Since the beginning of flue gas desulphurisation in Germany in 1982, DÜCHTING PUMPEN has been engaged in the design and construction of circulation- and suspension pumps. DÜCHTING PUMPEN has made a name for itself in this area with many deliveries throughout the world. Being a market leader, DÜCHTING PUMPEN can supply and build any sizes required and can offer tailor-made solutions to its customers. In addition, it is possible for us to build pumps in all kinds of duplex stainless steel grades and in a SICcast® material whose life exceeds all expectations. Components such as wear plates, impellers, or even the complete hydraulic section can be made of this ceramic material, which can only be obtained from DÜCHTING PUMPEN. Because of its unlimited corrosion resistance and its extremely high wear resistance, life-cycle costs - for example those of the MC/MCC series - are reduced to an absolute minimum. In the meantime, we have been able to design pumps of the MC/MCC series – and also single impellers and wear plates – with operating lives of more than 70,000 hours.
By using the DÜTEC® single acting mechanical seal, the entire pumping chamber is kept free of metal. Thanks to its external springing, the DÜTEC® single acting mechanical seal that was especially developed at DÜCHTING PUMPEN for the transportation of solids, will ensure that there will not be any leaks whatsoever, regardless of the operating conditions.

For flue gas purification in waste-fuelled power stations, there are higher requirements with respect to the material's resistance to corrosion as well as to wear. Duplex stainless steels are usually not adequate and normal industrial plastics are subject to increased abrasive wear.
SICcast®, however, can fully meet these requirements: Here, too, DÜCHTING PUMPEN can offer a large range of pump sizes and has a comprehensive list of references.
