IHF is the single stage single suction type fluorine plastic alloy chemical industry centrifugal pump, this pump is defers to the international standard and unifies the nonmetallic pump′s processing technological design production. The pump body uses the metal shell inside lining to gather the entire fluorine second grade propylene (F46), the pump cover, the impeller and the axle sleeve use the metal to inlay the outsourcing fluorine plastic overall agglutination suppression formation, the axis seal use four fluorine packing material, the import and export use the cast steel body reinforcement.this pump has anticorrosive, wear-resisting, thermostable, does not get older, the mechanical strength to be high, the revolution is steady, the structure advanced reasonable, the sealing property strict reliable, the disassemblage overhaul is convenient, service life long and so on merits, widely is suitable for professions and so on chemical industry, drugs manufacture, petroleum, metallurgy, smelting, electric power, galvanization, dye, agricultural chemicals, papermaking, food, spinning and weaving, under - 85℃~200℃ temperature condition long-term transportation arbitrary concentration sulfuric acid, hydrochloric acid, hydrofluoric acid, nitric acid, aqua regia, strong alkali, strong oxidant, organic solvent, reducing agent and so on strong corrosive medium, is the present world is one of most anti-corrosive equipment.
