Selection and advantages of micro magnetic gear pump materials

Micro magnetic gear pump is a kind of precision conveying equipment widely used in chemical, pharmaceutical, food processing and other fields. Its unique leak-free design and high efficiency make it perform well in various harsh environments. This article will explore the material selection and advantages of micro magnetic gear pump.

Material selection
1. Pump body material
• Stainless steel: a commonly used pump body material with excellent corrosion resistance and mechanical strength, suitable for conveying corrosive liquids.
• Aluminum alloy: light weight, good thermal conductivity, suitable for conveying low viscosity liquids, but poor corrosion resistance.
• Engineering plastics: such as polyvinylidene fluoride (PVDF) and polytetrafluoroethylene (PTFE), with good chemical resistance and high temperature resistance, suitable for conveying corrosive liquids such as strong acids and alkalis.

2.Gear material
• Stainless steel gears: wear-resistant, suitable for high pressure and high temperature environments.
• Engineering plastic gears: such as polyetheretherketone (PEEK), with good wear resistance and chemical resistance, suitable for conveying liquids containing particles.

3. Magnetic materials
• Neodymium iron boron (NdFeB) magnets: have high magnetic energy product and high coercive force, suitable for high-performance magnetic gear pumps.
• Samarium cobalt (SmCo) magnets: have excellent high temperature resistance and corrosion resistance, suitable for high temperature environments.

Advantages
1. Leak-free design
The micro magnetic gear pump transmits torque through magnetic coupling, without the need for mechanical seals, fundamentally eliminating the risk of leakage, and is particularly suitable for conveying toxic, harmful or flammable and explosive liquids.
2. High efficiency
Due to the compact structure and high transmission efficiency of the magnetic gear pump, it can effectively reduce energy loss and improve conveying efficiency.
3. Corrosion resistance
The magnetic gear pump made of corrosion-resistant materials can operate stably for a long time in corrosive media, extending the service life of the equipment.
4. Low maintenance cost
Due to the absence of mechanical seals and bearings, the maintenance requirements of the magnetic gear pump are low, reducing downtime and maintenance costs.
5. Wide range of applications
Magnetic gear pumps are suitable for conveying liquids of various viscosities, including high-viscosity liquids and liquids containing particles, and have a wide range of applications.

The selection of materials for micro magnetic gear pumps needs to comprehensively consider factors such as corrosion resistance, mechanical strength and working environment. Its advantages such as leak-free design, high efficiency and low maintenance cost make it widely used in various industries. In the future, with the advancement of material science and manufacturing technology, micro magnetic gear pumps will have broader development prospects.
