How does a concrete pump work?

Concrete pumps transport wet mixed concrete from the mixer to the pour location. The wet concrete from a mix truck is discharged into a hopper where an agitator keeps it moving and flowing into the piston pump’s twin cylinders.

One cylinder pushes the concrete into the pipeline on the forward stroke, while the other cylinder draws concrete from the hopper on the return stroke. The pistons in both cylinders move in opposite directions to keep the pressure consistent and the concrete flowing freely.
