The V10 1P4P 38C20L pump belongs to the Square Vane Pumps series manufactured by Vickers for hydraulic automation circuits that need steady fluid delivery. Each revolution moves 0.80 in³ of oil, which establishes the volume displaced per shaft turn. At 1200 rpm and 100 psi the unit produces a rated flow of 4 US gpm, matching common low-speed power packs. The housing tolerates up to 172 bar (2500 psi) so the pump can operate in medium-pressure systems without overstressing internal components. Counter-clockwise rotation viewed from the shaft end suits installations where the prime mover turns in that direction. A 1.00 in NPT inlet thread accepts standard suction lines for quick plumbing. The outlet is kept in line with the inlet to simplify manifold layouts, and its 0.500 in NPT thread secures pressure piping without adapters.
A 2-bolt SAE A mounting flange positions the pump on common motor face pads used in mobile and industrial frames. Bolt holes sized at 0.44 in allow Grade 5 fasteners to clamp the casing firmly, while a 3.250 in pilot centers the body to minimize shaft misalignment. The shaft projects 1.269 in beyond the front face, providing enough length for coupling hubs. Power transfer relies on an 11-tooth, 16/32 DP, 30° PA involute spline that resists torsional loading better than keyed shafts. A major diameter of 0.749 in defines the outer spline fit, and a 0.590 in minor diameter sets the root size to maintain tooth strength under peak torque.
