The project:

two-lane railway tunnel, tunnel length: 1.160 m

Executing companies:

Per Aarsleff Bygg- och Anläggnings AB

The problem:

Drainage with the help of submersible pumps in preliminary section and during the tunnel drive.

Our solution:

Type KTZ32.2 and KTZ45.5 pumps are used.

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.
