Technical information
Models:A7VO28/A7VO55/A7VO12/A7VO80/A7VO107/A7VO160/A7VO200/A7VO172/A7VO250/A7VO355/A7VO500
Rexroth Axial piston variable pump A7VO Series
Nominal pressure 350 bar
Maximum pressure 400 bar
Open circuit
-Variable pump with axial tapered piston rotary group of bentaxis design, for hydrostatic drives in open circuit
-For use in mobile and stationary applications
-The flow is proportional to the drive speed and displacement.
-The flow can be infinitely varied by adjusting the bent axis.
-Wide selection of control devices
-Compact, robust pump with long service life
Our pumps are mainly used for construction machinery, geological drilling equipment, special vehicles,mining machinery, lifting and transporting equipment, cranes, ship machinery, agricultural and forestry machinery, and so on.
