The project:

Drainage of a shearing trench

Executing companies:

Biergans Pumpen-Vertrieb GmbH

Badische Stahlwerke GmbH, Kehl

The problem:

Pumping of abrasive and cinder-loaded water Water carrying cinders must be conveyed to a height of about 4 m, where it is reintroduced to the water circulation. The water is cooling water for the rolling process, which runs off into the shearing trench

over different paths. In the trench, there is a gravel curb to catch fragments from a shaping shear.

Our solution:

It was not possible to devise a normal drain for the water at a reasonable cost. The installation of a powerful, robust pump was thus the only practical solution.

Two model GPN3-80 pumps were provided, with one pump on standby. The pump in use is operated around the clock, seven days a week, without visible wear.

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.
