FGD pump is single stage, single suction horizontal centrifugal pump. It is mainly used as the circulating pump for absorption tower in FGD system in Power Plant.
Heavy-Duty Flue Gas Desulfurization Slurry Pump for Power Plants and Industrial Scrubber Systems
The DT Series FGD Pump is a horizontal centrifugal slurry pump designed for demanding Flue Gas Desulfurization (FGD) systems in power plants and heavy industrial environments. It is engineered to handle large-capacity abrasive and corrosive slurries such as limestone and gypsum under continuous operation conditions. The series covers a wide performance range with flow capacity up to 9,700 m³/h, head up to 88.6 m, and high operating efficiency, making it suitable for both medium and ultra-large FGD circulation systems. With robust hydraulic design and wear-resistant construction, the pump ensures stable performance even in highly corrosive wet scrubber conditions.
DT Series FGD Pump is widely used in thermal power plants, steel mills, cement plants, and waste-to-energy facilities where reliable slurry transport is critical for emission control and desulfurization efficiency.
