		The Project: Construction of the road tunnel B236n in Dortmund-Berghofen Executing company: Bilfinger Berger AG   The Problem: Open dewatering during the underground tunnel heading and also cut-and-cover work with the aid of submersible pumps.

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, 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 conditions of sales (www.tsurumi-europe.com/english/GCS.htm) that we also send to you by mail on request.
