Hydraulic Piston Variable Pump A4VTG A4VTG71 A4VTG90 A4VTG71HW/32R-NSD10F001S A4VTG71HW/32L-NLD10F001S

A4VTG is a closed loop axial piston variable displacement pump designed specifically for mobile machinery such as mixer trucks. The core parameters are as follows:

1, Basic specification parameters
The mainstream displacement covers 28-90 cm ³/r, among which the most commonly used A4VTG90 model has a speed of up to 1500RPM and a total weight of about 60-65kg, suitable for hydraulic transmission systems of various concrete mixer trucks.

2, Pressure performance parameters
The nominal pressure is 400 bar, and the peak pressure can reach 450 bar. It is suitable for the high-pressure transmission requirements of heavy-duty mixer trucks and can effectively prevent system overload.

3, Structure and Performance Characteristics
Adopting a variable structure of inclined disc axial piston, the flow rate is proportional to the driving speed and displacement, and can be infinitely adjusted. The inclined disc can smoothly change the direction of liquid flow by passing through the center position. It is equipped with a built-in oil replenishment pump and pressure cut-off valve, and the standard overflow valve also has the function of an oil replenishment valve, which is suitable for scenarios such as mixer trucks, steel mills, and sewage ships.
