The V20F 1P11P 38D8H 22L pump is part of the Vickers Vane Pumps series and supplies controlled hydraulic flow for automated equipment. Its displacement is 36.4 cm³ per revolution, defining the volume moved on each cycle. This figure supports a ring capacity of 11 US gpm so circuits receive a steady supply under normal load. The unit is built for left-hand (counter-clockwise) rotation to match drives that turn in that direction. A 2-bolt SAE A flange allows direct mounting to standardized power pads and simplifies alignment. Fluid enters through a 1.25-inch NPT inlet and exits the pressure side through a .750-16 UN-2B port, establishing convenient threaded connections for suction and discharge lines.
The cover is the flow-control-valve style, enabling in-body adjustment of delivery without external throttling hardware. Internal bearings are sealed to block contaminants and extend operating life. A single-lip shaft seal contains the working fluid, and the seal package is classified as standard for compatibility with common service kits. Drive torque is transmitted through an 11-tooth 16/32 DP flat-root side-fit spline that mates with matching couplings. Return oil is routed to the reservoir by a 0.500-inch NPT tank port positioned for straightforward piping.
