ICE railway track Airport Cologne-Bonn
		The Project: Underground railway track to link the Cologne-Bonn airport, Germany Executing companies: Consortium Airport tunnel Cologne-Bonn lot 3 Wayss & Freytag Ingenieurbau AG, E. Heitkamp GmbH, F.C. Trapp AGComplete dewatering (24h-duty) carried out by: Smet GWT N.V., Dessel, Belgien Biergans Pumpen-Vertrieb GmbH, Duisburg
The Problem: Open dewatering by means of submersible pumps. Our Solution: The groundwater generated is pumped off by several submersible pumps for abrasive water. 24-h on-snore-operation must be ensured. Currently a total of twenty KTZ21.5 and ten KTZ32.2 is in operation.

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, suction plate, shaft sleeve, oil ring and mechanical seal. Depending on the working conditions the lifetime of those parts might vary significantly and can be shorter than the legal warranty period.
