A4VSO Axial Piston Variable Pump Hydraulic Pump A4VO Rexroth Axial Piston Pump A4VSO71HS4V/10R-PPB25N00
Product Overview
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.
Typical Applications
- Metallurgical machinery & forging presses
- Ceramic & refractory forming equipment
- Mining machinery
