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
