How does a REED Concrete Pump work?

Reverse pumping links the concrete piston in the suction stroke and S-Tube valve to suck concrete from the s-tube instead of the hopper. As a result, the concrete piston pumps concrete into the hopper. The power for operation of the concrete pump is provided by the engine, which drives the hydraulic pumps. All functions for operation of the
