DT型臥式脫硫泵主要過流部件材質：葉輪、耐磨板Cr30A，泵體、后泵蓋2605N，或與此相同材質GLH-5、A49材質。
DT型臥式脫硫泵主要應用于濕法FGD裝置中脫硫吸收塔的循環(huán)用泵，其主要工藝為將吸收塔中的石灰石漿液與二氧化硫煙氣循環(huán)作用，排出工業(yè)石膏并消除二氧化硫氣體。其煙氣脫硫漿液介質狀況主要為：15-25Wt%石膏和碳酸鈣漿液、PH=4-7，Cl- 60000ppm， 溫度50-55℃，比重1.15. 含固腐蝕性高速流動的復雜介質對循環(huán)泵的用材提出了苛刻的要求。因此漿液循環(huán)泵過流部件的耐腐蝕耐磨蝕性能是決定該泵使用壽命的重要指標。
