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.

MCV Design Single-stage vertical centrifugal sleeve-bearing pump. ■ Handling of abrasive and corrosive liquids ■ Vertical mixed flow pump designed for desalination plants to work as intake pump ■ Suitable for a wide flow range ■ Suction flange: vertical ■ Discharge flange: radial ■ SICcast® - inlet housing and diffusor withstand hard particles ■ Shaft sealing by a single acting mechanical seal ■ Polygon sleeve bearings support long shafts and protect against vibration. Radial bearings made of SiC on SiC ■ The modular design makes it possible to produce extremely large pumps at low costs

DUCHTING'//////////////////, Fields of Application Handling of abrasive and corrosive liquids. ■ Seawater intake ■ Water treatment plants ■ Cooling in power plants ■ Salt water applications Materials All wetted parts (except shaft) are made of metal free materials to avoid corrosion totally. Different shaft materials available according to the application requirements. All hydraulic parts and the discharge bend are manufactured in SICcast®. Anti-corrosion lifetime guarantee for all SICcast® parts in seawater applications.

Pump Type MCV Inlay X Discharge bend fully lined with SICcast® - minimises abrasion and maximises corrosion resistance. Intermediate / Riser Pipe 554.5 Modular design of shaft and rising main provides flexibility in length. Bowl with Guide Vanes 112 made of SICcast® - resistant to hard particles.

Technical Features Motor Connection Flexible connection for different motor sizes. Reliable thrust bearing. The lubrication system ensures a long bearing life time. Single acting mechanical seal by standard,433 gland packing also available. Radial Bearing Optimized shaft guidance for minimized vibrations. Impeller SICcast® mineral cast mixed flow impeller with spatially curved vanes, optimized to efficiency. Keyed to the shaft and bolted from the bottom. Additional radial bearing close to the impeller. Teileverzeichnis / part list designation pump bowl discharge casing bellmouth clamping ring...

The unique Material - SICcast® Epoxy resin Silicon carbide Polished section scale 500:1 1. Bonding Agent 2. Bonding Agent that has penetrated into a SiC grain 3. ground, polished SiC grain Mineral cast SICcast® Established in the mid-nineties, SICcast® is growing together with our customers. Started with the casting of several pump parts for the MC series and afterwards for the MCC series of affiliated company DÜCHTING pumps. Silicon carbide (SiC) in a special mixture with Epoxy resin cast into precision moulds under vacuum. Fittings are machined with diamond tools. Thanks to the temperature-controlled...

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...
