The half deficient liquid centrifugal pump in a decarbonizing system suffered from serious corrosion and did not work normally after operating only for about one year.

According to the function and principle of pump, the tries to solve the leakage problem of common chemical centrifugal pump under the strong corrosion and abrasion are sought.

Fluorine plastic is one of the world's most outstanding corrosion resistant materials, American Standard VTP type selection of the materials for the production of fluorine pipeline pump.
