CQB-F Full Fluorine And Fluorine Lining Magnetic Pump are made of "polyvinylidene fluoride plastic alloy (PVF₂) and ultra-high molecular weight polyethylene (UHMWPE)". At room temperature, PVF₂ has good corrosion resistance to halogens, halogenated hydrocarbons, strong oxidants, boiling acids, alkalis and other organic solvents; UHMWPE has good corrosion resistance to non-oxidizing acids (dilute sulfuric acid, nitric acid and high concentrations of hydrochloric acid, phosphoric acid, hydrofluoric acid, formic acid, acetic acid), ammonia and amines and various alkalis and salt solutions. Both materials are not resistant to strong oxidizing acid corrosion. The outer shell of the fluorine alloy pump is made of metal material, which has sufficient strength to withstand the mechanical impact of the pipeline and the outside world. The transmission power below 3kW adopts a full fluorine structure.
