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. WATER TREATMENT DUCHTING PUMPEN has worked in desalination with high-pressure...

DUCHTING'///////, Fields of Application Pumping abrasive and / or corrosive liquids. ■ Flue gas desulfurization ■ Incinerators ■ Water treatment ■ Seawater desalination Materials Volute casing: Impeller: Wear plate: Shaft: Shaft sleeve: Mechanical seal: SICcast® / EN-GJS-400-15 (GGG40) SICcast® SICcast® 1.0503 (C45) 1.4301 (1.4462) Silicon carbide (SIC) Technical Data Pump Size: DN 400 to DN 1000

The cartridge mechanical sea DUTEC®-C consists of a rotating and a stationary unit which are assembled separately. This derivative of the established DUTEC® mechanical seal was especially geared towards this pump series and for the conveyance of corrosive and abrasive liquids. Bearings Oil lubricated antifriction bearings. Cast iron bearing housing provided with maintenance free labyrinth seals to avoid oil leakages. Casing Cover Made of SICcast® mineral cast/ EN-GJS-400-15 (GGG40).

Operational Experience Pictures of a Duplex Stainless Steel impeller which has been replaced by a SICcast impeller.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...

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...
