When the slurry concentration exceeds 30% and the operating pressure reaches 16 bar, standard knife valves become ineffective. For such conditions, Habermann Aurum Pumpen specialists have developed innovative knife valves, using all their 100 years of experience in the production of slurry pumps. Using the same materials as in the pumps, our valves become even stronger and more durable. The flowing part of the knife is covered with a wear-resistant coating of tungsten carbide, which prevents premature failure of the knife. This unique material in terms of wear resistance and strength makes our knife valves an ideal choice for heavily contaminated and aggressive environments.
