Working Principle
This is a single-volute, single-stage, single-suction centrifugal pump with back-pull-out construction. Process fluid enters axially, gains energy from the rotating impeller and discharges radially. The back-pull-out design allows impeller, mechanical seal and shaft assembly removal without disconnecting pump piping. Pump casing is made of super-low-carbon duplex stainless steel CD4MCuN, while impeller and wear plates adopt high-chromium alloy Cr30A to withstand erosion and high-chloride corrosion. Mechanical seal options ensure reliable sealing under harsh corrosive conditions.
Application
Thermal Power & FGD: Recirculation of process slurry for limestone-gypsum wet flue-gas desulfurization absorber towers.
Chemical & Environmental Protection: Transfer & circulation of corrosive, high-chloride, high-solid-content chemical slurries and acid-alkali media.
Metallurgy: Handling abrasive corrosive slurries for smelting flue-gas washing and purification.
General Industry: Transport of corrosive high-solid-content suspensions and mineral slurries for mines and process plants.
