Rexroth Axial piston variable pump A4VSO 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
