This Desulfurization Slurry Pump adopts single‑stage single‑suction cantilever horizontal centrifugal structure with back‑pull‑out design for easy maintenance without removing pipeline. Wetted components including impeller, volute and liner can adopt duplex stainless white iron, high‑chromium alloy, rubber lining or CD4MCu duplex steel to resist combined erosion of solid particles and chloride‑containing acidic slurry.We provide professional FGD‑working‑condition selection calculation, factory performance test report, installation‑operation manual and complete export‑oriented technical documents. OEM service and full set interchangeable wear spare‑parts are available for power‑plant and environmental‑protection project demands.

Product Advantages
Dual Anti‑abrasion & Anti‑corrosion Performance
Multiple optional wetted‑part materials resist both particle scouring and chloride‑acid medium corrosion, greatly extend service life under complex FGD slurry condition.
Back‑pull‑out Convenient Maintenance
Back‑pull‑out structural design, users can inspect and replace rotating assembly without dismantling inlet and outlet pipeline, cut overhaul time greatly.
Optimized Hydraulic Model
CFD‑optimized wide‑flow‑channel impeller, good anti‑cavitation performance, reduce gypsum crystallization blockage risk, keep high operating efficiency for long‑period running.
Reliable Special‑purpose Shaft Seal
Cartridge double‑end mechanical seal matched with flushing water system, effectively prevent slurry leakage, adapt continuous desulfurization circulation duty.
Stable 24‑Hour Continuous Operation
Reinforced heavy‑duty bearing bracket, low vibration and low noise, fully meet non‑stop running requirement of power‑plant desulfurization absorber loop.
Complete Spare‑parts Supply
Full‑range interchangeable wearing spare‑parts in stock, short lead‑time delivery for fast field replacement, reduce system shutdown loss.
Product Customization
Wetted‑part Material
Custom duplex stainless white iron, high‑chromium alloy, rubber lining or duplex steel according to slurry PH, chloride‑ion content and solid‑particle abrasion degree.

FAQ
Q: What common failures will happen during long‑time running of FGD desulfurization slurry circulation system?
A: Main failures contain wetted‑part composite wear‑corrosion, mechanical‑seal leakage, gypsum crystallization blockage, pump efficiency decline caused by impeller wear, which require periodic inspection and maintenance.
Q: What working‑condition parameters should be offered for quotation of Desulfurization Slurry Pump?
A: Please provide required flow rate, total head, slurry solid concentration, PH value, chloride‑ion content, medium temperature and destination port information.
Q: Can this pump be used for absorber tower main circulation loop of large‑scale thermal‑power‑plant FGD project?
A: Yes. We can match large‑flow heavy‑duty model and corresponding anti‑wear‑corrosion material solution according to absorber processing capacity for main circulation service.
