IHF Chemical Pump

1 Overview:
The IHF fluorine-lined pump is designed according to national standards, and is suitable for long-term transportation of various acids, alkalis, oxidants and other corrosive media at any concentration under the temperature of -20ºC~120ºC; the pump body is made of metal shell lined with fluorine plastic ( F46), the impeller and pump cover and other over-current components are all made of metal inserts and covered with fluoroplastic alloys for one-time high temperature molding. The IHF fluorine-lined pump combines the advantages of a variety of chemical pumps. Because the pump body is made of metal shell and lined with fluorine plastic, the mechanical strength and pressure resistance of the pump body are obviously enhanced. Replacement of parts, no need to disassemble the inlet and outlet pipes of the pump. The actual use shows that the pump has the advantages of corrosion resistance, wear resistance, high mechanical strength, stable operation, advanced and reasonable structure, reliable sealing performance, convenient disassembly and maintenance, and long service life. The product series has a total of more than 30 specifications, with a wide range of flow and head, and is well received by the majority of users. 
 
2. The choice of mechanical seal:
The IHF fluorine-lined pump adopts the most advanced externally mounted PTFE bellows mechanical seal, which is characterized by compensating for the radial runout of the pump shaft, single-end seal externally mounted, easy to install and remove, intuitive working state, and good corrosion resistance and wear resistance. , has multi-layer protection, prolongs the service life of the mechanical seal; when transporting corrosive media containing impurity particles, it can be equipped with a single-end hard-to-hard (silicon carbide to silicon carbide) mechanical seal without cooling water, strong alkali and hydrofluoric acid Pressureless sintered silicon carbide seals are used for other special corrosive media; the solid content in the medium and the special corrosiveness of the medium should be considered when selecting models.

3. Purpose:
The corrosion resistance and wear resistance of IHF fluorine-lined pumps have been confirmed by practical use and unanimously recognized by the majority of users. At present, they have been widely used in: transportation of corrosive media in chemical production, and treatment of chlorinated water wastewater in ionic membrane caustic soda projects. And acid addition process, electrolyte transportation in non-ferrous metal smelting, pickling process in automobile manufacturing, and pharmaceutical, petroleum, electroplating, dyes, pesticides, paper, food and other industries, long-term under the temperature conditions of -20 ºC ~ 120 ºC It can transport strong corrosive media such as sulfuric acid, hydrochloric acid, hydrofluoric acid, nitric acid, aqua regia, strong alkali, strong oxidant, etc. of any concentration without damage. It is one of the most popular pump equipment used by customers.
