222AK00030B

The 222AK00030B is produced by Vickers for the X20 Mobile Piston Pumps series. It provides variable flow for hydraulic actuators in mobile automation circuits through a displacement of 28.0 cm³ per revolution (1.71 in³ per revolution), enabling moderate output within compact envelopes. The displacement is the standard option, avoiding changes to swashplate geometry and simplifying spare-part selection. A pressure-compensated, load-sensing controller with a left-side LS port, identified as the PCLS WSAE configuration, adjusts the swashplate to maintain target pressure while responding to load demands. Clockwise, right-hand rotation matches common engine PTO direction on mobile machinery. Power is transmitted through a 2-bolt B spline shaft with 13 teeth at a 16/32 pitch, providing positive torque transfer to the rotating group. A fluorocarbon rubber shaft seal protects the bearing cavity from external contamination and retains case fluid at elevated operating temperatures typical of off-highway equipment.

For service connections, a .875-14 SAE O-ring case drain is placed on the bottom so internal leakage oil can be routed directly back to the tank and avoid aeration. A .4375-20 SAE O-ring diagnostic port allows technicians to connect gauges and verify case pressure during troubleshooting without disturbing main lines. No auxiliary mount is present, so the housing cannot accept piggyback pumps or mechanical take-offs, reducing overall package length. The control section carries no special features, keeping adjustment behavior predictable and easing setup on standard load-sense circuits. Likewise, the pump portion lists no special features, meaning the core hardware remains unmodified for dedicated OEM requirements. These connection details and omissions ensure straightforward installation, minimize accessory components, and focus the unit on reliable load-sensing flow delivery.
