Reitersberg Tunnel, Germany

The Project:

Reitersberg Tunnel of the Ebensfeld–Erfurt ICE rail link


Contractor:

Alfred Kunz Untertagebau

Swietelsky Tunnelbau

Leonhard Weiss


Tsurumi support:

Christian Kulik (Field Sales)


The Problem:

The 2975 m long tunnel is being cut using mining methods. After the snow melted, the water incidence in the tunnel suddenly rose to a maximum of 20 litres/second. The medium was made highly abrasive by its slurried stone content.


The Solution:

Massive drainage pump of types KTZ411 and KTZ611 (11kW) transport water over a distance of 500m to 1000m. The KTZ series is the perfect contractors' pump due to its good performance. The replacement of wearing parts is very simple. After training by qualified Tsurumi staff, all maintenance can be done independently on site.


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.
