The A4VTG series are swashplate-type axial piston variable displacement pumps/motors, specifically designed for the hydraulic systems of concrete mixer trucks. The series covers models such as A4VTG71, A4VTG90, A4VTG145 and A4VTG180. Its structure is suitable for the working conditions of high load, frequent starting and stopping of mixer trucks, providing stable power output and flow regulation capabilities.
Key Performance Parameters
Pressure Range: The nominal pressure is 280 bar, and the peak pressure can reach up to 350 bar, meeting the high-pressure requirements of the hydraulic systems of mixer trucks.
Flow Control: With the design of a variable swashplate, the flow can be steplessly adjusted by adjusting the swashplate angle to adapt to different mixing speed requirements.
Drive Compatibility: It supports hydraulic drive, and the drive shaft can withstand both axial and radial loads, making it suitable for the complex power transmission environment of mixer trucks.
