Rupp gravel plant, Dillingen, Germany

The project:


Preparation/clarification of rinse water from gravel processing


Executing company:

Josef Rupp GmbH&Co. KG


The problem:


The condensed slurry from the clarification tower is pumped into the buffer silos of the chamber filter press. The consistency of the medium ranges from fluid to a thickly flowing mud. Lime is added to the mud for conditioning.


Our solution:


The high proportion of abrasive sediments could not be pumped satisfactorily using the pumps in use until now. The result was a high degree of wear and replacement part costs.

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.
