with compact cylinders and small conveyor drives. Continuous service is rated to 172 bar (2500 psi), giving adequate margin for mobile and industrial machines that run at medium pressure. A speed limit of 3200 rpm lets the unit mount directly to common electric motor brackets without a speed reducer. Counter-clockwise rotation when viewed from the shaft end matches left-hand drive trains, and the 1-5/16-12 straight-thread inlet provides a robust seal against suction-side leaks. Installation uses a two-bolt SAE-A flange, permitting quick removal during maintenance.
Fluid leaves the housing through a 3/4-16 straight-thread outlet positioned 90° clockwise from the inlet so hoses can exit at right angles and clear nearby components. A shaft extension of 2.66 in offers enough length for flexible couplings while still keeping the assembly compact. Torque is transmitted by a nine-tooth spline; its 16/32 DP pitch balances root strength with smooth engagement, the major diameter measures 0.623 in, and the minor diameter remains at least 0.465 in to preserve contact under load. The vane pumping arrangement introduced earlier maintains volumetric efficiency at the stated flow figure while limiting acoustic noise, which benefits automated lines with proximity sensors. Together these connection dimensions and drive features allow the pump to integrate into standardized SAE mountings and deliver the specified pressure and flow without additional adapters.
