Mining Machinery Parts A4V40 A4VG71 A4VG28DA A4VG90 A4VG180 A4VG125 A4VG250 Axial Piston Pump Variable Pump for Rexroth
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
- Marine & offshore hydraulic systems
- Oil & gas industry
- Heavy machine tools, construction equipment
- Injection molding machine, test bench hydraulic station
