Line Length

Friction between the pumped concrete and the internal pipeline wall means that the line length directly affects the line pressure requirement. The longer the pipeline length, the more steel pipe, with its smooth interior surface, becomes desirable.

Weighing the options:

  • The convenience of easy access for truck mixers must be weighed against the desirability of locating the pump closer to the placement point.
  • Consider using two lines and two pumps when there is a large distance between the pump and the furthest placement point. The end of the first pump feeds into the hopper of the second pump. This may operate more efficiently than a single system operating at excessive line
