■Flow rate:Q=700~14000 (m³/h)
■Total head:H=15~63 (m)
■Speed:n=420~980rpm
■S.g.:γ ≤1.5
■Temperature:T=0~120℃
■Pump diameter:300~900mm
■Elaborately designed based on the characters of flue gas desulfurization of thermal power plant to meet the requirements of a facility below 1000 MW.
■Hydraulic models are CFD optimized to have excellent performance of anti-cavitation.
■Specially designed mechanical seal for flue gas desulfurization process.
■The impeller position can be adjusted by the bearing housing,this brings a shortcut to recover the pump performance under a slightly abrasion.
■Axial adjusting structure to maintain the distance between impeller and front cover plate to keep a high efficient operation.
■The specially designed anti-corrosive and anti-abrasive duplex stainless white iron for FGD process,which has the advantages of both duplex stainless steel and white anti-abrasive iron alloy.
■All metal materials for pump set,without any lining rubber or other high polymer material.
■Pump casing adopts duplex stainless steel of 2605N and 2205,which have excellent resistant performance of chloride ions and sulfate ions,and therefore is the first choice of desulfurization pumps.
■Front and back open structure,the rotary part can be removed from the casing without dismantling the pipelines.
■Cartridge mechanical seal with internal or external flushing plans.
■The bearing part is back pull structure,which is assembled in the bearing housing.
■Transmission: directly coupled and gear box drive.

■Material of flow passage components based on pumped medium: 2605N or 2205 duplex stainless steel, and Cr30 wear-resistant and anti-corrosion material especially for FGD device absorption tower.
■Material of suspension, bearing box etc. parts: gray cast iron 200.
■Mainly used as circulation pump of gypsum slurry of absorbing tower of FGD process.
■Slurry pump of ammonium phosphate
■Other applications of big flow rate and low head.
