China Made Horizontal Desulfurization, Desulphurization Slurry Circulation Pump

China Made Horizontal Desulfurization, Desulphurization Slurry Circulation Pump

Biref introduction:
ZTD flue fuel desulfurization pump was elaborately made to satisfy the needs of moist approach FGD of limestone(lime) and gypsum for coal fired energy plants.The hydraulic models of ZTD desulfurization pump is optimized created by CFD,and its passage is made below the principle of abrasion of slurry pump.The wetted elements material for ZTD desulfurization pump is an anti-abrasive and anti-corrosive substance which was designed by HangCZPT Pump alone. The biggest diameter of ZTD collection is 900 mm at existing, and it is extensively utilised in the flue gas desulfurization and denitration procedure of power plant and other setting defense initiatives. 


  1. Flow rate:Q=700~14000 (m³/h)
  2. Total head:H=fifteen~63 (m)
  3. Speed:n=420~980rpm
  4. S.g.:γ ≤1.5 
  5. Temperature:T=~120ºC 
  6. Pump diameter:300~900mm


  1. Elaborately designed based on the characters of flue gas desulfurization of thermal power plant to meet the requirements of a facility below 1000 MW.
  2. CZPT models are CFD optimized to have excellent performance of anti-cavitation.
  3. CZPTly designed mechanical seal for flue gas desulfurization process. 
  4. The impeller position can be adjusted by the bearing housing,this brings a shortcut to recover the pump performance under a slightly abrasion.
  5. Axial adjusting structure to maintain the distance between impeller and front cover plate to keep a high efficient operation.
  6. 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.


  1. All metal materials for pump set,without any lining rubber or other high polymer material.
  2. 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.
  3. CZPT and back open structure,the rotary part can be removed from the casing without dismantling the pipelines.
  4. Cartridge mechanical seal with internal or external flushing plans.
  5. The bearing part is back pull structure,which is assembled in the bearing housing.
  6. Transmission: directly coupled and gear box drive.

  1. Mainly used as circulation pump of gypsum slurry of absorbing tower of FGD process.
  2. Slurry pump of ammonium phosphate
  3. Other applications of big flow rate and low head.
