Pumping off abrasive ceramic slurry during production.
Nord Ceram Fliesenproduktions und Vertriebs GmbH & Co. KG, Bremen
Large amounts of water are used to wash adhesive clay residues from the treatment aggregate. The washing water, which carries clay slurry, collects in the ground cavity and has to be pumped back out of the cavity. The problem is that the clay settles, forms sediment and is very difficult to pump. The pumping of abrasive and corrosive fluids subjects the parts to great wear, is prone to failure and is a costly venture. Not all pump technologies are able to handle this.
Use of type KTV2-37 submersible pumps for pumping off abrasive materials.
The pump housing is made completely out of nitrile rubber and has no problem resisting ceramic slurries.
