Magnetic pump has been widely used in the transportation of various liquid chemicals. As a manufacturer, what kind of structure and configuration to produce magnetic pump products, different structural forms and configuration, will bring different effects to customers.
11th International exhibition of vacuum technologies12 – 14 April 2016 .Russia, Moscow, Sokolniki ECC, Pavilion 2.
The first aspect is the pump structure form. As a magnetic pump product for transporting chemical media, the reliability, safety and service life of the pump should be considered first in product design. These main factors involve whether a pump can be maintained for a long time without maintenance and less maintenance, as well as the user's consumption costs, spare parts costs and the invisible environment, safety issues. Therefore, it is necessary to design and manufacture a magnetic pump, which can ensure the stability of the size of each component under different temperatures, pressures and load conditions, so as to achieve long-term operation of the pump trouble-free, this is a product designer should have the idea and concept. It is not advisable to reduce the weight and quality of the product, reduce the cost of the product, and deliver the low cost, low price magnetic pump to the user.

The second aspect is the configuration of pump friction parts, as magnetic pump products, pump vulnerable parts are often in the liquid rotating friction parts, sliding bearings, thrust bearings, sleeves. The wear resistance of these parts will directly affect the service life of the pump and the cost of replacing the parts.The reason of low speed of vacuum pump
The world's famous magnetic pump manufacturers, regardless of metal or plastic magnetic pump, sliding bearings, thrust bearings, sleeves are all made of silicon carbide with excellent corrosion resistance and wear resistance. However, the bending strength of silicon carbide is only 451Mpa, the material is brittle, and the impact resistance is poor. Therefore, tungsten carbide with 1471 Mpa bending strength and more than three times the impact resistance of silicon carbide can be selected as the corrosion conditions permit. Tungsten carbide compared with silicon carbide has good toughness and good impact resistance. If the pump dry grinding, unlike silicon carbide material will be broken, resulting in internal magnetic steel and isolation sleeve parts of the rubbing, resulting in damage to the pump. Wearable parts of magnetic pump using silicon carbide, tungsten carbide material is a high configuration, can make the pump run for a long time without maintenance. The service life is much longer than that of tetrafluorographite, graphite, alumina and silicon nitride. It can reduce the cost of replacing the vulnerable parts and other parts frequently in a short time, and the cost of environment and safety because of the non-wear resistance and poor strength of the vulnerable parts.2015 The 16th China International Pu?mp, Valve Fair
