IHF type fluorine lined pump

1、 Overview of IHF fluorine lined pump:
The IHF type fluorine lined pump is designed and manufactured according to international standards and combined with non-metallic pump technology. The pump body adopts a metal shell lined with perfluoroethylene propylene (F46), and 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 an advanced external corrugated pipe mechanical seal. The static ring is made of 99.9% alumina ceramic (or silicon nitride), and the dynamic ring is filled with PTFE material, which has excellent corrosion and wear resistance 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.

2、 Selection of mechanical seals for IHF fluorine lined pumps:
The IHF type fluorine lined pump adopts the most advanced external PTFE corrugated pipe mechanical seal, which is characterized by compensating for the radial runout of the pump shaft, single end face sealing external installation, easy loading and unloading, intuitive working state, good corrosion and wear resistance sealing performance, and multi-layer protection, extending the service life of the mechanical seal; For conveying corrosive media containing impurity particles, a single end hard to hard (silicon carbide to silicon carbide) mechanical seal without cooling water can be used. For special corrosive media such as strong alkali and hydrofluoric acid, a pressureless sintered silicon carbide seal can be used; When selecting, users need to consider the solid content in the medium and the special corrosiveness of the medium
