For the drum generate in mobile concrete mixers A4VTG071, A4VGT090 series.
-Variable axial piston pump of swash plate design for hydrostatic drives in shut circuit
-The circulation is proportional to the push velocity and displacement.
-The circulation boosts as the angle of the swash plate is altered from zero to its greatest price.
-Circulation course adjustments efficiently when the swash plate is moved via the neutral position.
-Two strain-reduction valves are presented on the higher force ports to shield the hydrostatic transmission (pump and motor) from overload.
-The high-pressure aid valves also function as enhance valves.
-The integrated boost pump acts as a feed pump and manage stress source.
-The optimum increase stress is minimal by a built-in increase stress-relief valve.
-Tapered shaft option for direct drive shaft yoke set up.
