Pump selection for FGD

The design of the slurry pump is critical to ensure that the abrasive and often corrosive aspects of the slurry do not damage the impeller. In addition, slurries and sludges may contain large amounts of unforeseen solids, which will inevitably clog many types of pumps. Since most centrifugal pump impellers have very tight tolerances on the worm gear, the abrasive (and sometimes corrosive) nature of the slurry will quickly wear down the worm gear and destroy the tolerances. In turn, this causes the pump to lose suction. This can lead to extensive downtime of the slurry pump, as well as expensive maintenance and spare parts.

Is the discharge configuration suitable for abrasive slurries?

Settling slurries are formed by coarse particles, which tend to form unstable mixtures. Special attention should be paid to flow and power calculations when selecting a pump. Most slurry applications consist of coarse particles and therefore have a higher abrasion resistance.

Selecting the right pump for slurries is critical to get the most bang for your buck. Basic pump components, such as the impeller size and design, material of construction, and discharge configurations must be considered to ensure the pump will hold up against the wear caused by an abrasive slurry. Slurry pumps are generally larger in size when compared to low-viscosity liquid pumps and usually require more horsepower to operate because they're less efficient. Bearings and shafts must be more rugged and rigid as well.
