Built around the project configuration
The Putzmeister PUMI 31-4.79 S combines a 9 m³ concrete mixer, piston pump and four-section placing boom on one truck. This arrangement lets one machine transport, pump and position concrete for small and medium pours where mobilising separate mixer and boom-pump vehicles would take more space and coordination.
The TMM 31-4 boom reaches 30.1 m vertically and 22.9 m horizontally on a net basis. Its standard piston-side pump mode provides maximum theoretical performance of 70 m³/h at 75 bar, while an optional rod-side arrangement increases output to 92 m³/h at a lower 51-bar pressure.
