A4VSO series is a swashplate design axial piston variable pump, specially developed for hydrostatic drives in open hydraulic circuits. Output flow is proportional to rotating speed and displacement; stepless flow adjustment can be realized by changing swashplate angle. With modular construction, high power density and reliable performance, it serves heavy-duty industrial and mobile hydraulic systems.
