Katzenberg Tunnel, Germany

The project:

Treatment and desludging of the process water from the tunnel advance.

Executing company:

Ed. Züblin Umwelttechnik GmbH

The problem:

The fluctuating accumulation of the sludge water from the Katzenberg Tunnel advance is collected in intermediate tanks. The accumulating process water should be pumped into the water treatment plant using submersible pumps.

The solution:

Tsurumi series KTZ contractors' pumps were chosen due to their reliability. Continuous, non-stop operation with high concentrations of sediment is possible with Tsurumi contractors' pumps, securing the operation of the water treatment plant.

In the event of abrasive and corrosive utilization, stronger wear and tear will take place naturally in certain components. With regards to the above application wear and tear can take place mainly in impeller, agitator, suction plate, shaft sleeve, oil ring, mechanical seal, pump casing, strainer, motor casing and discharge coupling. Depending on the working conditions the lifetime of those parts might vary significantly and can be shorter than the legal warranty period.
In this regard, please pay attention to our general terms and conditions that we also send to you by mail on request.
