The AEC018R50AAL1AA261400000200100CD01B hydraulic pump belongs to the X20 Mobile Piston Pumps series manufactured by Vickers. It delivers pressure-compensated flow for hydraulic automation on mobile equipment. The pump displaces 18.0 cm³ per revolution, supplying a predictable oil volume each cycle. Right-hand clockwise input shaft rotation permits direct coupling to engines that follow standard drive orientation, and the front mounting interface uses a 2-bolt A flange with a 9-tooth 16/32 spline for secure power transmission. A fluorocarbon rubber shaft seal keeps fluid contained while withstanding high oil temperatures. Flow control is handled by a PCLS WSAE load-sense controller with its LS port on the left side, allowing demand-based regulation in steering or implement circuits.

The housing is supplied without an auxiliary output shaft, so additional pumps or accessories cannot be mounted in line. An external manual adjustment preset at maximum limits the displacement, letting technicians reduce flow if required. There is no secondary compensator setting, simplifying the control scheme when only primary load-sense regulation is needed. A top-mounted .75-16 SAE O-ring drain port returns case oil to tank and prevents excess pressure at the shaft seal. Two .4375-20 SAE O-ring diagnostic pressure ports are shipped plugged but can be opened for gauge installation during troubleshooting. These layout and service features support compact, maintainable integration in forklifts, harvesters, and other mobile machinery.
