Description  

Shut circuit
Collection 32
Dimensions 71, 90
Nominal pressure 5800 psi (400 bar)
Greatest force 6500 psi (450 bar)

For the drum travel in cell concrete mixers A4VTG071, A4VGT090 series.
-Variable axial piston pump of swash plate style for hydrostatic drives in shut circuit
-The movement is proportional to the drive speed and displacement.
-The movement raises as the angle of the swash plate is altered from zero to its highest worth.
-Movement path modifications efficiently when the swash plate is moved via the neutral position.
-Two pressure-reduction valves are provided on the substantial force ports to safeguard the hydrostatic transmission (pump and motor) from overload.
-The high-strain reduction valves also function as enhance valves.
-The integrated increase pump functions as a feed pump and control pressure source.
-The highest enhance force is restricted by a created-in increase pressure-reduction valve.
-Tapered shaft option for immediate generate shaft yoke installation.
