V20 1P6P 1C 11

The V20 1P6P 1C 11 vane pump is part of the Square Vane Pumps series from Vickers and is intended to move hydraulic fluid at a fixed displacement in automated machinery. A sealed bearing keeps contaminants out of the rotating group so service life is extended without frequent relubrication. Its displacement of 19.5 cm³ per revolution defines the volume delivered each turn and supports steady flow in compact power units. The maximum speed limit of 3400 rpm allows the pump to be coupled to high-speed electric motors while maintaining dimensional stability. Input power at that peak speed reaches 21.6 kW, indicating the mechanical energy that must be supplied to achieve full capacity. A maximum operating pressure of 172 bar permits the pump to work in medium-pressure circuits without overstressing internal plates, and right-hand (clockwise) shaft rotation matches drives that follow standard SAE direction conventions.

The unit mounts with a 2-bolt SAE-A flange, enabling quick alignment on common hydraulic manifolds and reducing installation time. A 1.25 in NPT threaded inlet port accepts widely available suction hoses so supply plumbing remains simple, while the 0.75 in NPT outlet port provides a secure connection to pressure lines of corresponding size. The outlet is positioned in line with the inlet, which streamlines tube routing in narrow power packs. Rated capacity is 6 US gpm when the shaft turns 1200 rpm at 100 psi, giving designers a reference point for sizing reservoirs and coolers. A single-lip shaft seal prevents external leakage under normal operating pressure and protects the drive end from oil splash, ensuring clean operation around electric motors and couplings.
