In the mining and metallurgical industries, pumps are also the most used equipment. For example, in the process of underground drainage, mineral processing, smelting and rolling, it is necessary to use pumps to supply water. Mines require water. At the same time, because many mine working areas are below the water table, the removal of water is a major challenge. Water is critical for every mine site - without water the mine could not operate. Pumps are, therefore, one of the most used machines in mines today.
