V20F 6S6T 15C8K 22 121

The V20F 6S6T 15C8K 22 121 is manufactured by Vickers within the Square Vane Pumps series and is intended to supply consistent hydraulic flow to automated machinery. The displacement of 19.5 cm³ per revolution, equivalent to 1.19 in³ per revolution, sets the volume moved each shaft rotation for predictable circuit sizing. A rated delivery of 6 USgpm at 1200 rpm and 100 psi provides a baseline output for low-speed drive arrangements. The shaft can be driven up to 3400 rpm so the unit can support higher flow demands when motor capacity allows. A two-bolt SAE B flange mount simplifies direct attachment to standard power take-off pads. Fluid enters through a 1.25 NPT inlet port, exits through a .750-16 UNF-2B outlet port, and returns to the reservoir through a .50 NPT tank port; these threaded connections match common hose fittings and reduce plumbing time.

For pressure regulation, the V20F 6S6T 15C8K 22 121 accommodates a controlled flow of 30 L/min, or 8 USgpm, through orifice size 8, ensuring steady actuator speed at moderate volumes. The maximum operating pressure of 172 bar (2500 psi) defines the upper limit for continuous duty in machine tools or presses. Inlet conditions are kept safe by permitting only 0.7 bar (10 psi) positive pressure or a vacuum no greater than 5 inHg, conditions that prevent cavitation and seal damage. An internal relief valve is preset to open at 175 bar (2500 psi) so excess load spikes bypass to the tank before components are overstressed. Together these limits establish a protected operating envelope that lets system designers match pump output to cylinders, motors, and directional valves without exceeding structural or thermal constraints.
