Pumping starts with the pouring of concrete from the ready mix truck into a tank large enough to hold a small amount of fresh concrete. In the mixing drum, the mixer allows fresh concrete to flow smoothly into the pumping cylinder. Concrete piston pump works on the same principle as a twin piston engine in which a cylinder removes concrete from the cylinder on its rotational stroke. And another is pushed into the line The pistons in both cylinders work in opposite directions, so there is constant pressure on the concrete in the line and in continuous flow. The piston operated hydraulic cylinder is driven by the hydraulic pump. The synchronization valve holds the concrete from two cylinders to a drain pump.
