The fluoroplastic lined pump is a chemical centrifugal pump that is fully lined with fluoroplastics and is corrosion resistant. The lining material is made of polyfluoroethylene propylene (FEPF46 for short). The lining of the fluoroplastic lined pump has excellent corrosion resistance, good rigidity, Impact resistance, vibration resistance and deformation resistance, has been widely used in petroleum, chemical and other industries to transport corrosive liquids and gases.
Fluorine plastic lined pump can be used under the following conditions: temperature 80~160, pressure 16 kg/cm², vacuum range (instantaneous, normal temperature) 400 mmHg. In use, it shows its unique performance.
(1) Its performance and corrosion resistance are better than phenolic clay, enamel products, glass-lined products and stainless steel. Especially when used in the presence of strong oxidants, the service life is one to several times longer than the above materials. In particular, they can withstand the penetration and corrosion of ether media
(2) Can withstand the test of various corrosive media. Among the media used in the process, there are bromine, benzene, formaldehyde, hydrochloric acid, hydrochloride, 50% sulfuric acid, 12% nAscn, HSCN, isopropyl ether, 22% Na○H, chlorobenzene water, p-benzenesulfonic acid, 99.5% chlorine, 95~90% tert-butyl hypochlorite, 0.51% free chlorine, 11~12% chloropropanol aqueous solution (PH=2~3), chloropropanol, chloroacetone BB-dichloroisopropyl ether, Dichloropropane, 100% benzene, hypochlorous acid, CC L4, etc.
(3) In the presence of various corrosive media, it can be used even at around 160C. For example, 666 chlorinated solution contains various corrosive media such as benzene (100%), hypochlorous acid, and hydrochloric acid, including strong organic solvents, strong oxidizing media, and strong acids. In addition to F46 and F4, It is difficult to find a suitable material that can resist alternating or simultaneous corrosion of these media at the same time. At present, the domestically produced perfluorinated (fluorine plastic alloy) corrosion-resistant pumps (small pumps) such as: CQB fluorine plastic drive small magnetic pump, FSB fluorine plastic centrifugal pump and other pump impellers and other accessories are made of fluorine plastic alloy (F4 It is processed by mixing with F46 and a small amount of additives in a certain proportion). Fluoroplastic alloy has incomparable corrosion resistance and mechanical strength. Impact resistance, vibration resistance, distortion resistance and non-toxic decomposition. Fluoroplastic alloy has incomparable corrosion resistance and mechanical strength. Impact resistance, vibration resistance, distortion resistance and no Toxins break down.
Fluoroplastic lined pumps and pump accessories produced with such special materials have the following advantages:
(1) Corrosion and high temperature resistance, it can transport any concentration (strong) acid, alkali, oxidant and other corrosive media without damage.
(2) High mechanical strength, small size, compact structure, convenient use and maintenance, smooth runner, high efficiency, and energy saving
