FGD Pumps' Key Design Features

Back Pull-Out Structure: This allows maintenance crews to remove the rotating assembly without disconnecting the suction or discharge piping, significantly reducing downtime.

Large Diameter, Slow-Speed Impellers: To minimize erosion, FGD pumps utilize large impellers that move vast volumes of slurry at lower RPMs. This reduced velocity extends the lifespan of internal components.

Advanced Metallurgy: Wetted parts are often cast from A49 or natural rubber linings, providing the high-hardness needed for abrasive gypsum and the acid resistance required for low pH environments.

Specialized Slurry Seals: Integrated mechanical seals, often utilizing silicon carbide faces, operate without external flush water to prevent dilution of the absorber slurry while keeping abrasive particles out of the motor.
