Key Functions of FGD Pumps

Absorber Recirculation: The most vital function; these pumps continuously circulate limestone or lime slurry to the top of the spray tower. This ensures a dense mist that reacts with upward-moving flue gas to neutralize pollutants.

Slurry Transportation: They move abrasive and corrosive gypsum slurries from the absorption tank to dewatering systems, facilitating the creation of usable byproducts.

Reaction Maintenance: By controlling flow rates, FGD pumps maintain the chemical equilibrium and temperature within the tower, ensuring maximum SO₂ removal efficiency.

System Protection: Engineered with duplex stainless steel or specialized rubber linings, these pumps are built to survive the high-chloride, low-pH environments that would destroy standard equipment.
