Tunnel Burgholz, Wuppertal

The project:

Construction of a tunnel for road traffic

Executing companies:

Consortium Tunnel Burgholz

Baresel AG, NL Tunnelbau

G. Hinteregger & Söhne Baugesellschaft m.b.H

The problem:

Pumping off the water arising during underground tunnel heading.

Our solution:

Application of 25 Tsurumi submersible waste water pumps of series KTZ and KTV and KRS with agitator.

KTZ45.5 in snore mode installed in traverse heading between the south and the north tunnel.
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.
