Features
--Variable pump with two axial piston rotary groups in swash-plate design for use in open circuit hydrostatic drives
--For use in mobile and stationary applications
--The pump consists of proven components from the A11VO(RE 92500), A10VO/53 (RE 92703) or A4VSO (RE 92050) variable pumps
--The pump operates under self-priming condition, with tank pressurisation or with charge pump (sizes 190...260)
--A wide variety of controls are available
--Setting of the constant power control is possible via external adjustments, even when the unit is operating (only with power contol).
--The pump is available with a through drive to mount a gear pump or a second axial piston pump
--Output flow is proportional to drive speed and pump displacement and is steplessly variable between maximum and zero displacement
