Technical parameter range of HTL series pumps:
Flow rate: 300 ～ 14000m / h
15 ～ 30m
A 20 ～ 120 ℃
Lubrication: Thin oil lubrication
Material selection of HTL overflow parts:
The design of the desulfurization pump and the selection of the material of the overcurrent parts are the key to the FGD slurry's delivery and determine the suitability and life of the FGD device. It has both severe chloride corrosion (absorption of CI content in the slurry up to 20000-80000ppm) and solid phase Abrasion of materials (absorbed slurry contains 15% solids, concentrated slurry contains gypsum up to 50%),
The harsh media conditions place extremely high requirements on the corrosion and wear resistance of the pump.
According to the characteristics of FGD slurry transportation, we have developed materials for the flow components of both corrosive and abrasive media, and different materials can be selected for different flow components.
2605N: N-containing super duplex stainless steel developed on the basis of duplex steel Z3CNUD26.05M, equivalent to the German 1.4517 material, with excellent corrosion resistance and wear resistance.
High chromium ferritic stainless steel: cr30, Cr30A, of which Cr30A is a special material for FGD developed by our company based on the technology of foreign companies for the transport characteristics of FGD slurry, HRc43 ～ 39, used to transport PH value 4,13, and contains Pump flow parts for corrosive media with solid particles
Pump model and significance
HTL series pump model meaning example: HTL700 / 900:
HTL: Desulfurization circulating pump series code
700: pump inlet and outlet diameter (mm)
900: nominal diameter of the impeller (mm)
