Brueninghaus Hydromatik CZPT A4VTG pump
Concrete mixer hydraulic piston pump A4VTG71, A4VGT90


Closed circuit
Sequence 32
Sizes 71, 90
Nominal pressure 5800 psi (four hundred bar)
Optimum pressure 6500 psi (450 bar)
Management device: (HW) Proportional handle hydraulic, mechanical servo, hexagon shaft with lever to the rear.
(EP) Proportional manage electric, with emergency actuation and spring return.
For the drum drive in cell concrete mixers A4VTG071, A4VGT090 sequence.
-Variable axial piston pump of swash plate design for hydrostatic drives in shut circuit
-The stream is proportional to the drive velocity and displacement.
-The circulation raises as the angle of the swash plate is modified from zero to its optimum value.
-Stream direction changes effortlessly when the swash plate is moved through the neutral situation.
-Two force-relief valves are presented on the higher stress ports to shield the hydrostatic transmission (pump and motor) from overload.
-The higher-stress reduction valves also purpose as improve valves.
-The built-in enhance pump acts as a feed pump and control pressure provide.
-The optimum enhance pressure is minimal by a constructed-in boost force-relief valve.
-Tapered shaft option for direct travel shaft yoke installation.
