TLB Duplex stainless steel desulfurization pump

Designed for heavy-duty flue gas desulfurization (FGD) and other slurry-handling applications, this TLB series duplex stainless steel desulfurization pump is a single-stage, single-suction horizontal centrifugal pump engineered for high efficiency, long service life and minimal maintenance.

Key features

• Robust construction for abrasive and corrosive slurries: flow-wetted components available in duplex stainless steel grades (e.g. 2205, 2507, 2605, Cr30A, CD4MCu) to resist corrosion and erosion in aggressive environments.
• High solids tolerance: handles media with up to 40% solids content; designed to avoid clogging and pass particles of varying hardness and softness.
• Wide operating temperature range: suited for process temperatures from -20°C to +150°C.
• Durable sealing: mechanical seal made from non-pressure sintered silicon carbide for extended seal life in abrasive and corrosive services.
• Efficient hydraulic design: single-stage centrifugal impeller for stable performance across a broad duty range.

Applications

• Flue gas desulfurization systems: wet limestone/gypsum, double-alkali, circulating fluidized bed, seawater desulfurization, ammonia desulfurization.
• Industrial slurry transfer: lime slurry, cinder/slag liquids, waste acid, sewage and other abrasive or corrosive slurries.
• Any process requiring reliable transfer of acidic, alkaline or saline slurries with high solid content.

Performance & sizing

• Nominal diameters: DN25 – DN500
• Flow range: 1.6 m3/h – 3,000 m3/h
• Head range: approximately 5 m – 125 m (model-dependent)

Benefits for B2B operators

• Reduced downtime and lower lifecycle cost through improved material selection and seal durability.
• Flexible specification options (materials and sizes) to match site conditions and slurry chemistry.
• Suitable for retrofit or new-build FGD plants and other industrial slurry-handling installations.

Typical model example: TLB40-32-125. For pump selection, performance curves, materials of construction confirmation and accessory options (shafts, couplings, baseplates, controls), specify duty point and slurry characteristics so the correct TLB configuration can be supplied.
