Flue Gas Desulfurization Pump

The Flue Gas Desulfurization Pump from Shi Jia Zhuang Bojin Pump Co., Ltd. is a single-stage, single-suction centrifugal pump designed for abrasive and corrosive slurries in flue gas desulfurization systems. It operates under pH conditions from 2.5 to 13, with chlorine ion concentrations up to 160,000 ppm and solid weight concentrations up to 60%. The medium temperature tolerance is up to 100°C. The pump’s hydraulic design is based on French J S phase technology and uses CAD and CFD optimization to enhance efficiency and reduce energy consumption, which is critical since FGD pumps account for over half the power usage in an absorption tower.

Critical wetted components are constructed from 2605N alloy for the pump casing, cover, and volute, offering excellent corrosion resistance and weldability. The impeller and wear plate are made from Cr30A, a high-chromium white iron with superior abrasion resistance. Unlike conventional designs, this pump eliminates the mouth ring seal, reducing wear points and maintaining hydraulic efficiency over time. The impeller features a front blade structure that deflects large particles away from critical clearances, while its vent design prevents dry running of the mechanical seal by releasing trapped gases. The shaft is oversized and short to minimize deflection, extending seal life under continuous operation.

This pump is primarily purchased by power plants, cement manufacturers, and industrial boilers using wet scrubbing systems for SO2 removal. Buyers typically require long service life and low maintenance due to continuous 24/7 operation. The pump’s back-pull-out design allows rotor removal without disconnecting pipework, reducing downtime. Packaging is standard wooden crate with rust inhibitor, and shipping is usually FOB Tianjin or Qingdao. Buyers should confirm lead time and after-sales support availability, as technical assistance for rebuilds is not guaranteed without prior arrangement.

Shi Jia Zhuang Bojin Pump Co., Ltd. is based in Shijiazhuang, Hebei Province, China, and specializes in slurry pumps for industrial desulfurization systems.
