Under normal temp., PVF2 has a fine corrosion resistance to many organic solvents like halogen, halogenated hydrocarbon, strong oxidant, boiling acid and alkali; UHMWPE has a fine corrosion resistance to inoxidable acid （dilute sulfuric acid, nitric acid and large concen-tration hydrochloric acid, phosphorus acid, hydrofluoric acid, formic acid and acetic acid）, ammonia, amine and various alkali and salty solutions. Both materials can‘t resist the corrosion of strong oxidable acid. The fluorine alloy pump has a metal shell with enough tenacity to afford the mechanical impact from the pipeline and outside. Those with transmission power below 3KW adopt full fluorine structure.
