-When pumping abrasive slurries, it is essential to use wear-resistant components with a high chromium content. But more is not always better - above 25%, the impeller becomes brittle.

Pump selection for FGD

Although the focus of slurry pumps is often on the size and percentage of solids to be pumped, in many applications corrosion resistance is also an important factor in material selection. In such cases, the material chosen must provide adequate resistance to erosion and corrosion.

Again, to meet life cycle cost considerations, pumps should be equipped with large diameter impellers for lower operating speeds and longer wear life, as well as field replaceable rubber liners that can be bolted on for quick maintenance. In a typical coal-fired power plant, two to five pumps will be used in each spray tower.
