Drainage of a shearing trench
Biergans Pumpen-Vertrieb GmbH
Badische Stahlwerke GmbH, Kehl
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.
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.
