V20F 1P9P 38D80 22 074L

The V20F 1P9P 38D80 22 074L hydraulic unit belongs to the Square Vane Pumps series produced by Vickers. It supplies pressurized oil to automated actuators and circuits where consistent flow is required. The pumping element uses a vane mechanism that maintains volumetric efficiency at varying speeds. At 1200 rpm and 100 psi, the pump delivers a rated flow of 9 US gpm, supporting moderate power cylinders. An inlet connection of 1.25 NPT allows direct attachment to common suction lines, while the pressure outlet is threaded .750-16 UNF-2B with an SAE O-ring boss to ensure leak-free discharge. A separate tank return sized .500 NPT provides a low-restriction path back to the reservoir, and the housing tolerates up to 175 bar (2500 psi) so the pump can operate in medium-pressure servo loops.

For mechanical integration, the unit mounts on an SAE A two-bolt flange, simplifying alignment with standard electric motors. The drive end follows a No. 38 splined shaft with an 11-tooth 16/32 DP flat-root profile, giving positive torque transmission without keys. A single lip seal surrounds the shaft to keep oil inside and contaminants out, and a sealed bearing supports radial loads while retaining its own lubricant supply; because the bearing is sealed, routine greasing is unnecessary, which lowers scheduled maintenance requirements in automated cells. Flow stability is assisted by the built-in flow control valve cover, which modulates internal bypass to reduce pulsation at partial load. These features combine to create a compact vane stage suited to automated presses, transfer lines, and other hydraulic machinery.
