PF (FS) the chemical industry pumps, its pump body, pump, the impeller and its the transportation medium contact components use gather the vinylidene either the enhancement polypropylene mould pressing processing or the note plastic processing become. Gathers the vinylidene plastic to have the mechanical strength high, the anti-corrosive performance is good, is on international applies one of widespread engineering plastics. PF (FS) the chemical industry pumps can satisfiedly transport under -50 ~~80 temperature condition the many kinds of densities sulfuric acid, the hydrochloric acid, the nitric acid, the acetic acid, the phosphoric acid, presses industry sector and so on the acid, oxalic acid, hydrofluoric acid and lye, organic solvent, agricultural chemicals, drugs manufacture, galvanization, environmental protection transports does not contain the pellet the corrosive medium energy conservation to pump.
