As an advanced fluid conveying equipment, magnet driven pump has been widely used in many fields such as chemical industry, pharmaceutical industry, food industry, etc. with its unique magnetic transmission technology and leak-free design. Among them, corrosion resistance is a highlight of magnet driven pump and the key to its efficient and stable operation in corrosive medium transportation.
The corrosion resistance of magnet driven pump is mainly achieved through the following aspects:
First, the key components of magnet driven pump, such as pump casing, impeller, isolation sleeve, etc., are usually made of materials with excellent corrosion resistance. These materials include stainless steel, ceramics and fluoroplastics (such as PTFE, FEP, PFA), which have extremely high resistance to corrosive media such as acids and alkalis. For example, fluoroplastics are one of the best corrosion-resistant materials in the world today, and can maintain stable performance for corrosive media such as acids, alkalis, oxidants, etc. of any concentration (strength).
Secondly, the design of magnet driven pump also fully considers the need for corrosion resistance. Its internal structure is reasonably designed to avoid dead corners and liquid accumulation areas, reduce liquid retention, and thus reduce the possibility of corrosion. At the same time, the surface of the pump body is specially treated, such as polishing, nitriding or electroplating, to further improve its corrosion resistance and reduce the adhesion of dirt and corrosive substances.
In addition, the magnet driven pump also transmits power through a magnetic coupler to achieve contactless transmission between the pump body and the motor. This design avoids the leakage problem caused by contact with corrosive media in traditional mechanical seal pumps, and fundamentally solves the hidden danger of leakage caused by wear or corrosion of seals. The liquid sealing part of the magnet driven pump is usually made of corrosion-resistant fluororubber or polytetrafluoroethylene, which further enhances its corrosion resistance.
Finally, the magnet driven pump needs to be maintained and inspected regularly during use. By checking the status of seals and other vulnerable parts and replacing worn or damaged parts in time, it can ensure that it maintains excellent corrosion resistance for a long time. At the same time, reasonable control of the temperature and pH of the pumping medium is also an important measure to maintain the corrosion resistance of the magnet driven pump.
In summary, the corrosion resistance of the magnet driven pump is achieved through the selection of corrosion-resistant materials, optimized design, contactless transmission and regular maintenance. These measures enable the magnet driven pump to maintain efficient and stable operation in the transportation of corrosive media, providing strong support for the company's production.
