The current domestic production of fluorine plastic type corrosion pump (large pump) such as: CQB fluorine plastic lining material, driving a large magnetic pump IHF fluorine plastic centrifugal pumps, FZB fluorine plastic self-priming pump and the pipe quality are fluorine fluorinated ethylene propylene generation (FEP, referred to as F46) and F46 pump liner excellent corrosion resistance and excellent rigidity, CQB magnetic pump and power oscillation and impact resistance, resistance to distort, has been widely used in the transport of corrosive liquids and gases in petroleum and chemical industry. The wear-resistant mortar pump can be used under the following conditions: temperature -80 C ~ 160 C, pressure ≤ 16 kg / cm 2, vacuum scale (instantaneous, normal temperature) 400mmHg column. In the process of application, it shows its unique function. The examples of application and benefit are as follows: I

(1) can withstand the testing of various corrosive media. Fluorine plastic magnetic pump has been used in the process of the medium, with bromine, benzene, formaldehyde, hydrochloric acid, sulfur acid, hydrochloride, 50%, 12%NaSCN, HSCN, isopropyl ether, 22%NaOH, chlorobenzene water, benzene sulfonic acid, 99.5% chlorine of 95~90% tert butyl hypochlorite, 0.51% free chlorine, chlorine alcohol aqueous solution 11~12% (PH=2~3), chloropropanols, monochloroacetone one or two BB chloride isopropyl ether, two epichlorohydrin, 100% benzene, hypochlorous acid, CCL4 etc..

(2) in the presence of various corrosive media, it can be used even at about 160 degrees C. For example, the 666 benzene chloride solution (100%), hypochlorous acid, hydrochloric acid and other corrosive media, both strong organic solvents and strong oxidizing media, there are strong, in addition to F46, F4, fluorine plastic self-priming pump is difficult to find a suitable materials to replace these with medium resistance or with corrosion.

(3) the use of function and corrosion resistance function is superior to phenolic resin, enamel products, glass lining and stainless steel. In particular the use of strong oxidants in the presence of the occasion, the service life is one to several times the above information can improve the fluorine plastic centrifugal pump, particularly pointed out that they have suffered corrosion soaked media ether.
