Excavator A10VO140EZ4 A10VSO45 A10VSO63 A10VSO71 A10VSO100 A10VSO140 Rexroth Piston Hydraulic Pump
The A10VSO series is swashplate-type axial piston variable pump specially engineered for open-circuit hydrostatic transmission systems. Flow output is linearly proportional to drive speed and geometric displacement; stepless flow regulation is realized by adjusting swashplate tilt angle. It features compact structure, high power density, ultra-low noise, long service life and comprehensive control modules, widely adopted in mobile machinery and industrial high-pressure hydraulic systems.
