ALL flow-through parts of CQB-F fluorine lining magnetic pump are made of PVF2 and UHMWPE. 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 concentration hydrochloric acid, phosphorus acid, hydrofluoric acid, and salty solutions. Both materials can¡¯t resist the corrosion of strong oxidable acid. The fluorine alloy pump has a metal shell pipeline and outside. Those with transmission power below 3kw adopt full fluorine structure.
