Today, mobile fresh-concrete pumps can be found on almost every construction site. These pumps all have one common feature: interruptions in delivery. The discontinuous output flow rate of the fresh-concrete pumps has a negative effect on various aspects of the operation. In order to solve this problem, the Institute of Mobile Machinery Division at the Karlsruhe Institute of Technology in cooperation with Putzmeister Engineering has developed a new concept of a mobile fresh-concrete pump with constant delivery behavior.


Depending on the different designs of mobile concrete pumps, delivery heights of up to 606 m [1], delivery pressures of 220 bar [2], and output flow rates of 200 m3/h [3] can be achieved. These pumps, which have been established on the market for decades, all work based on similar principles and have characteristic advantages and disadvantages. A disadvantage that all of them have in common is an interruption in delivery which is inherent to their functional...
