1、 Overview
The IHF single-stage single suction fluoroplastic alloy chemical centrifugal pump (referred to as IHF centrifugal pump, also known as fluorine lined centrifugal pump due to the inner lining fluoroplastic process used in the pump casing) is designed and manufactured according to international standards and combined with non-metallic pump processes. The external PTFE corrugated tube mechanical seal used for the dynamic seal has multiple layers of protection, which extends the service life of the mechanical seal. For conveying 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. Therefore, when selecting, users need to consider the solid content in the medium. Actual use shows that the pump has the advantages of corrosion resistance, wear resistance, high temperature resistance, anti-aging, high mechanical strength, smooth operation, reasonable structure, strict and reliable sealing performance, easy disassembly and maintenance, and long service life.
The IHF fluorine lined centrifugal pump produced by our company has absorbed the advanced technology, materials, and processes of fluoroplastic centrifugal pump production at home and abroad, successfully solving the technical problems of easily damaged components such as pump covers, impellers, and mechanical seals of fluoroplastic centrifugal pumps in China, making their performance more perfect. The IHF series centrifugal pumps have undergone long-term production and continuous operation tests, and more and more users are confident that they have chosen a safe and reliable pump type. We will continue to provide higher quality services to our customers.
2、 Purpose:
IHF fluorine lined centrifugal pumps are widely used in the transportation of corrosive media in chemical production, chlorine water, wastewater treatment, and acid addition processes in ion membrane caustic soda projects (most of the pumps used in ion membrane caustic soda projects in China currently use our company's products), electrolyte transportation in non-ferrous metal smelting, acid washing processes in automobile manufacturing and thin plate and strip steel production lines, as well as in many industries such as pharmaceuticals, petroleum, power, electroplating, dyes, pesticides, papermaking, food, textiles, etc. They can transport strong corrosive media such as sulfuric acid, hydrochloric acid, hydrofluoric acid, nitric acid, aqua regia, strong alkali, strong oxidant, organic solvent, reducing agent, etc. of any concentration for a long time without damage. Applicable temperature:- 20 ℃ to 100 ℃.
3、 Design Features

This series of products is designed and manufactured according to international standards (ISO2858). The pump body is made of a metal shell lined with fluoroplastic, and the impeller and pump cover are made of metal inserts wrapped in fluoroplastic alloy molded, which gives them super strong impact resistance and excellent corrosion resistance. The shaft seal uses an external corrugated pipe mechanical seal, and the wear-resistant sealing surface is available in silicon carbide, ceramic, PTFE, and hard alloy. It has a high cost performance ratio and is currently widely used as an anti-corrosion centrifugal pump in the chemical industry.
