The problem:
Water removal via sump drainage during downward-moving tunnel mining.
The solution:
Multiple pumps from the KTZ series: 11 x KTZ611 and 6 x KTZ67.5. The special characteristics of Tsurumi pumps, such as an internal mechanical seal, upstream protection sleeve with gasket and an oil lifter allow them to be used in 24-hour on-snore- mode.
