Pipe heading Aakerfährstraße, Germany

The Project:


Pipe heading DN1200 Aakerfährstraße, Duisburg, Germany

Executing company:

Siebert Bauunternehmung GmbH, Bebra



The Problem:


Lowering and maintaining the groundwater table. At the beginning several medium-sized pumps were employed which burdened the mains electricity supply excessively. As the river Rhine flows past at a distance of 200m the groundwater could only be lowered with difficulty.


Our Solution:


A pump of type KRS2-89 incl. hosepipe and 300m drainage in the form of a pipe. Draining of the excavation for the whole construction period. Operation of the pump in 24-hour pumping on snore mode.

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.
