What Are Concrete Pumps

Background to Concrete Pumps


A concrete pump is a tool for conveying liquid concrete.


Over a period of more than half a century, concrete pumps have slowly taken over from other methods of transferring liquid concrete. A number of different designs of  concrete pump were developed in the first half of the 20th century but it was Friedrich Wilhelm Schwing's company Schwing GmbH which invented the twin cylinder  hydraulic concrete pump in 1957. The principle of this design was adopted by almost all other manufacturers and is still the worldwide standard design.


Demonstration of the pump working The pump works by one piston drawing liquid concrete into a cylinder from a hopper while the other one simultaneously pushes its  concrete out into the discharge pipes. A valve which determines which cylinder is open to the concrete hopper and which one is open to the discharge pipes switches  over each time the pistons reach the end point (see rock valve below and animation left - click to enlarge) and the process continues with the first cylinder now  discharging and the second drawing fresh concrete from the hopper.
