Felderhalde Tunnel Consortium, Germany

The project:


Wastwater plant for general site facilities


Executing companies:

ARGE Tunnel Felderhalde

Company Alfred Kunz Untertagebau, München

Company Riebel


The problem:


The wastewater contains mud and sand. A robust wastewater pump with vortex impeller was needed.


Our solution:


Deployment of a 80U23.7 with vortex impeller. Installation with connection elbow and guide tubes results in straightforward maintenance.

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.
