The V20F 1P6P 38B5G 22 vane pump is produced by Vickers and belongs to the Vane Pumps series, where it provides positive-displacement flow for hydraulic automation loops. Right-hand rotation matches common engine and motor drive directions, and a SAE rated capacity of 6 US gpm at 1200 rpm and 100 psi defines its baseline delivery. A 1.25 in NPT inlet port connects to standard suction hose, while the pressure port uses a 0.750-16 UNF O-ring boss to maintain a sealed high-pressure joint. The unit includes a 0.50 in NPT tank port so excess fluid can return to reservoir without restriction. With the outlet positioned 90 ° counterclockwise from the inlet, routing of pressure and return lines is simplified in compact manifolds. A built-in relief valve is preset to 121 bar (1750 psi) to protect downstream components from overload.
The flow control and relief cover regulates discharge volume and opens when system pressure exceeds the internal setting to stabilize circuit flow. A No. 5 orifice measuring 0.147 in in that cover meters bypass fluid for precise trimming of actuator speed. Sealed bearings keep grease contained and exclude contaminants, extending service life in dirty environments. A single-lip shaft seal blocks oil from escaping along the drive shaft and prevents air ingress during suction strokes. The 11-tooth 16/32 DP 30 ° shaft spline mates with standard hydraulic couplings, and the 0.590 in minor diameter ensures correct hub engagement. A 2-bolt SAE A flange enables quick, rigid mounting to power units or gearboxes, completing the mechanical interface of this pump.
