IHF single-stage single-suction oxygen plastic alloy chemical centrifugal pump (referred to as IHF centrifugal pump) it is designed and manufactured according to international standards and combined with the process of non-metallic pumps. The pump body is made of metal the shell is lined with polyethoxyethylene propylene glycol (F46), and the pump cover, impeller and bushing are all made of metal inserts. The outer epoxy plastic is sintered and pressed as a whole, and the shaft seal adopts the outer type of advanced bellows. Mechanical seal, 99.9% alumina ceramics (or silicon nitride) are used for the static ring, and 99.9% alumina ceramics (or silicon nitride) are used for the dynamic ring. The tetraoxygen filling material has excellent corrosion and wear resistance and sealing properties.The import and export of the pump are cast the steel body is reinforced to enhance the pressure resistance of the pump.Actual use shows that the pump is resistant to corrosion, wear resistance, high temperature resistance, non-aging, high mechanical strength, stable operation, advanced structure and combination management, strict and reliable sealing performance, easy disassembly and maintenance, long service life and other advantages.
