general outline Describe:
IHFFluorine lined plastic alloy centrifugal pump (abbreviated as)IHFFluorine lined centrifugal pumps are designed and manufactured according to international standards and combined with non-metallic pump processes. The pump body adopts a metal shell lined with perfluoroalkoxy（F46）The pump cover, impeller, and shaft sleeve are all made of metal inserts wrapped in fluoroplastic and sintered as a whole. The shaft seal adopts advanced external corrugated pipe mechanical seal, and the static ring is selected99.9%Aluminum oxide ceramic (or silicon nitride), with PTFE filling material for the moving ring, has excellent corrosion resistance, wear resistance, and sealing performance. The inlet and outlet of the pump are reinforced with cast steel bodies to enhance the pressure resistance of the pump. Actual use shows that the pump has the advantages of corrosion resistance, wear resistance, high temperature resistance, anti-aging, high mechanical strength, smooth operation, advanced and reasonable structure, strict and reliable sealing performance, easy disassembly and maintenance, and long service life. Applicable temperature:-20℃~100℃When the usage temperature exceeds120℃At that time, the pump impeller needs to be made of high-temperature resistant materials. Suitable for continuous transportation of high-risk liquid chemical media such as strong acids, strong bases, organic solvents, and strong oxidants of any concentration, when conveying solid particle content5%When dealing with corrosive liquid media on both sides, it is necessary to provide corrosion-resistant and wear-resistant mechanical seals.

Purpose:
Fluorine lined centrifugal pumps are widely used in acid pickling and painting processes in automotive manufacturing; Electrolyte transportation in non-ferrous metal smelting; The process flow of chlorine water, wastewater treatment, and acid addition in the ion exchange membrane caustic soda project.

Design features:
IHFThe fluorine lined centrifugal pump is designed according to international standards. 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 compression molding. The shaft seal adopts advanced external corrugated pipe mechanical seal, and the static ring is selected99.9%Aluminum oxide ceramic, with PTFE filling material for the moving ring (or other materials specially matched according to special working conditions), is characterized by good corrosion resistance, wear resistance, and sealing performance.

Temperature：-20℃~100℃

Note:1、*For standard specifications;Try to choose parameters that are the same or similar to those in this table. If they are not within the scope of this table, our factory will improve the impeller to achieve this.
2When the flow rate at the operating point is too low, a reflux pipe should be connected to the outlet.
