Ikitelli underground railway tunnel,
Istanbul, Turkey

The project:

Construction of a 15 km long underground tunnelusing a TBM.

Executing company:

Taisei Corporation, Japan

The problem:

Sludge and muddy water were causing major problems during construction and had to be pumped off.

Our solution:

All the pumps needed to dewater the site were supplied by Tsurumi. A large number of LH, KTZ, KRS, KTV and LB pumps were used to keep the site dry.

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.
