Main Features

1) The large-diameter and big-flow valve group, small in size and light in weight , is well known for its high response speed and less power loss.

2)The new generation of electronic control system, which adopts an energy-saving control technology, is safe and reliable and enjoys a high maintainability. The fuel consumption during concrete pumping operation is about 0.5L/m3

3) The adoption of fault self-diagnosis system,CAN bus and special controller applications ensures that the operator can get the fault information and solve the problem in time, greatly improving the reliability of the electrical system.
