Use

This pump is a single-stage single-suction anticorrosive centrifugal pump sucking from axial direction. The pump body liner, pump cover liner, piper liner and bearing bush are all produced from fluon by one-time mould pressing, sintering method. The pump axis is made from 3Cr13 stainless steel and fluon spindle sleeve outside.
Fluon is one of the excellent anticorrosion material. It has very low coefficient of friction, high self-lubricity and inadhesion, can be used during the temperature range of -195-250 for long time. It can be used in acid, alkali and salt solution, strong oxidizer, organic solvents and other media(besides high-temperature molten alkali metals, element fluorine and chlorine trifluoride). This pump can be used to transport liquid in the industries of chemical, petroleum, metallurgy, pharmacy, paper making, dyeing and printing, war industry, environmental protection, seawater desalination, etc. Its anticorrosive property is highly better than other pumps made from stainless steel and non-metal materials such as glass, ceramic, graphite, silicon iron, other fluoro plastic, glass fibre reinforced plastic and F₄₆, etc.

Characteristics of IHF₄ type

1.	All sections contacting with liquid are all lined with fluon(PTFE, or F4), basically, the thickness is at least of 15mm, and the thickest is up to 35mm. The thickness of metal crust is 10-15mm. It has higher strength than domestic any other fluoro plastic pump and its run is safe and reliable.
2.	The pump is designed according to the international standard ISO2858-75, 3661-77, 3069-74 and ISO/DIS5199(equivalent to GB5662-85, GB5660-85, 5661-85, 5656-85).
3.	All the parts are high in mechanical strength , good in precision.
4	The working efficiency of pump is high. And it saves recourses.
5.	Shaft seal is stable and reliable.
	Assistance impeller, at the back of impeller with over lift of 50 meters, can reduce the pressure of mechanical seal cover and improve the reliability of mechanical seal.
6.	Convenient to be checked and mended.
