Pumping of concrete: Understanding a common placement method with lots of challenges
Truck mounted dual piston pumps are commonly used for concrete pumping. Invented in 1931, and with subsequent improvements, these pumps utilize an alternating and synchronized movement of two pistons connected to a valve system to push the concrete through the pipe system [18]. While one piston is pushing the concrete into the pipes, another piston is filled with concrete by suction. A stepwise control of pressure and flow rate is nowadays typically enabled through a remote control system.
