On-site training, Vianden, Luxemburg

The Project:


Extension of the pumped storage power station at Vianden by an 11th machine, Lot 1 – Structural installations, Luxemburg


Companies involved:

Ed. Züblin AG, IU Directorate – Tunnel Construction, Stuttgart

Strabag AG, IQ Directorate, Vienna

Jäger Bau GmbH, Schruns


The largest pumpe storage power station in Europe in the township of Vianden in Luxemburg, with a peak capacity at the present time of 1,100 MW, is being extended by a further turbine with a capacity of 200 MW.

The construction work includes the carcasse work for the cavern, as well as the access galleries, shafts, and intake and outlet structures.


The Problem:


Tunnel construction in particular is where pumps are in most cases required to work under especially difficult conditions. This is why the sites have their own workshops, where machinery and equipment can be repaired and maintained. In this situation, simple maintenance of the pumps is an important consideration in ensuring long and trouble-free operation.


The Solution:


Training the workshop personnel, with the aim of enabling them to carry out the maintenance and repair of Tsurumi pumps themselves.

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.
