Special materials used in magnetic drive pump

Magnetic drive pump is a new type of sealless pump which uses the principle of permanent magnet transmission technology to realize the contactless transmission of torque. In recent years, the pump has been widely used in petroleum, chemical industry, electroplating, pharmaceutical, food, paper selection, printing and dyeing and other industries abroad. In recent years, with the rapid development of magnetic drive pumps at home and abroad, according to the special characteristics of the media conveyed by the pump, and combined with the pump to withstand the mechanics of the special characteristics of the pump material updates, in the pump design using many new characteristics of the material, today we will talk about these special materials used in magnetic drive pumps.

2. Magnetic drive pump casing overflow part, the inner magnet encapsulation material

Magnetic drive pump isolation sleeve material

The use of fluorine plastic isolation sleeve in the smaller power magnetic drive pump has been commonly used, from the use of the effect in low temperature and low pressure is more ideal. The main fluorine plastics used are polytetrafluoroethylene, partial trifluoro, partial difluoro, and other materials.

A Fluorine plastic isolation sleeve made of fiber-reinforced fluorine plastic can also use thin-walled metal cylinder or metal mesh parts to strengthen the characteristics of this fluorine plastic isolation sleeve, both to reduce the generation of eddy current loss, but also to improve the compressive strength of the pump.

Magnetic drive pump casing overflow part, the inner magnet encapsulation material

The pump casing overflow part, inner magnet seal, and other parts are made of fluoroplastic material with heat resistance, strong corrosion-resistance, and good mechanical properties, which has been widely tried and tested, especially in the strong corrosive materials have excellent heat resistance, corrosion resistance, and other properties, especially F3, F2 materials, compared with PTFE, the relative density is similar (for 2.07 ~ 2.08) hardness, friction coefficient. Relative to steel is 0.3. Heat resistance and high-temperature corrosion resistance are slightly worse than F4 but have good heat resistance flow (creep), high compression strength, good wear resistance, and dimensional stability. Repeated bending, does not affect the performance, known as the fluoroplastics in the "nylon". With the corrosion-resistant lining of the pump, the bonding strength is high and the effect is good. Fluoroplastic is one of the modern engineering materials, and it has become an indispensable material in the industrial sector abroad because of its superior performance that various metals do not have.

Taicang Magnetic Pump Co., Ltd. was born in 1979. It cooperated with Shanghai Chemical Design Institute to form a unique core research project with magnetic drive pump, and achieved great success. It has become the first company in China to comprehensively design and produce magnetic drive pump. Today, Taicang magnetic pump Co., Ltd. has become a leading manufacturer of magnetic drive pumps in China, with many patents and 12 utility model patents.
