A7VO Series 63
Characteristics
▶ Variable pump with axial tapered piston rotary group of
bent-axis design, for hydrostatic drives in open circuit
▶ For use in mobile and stationary applications
▶ Flow is proportional to the drive speed and displace-
ment.
▶ The flow can be steplessly changed by adjusting the
bent axis.
▶ Wide selection of control devices
▶ Compact, robust pump with a long service life
▶ Sizes 28 to 160
▶ Nominal pressure 350 bar
▶ Maximum pressure 400 bar
▶ Open circuit
