Trapp GmbH Cologne, Germany

The project:

New construction of canal made of site-mixed concrete and liner renovation, Viehtrift, Cologne

Executing company:

F. C. Trapp Tief- und Straßenbau Köln GmbH

The problem:

Transferring collecting wastewater during the 14 months of construction.

Our solution:

Eight type 50C2.75 sewage pumps with cutting mechanism were used.

The cutter blades chop up the collecting solid material to prevent clogging. Operational safety was of the utmost importance.

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.
