The V20 1P9P 15A11 vane pump is built by Vickers as part of the Square Vane Pumps series and supplies consistent flow in hydraulic automation circuits. With a displacement of 29.7 cm³ per revolution (1.81 in³/rev), it meters the volume pushed each shaft turn for predictable actuator speed control. At 1200 rpm and 100 psi the pump delivers 75.0 L/min, providing a baseline value for sizing tanks and coolers. A maximum operating pressure of 172 bar (2500 psi) lets the unit drive cylinders and motors that demand high force without overstressing components. To reach full output at its 2800 rpm speed limit, the drive motor must supply 26.5 kW (35.5 hp), so power transmission parts can be specified correctly. The shaft spins to the right, ensuring proper inlet and outlet orientation in right-hand drive systems. Internal geometry identified by ring size 9 defines the vane track diameter and supports the stated flow and pressure range.
Installation details align the V20 1P9P 15A11 with common industrial layouts. A SAE J744 101-2 two-bolt front flange mount secures the housing to standard pump pads for quick replacement. The inlet port is a 1-1/4 NPTF thread that accepts rigid suction piping sized to minimize pressure drop, while the outlet port uses a 3/4 NPT thread for compact high-pressure lines. Because the outlet is positioned opposite the inlet, hoses can run parallel to the pump body and reduce crossover in tight manifolds. A Buna-N seal set protects against leaks when the pump handles petroleum-based fluids common in factory automation. Physical dimensions of 8.12 in in length and 4.79 in in height permit placement inside narrow power units, and the 18 lb mass allows one-person handling during service.
