Cologne/Bonn airport connection, Germany

The Project:


Connection of the newly built road for Cologne/Bonn airport

Executing Company

Heitkamp GmbH, Wayss&Freytag AG,

Trapp GmbH


The Problem:


Maintainance of water level in a rainwater storage basin at the building site.


Our Solution:


Installation of 2 submersible pumps KTVE21.5 and KTVE22.2. The advantage here is in the integrated level control unit via electrodes. A separate floater cable does not have to be laid. The space required is determined by the diameter of the pump. In contrast to floaters, electrodes do not have to be readjusted. The level can be varied without any difficulty by mounting a screw.

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.
