V20F 1D6S 38D4H 22L

The V20F 1D6S 38D4H 22L is produced by Vickers as part of the Square Vane Pumps series and delivers hydraulic flow for automated machinery. A vane pumping mechanism moves fluid with low pulsation, supporting stable actuator motion. The ring capacity of 6 GPM establishes its expected delivery rate for moderate-demand circuits. Sealed bearings keep contaminants out of the rotating group to lengthen operating life and cut service intervals. Fluid enters through an inlet port threaded 1.312-12 UN-12B, allowing direct connection to common SAE adapters, and exits through a pressure port threaded 0.750-16 UN-2B to match standard high-pressure lines. Installation is handled by an SAE-A 2-bolt flange, so the unit fits pumps of similar frame size without extra brackets.

The cover includes a flow control valve, giving users an integrated method to regulate downstream volume without adding external valves. A single lip shaft seal prevents oil from leaving the housing while minimizing drag on the drive shaft. Power is transmitted through an 11-tooth 16/32 DP flat root side fit spline that mates with industry-standard couplings for reliable torque delivery. Return fluid moves to reservoir through a tank port threaded 1.0625-12 UN-2B, ensuring leak-free attachment of return hoses. Together these design choices support compact installation, controlled flow, and long service life in hydraulic automation systems.
