The mandate:
Extracting raw materials from the ground creates a lot of waste that is harmful for the environment. It also creates holes in the ground that limit the amount of material that can be extracted.

Pumpaction’s added value:
The Putzmerister HSP2180 pumps and the HA75 hydraulic power pack allow the paste containing the mine’s waste to be pumped back into the galleries to fill them at a rate of 40m³/h at 35 bar. This equipment solved the problems caused by the harmful waste of the mine, while allowing the maximum amount of raw material to be extracted from the mine. The “C” head of the pump allows the paste to reach the most remote parts of the mine.
