CZPT hydraulic PUMP  A4VTG71  with Very good Good quality and Low Cost

Concrete mixer hydraulic piston pump A4VTG71, A4VGT90


Shut circuit
Sequence 32
Sizes seventy one, 90
Nominal force 5800 psi (400 bar)
Greatest stress 6500 psi (450 bar)
Handle device: (HW) Proportional manage hydraulic, mechanical servo, hexagon shaft with lever to the rear.
(EP) Proportional management electric powered, with unexpected emergency actuation and spring return.
For the drum travel in cellular concrete mixers A4VTG071, A4VGT090 sequence.
-Variable axial piston pump of swash plate style for hydrostatic drives in closed circuit
-The circulation is proportional to the generate speed and displacement.
-The circulation raises as the angle of the swash plate is altered from zero to its greatest price.
-Movement route adjustments efficiently when the swash plate is moved via the neutral position.
-Two stress-relief valves are supplied on the large strain ports to protect the hydrostatic transmission (pump and motor) from overload.
-The higher-stress relief valves also operate as improve valves.
-The built-in increase pump acts as a feed pump and management stress provide.
-The maximum enhance strain is restricted by a developed-in boost strain-relief valve.
-Tapered shaft choice for immediate travel shaft yoke installation.
