The V20NF 1D6T 238C6G 22 pump belongs to the Square Vane Pumps series from Vickers and is intended for hydraulic automation tasks that require compact flow generation. It displaces 19.5 cm³ per revolution (1.19 in³ per revolution), so each shaft rotation delivers a predictable volume of oil to the circuit. The unit withstands a maximum working pressure of 172 bar (2500 psi) to support medium-pressure systems, and it can rotate up to 3400 rpm when rapid response is needed. A ring capacity of 6 GPM balances flow against efficiency for steady service. The flow control valve cover with an internal drain maintains outlet stability while returning case leakage directly to the suction side. A 2-bolt SAE A flange simplifies mounting to standard power take-offs, and an 11-tooth 16/32 DP spline transfers torque from the prime mover without backlash. The shaft projects 1.25 in beyond the housing, providing adequate engagement length for couplings.
Inlet and outlet connections are arranged for straightforward plumbing: a 1.312-12UN-12B straight-thread port receives the supply line, the primary discharge exits through a .750-16 threaded port, and auxiliary flow can be routed from a .875-14 threaded secondary outlet, while reservoir return is handled by a .750-16 threaded tank port. The inlet sees a positive pressure limit of 0.7 bar (10 psi) to avoid seal washout, and it may tolerate up to 5 in Hg of vacuum for flooded-suction service. A shaft major diameter of 0.748 in matches common couplings, and a single lip seal with a sealed bearing restricts external leakage and keeps contaminants away from the rolling elements during continuous duty.
