The V20F 1P0P 38D6H 22L pump belongs to the Square Vane Pumps series and is manufactured by Vickers. It is intended to supply controlled hydraulic flow for automated machinery. The unit turns in a left-hand counterclockwise direction, matching installations that require CCW drive shafts. A 1.25 in NPT inlet port permits direct connection to standard suction lines. The internal circuit includes a No. 6 flow-control orifice that meters 23 L/min to stabilize delivery. Continuous service is supported up to 172 bar (2500 psi), fitting medium-pressure circuits. Shaft speed may reach 2800 rpm without exceeding rated limits, allowing compact power packs to achieve required flow rates.
Discharge plumbing is simplified because the outlet is positioned 90° clockwise from the inlet, identified as code D. The outlet port uses a .750-16 UNF-2B SAE O-ring thread for a sealed pressure connection. Inside the cartridge, the vanes operate on a 30° pressure angle to balance radial loads. A built-in relief valve opens at 140 bar (2000 psi) to protect downstream components. The drive shaft carries an 11-tooth involute spline with a 0.590 in minor diameter and a 16/32 DP pitch, providing torsional rigidity with common couplings. Return oil exits through a 0.50 in NPT tank port, completing the hydraulic circuit.
