Jun 11, 2019· One piston draws the liquid concrete from a hopper and into a cylinder while at the same time, the other piston pushes concrete out into the discharge pipes. A valve determines which piston is open to the concrete hopper and which is open to the discharge pipes by switching over each time the pistons reach the end of the cylinders.Estimated Reading Time: 5 mins
Designing The Mix
The concrete piston will push concrete from the concrete cylinders through the S-Tube and out to the concrete pipe and concrete hoses. Next, the pump switches at the end of the stroke, causing the s-tube valve to shift to the other concrete cylinder which has sucked and filled the cylinder with concrete, starting the next cycle.
