Feature:
1.Variable pump with two axial piston rotary groups in swashplate design for use in open circuit hydrostatic drives.
2.For use in mobile and stationary applications.
3.The pump consists of proven components from the A11VO , A10VO/53 or A4VSO variable pumps.
4.The pump operates under self-priming condition, with tank pressurisation or with charge pump (sizes 190...260).
5.A wide variety of controls are available.
6.Setting of the constant power control is possible via external adjustments, even when the unit is operating (only with power contol).
7.The pump is available with a through drive to mount a gear pump or a second axial piston pump.
8.Output flow is proportional to drive speed and pump displacement and is steplessly variable between maximum and zero displacement.
