Product Overview

FLUE GAS DESULFURIZATION The flue gas cleaning in Germany started with the adoption of the „GroR>feuerungsverordnung“ - a regulation for open fire - in 1982. From the very beginning DUCHTING PUMPEN took part in this business and today has one of the largest populations in European power stations. With the development of the material SICcast® now almost every FGD pump is built completely in SICcast®. Through this unique and innovative technology our products are increasingly favored beyond the borders of Europe.

Operational Experience Pictures of a Duplex Stainless Steel impeller which has been replaced by a SICcast impeller. Highly wear resistant Fully corrosion resistant Easy quality control of castings Lower noise & vibrations compared to metal Heavy wear after 11,000 operating hours No wear after 24,000 operating hours Comparison with Metal Miller Wear Test In regards of resistance, metals are only a compromise between conflicting requirements. Standard test method for determination of slurry abrasivity. Having only corrosion and no abrasion, it will be also possible to use hastelloy. It’s the same...

Life-Cycle-Costs Average life cycle costs for industrial pumps. Evaluating the Life-Cycle-Costs will identify the most financially attractive alternative. The initial purchase price is a very small part of the life cycle cost for high usage pumps. Minimizing energy consumption and plant downtime have a big influence on the total LifeCycle-Costs. Energy costs DÜCHTING PUMPEN offers a wide range of impeller sets for high efficiencies.► ► high efficiency leads to low energy costs Maintenance costs Robust design leads to long lifetime of the pump parts.► ► low wear leads to low maintenance work and...
