The magnetic drive pump is a new type of sealless pump that uses the principle of permanent magnet transmission technology to achieve contactless transmission of torque. There is no mechanical connection between the driving shaft and the driven shaft, and no dynamic seal is required in the structure. Therefore, this type of pump has no seal and can achieve zero leakage. The magnetic drive pump is especially suitable for transporting flammable, explosive, volatile, toxic, and hazardous materials. For corrosion and precious liquids, magnetic pumps are mostly used in situations where the magnetic drive pump can only leak slightly or even without leakage, as well as in high vacuum situations where mechanical seals are difficult to handle.
