Some size of rotor magnets suitable for use in magnetic drive pump

The inner rotor magnet in a water pump is one of the core components in magnetic drive pumps, brushless DC pumps, and some shielded pumps. Recently, many customers have inquired about similar magnets. Taking advantage of the current downtime, Xiao Fu has compiled a selection of magnets suitable for pump-related applications. If you are interested in any of the dimensions, please feel free to contact us.

Currently, the main permanent magnet materials used in water pumps on the market are sintered ferrite, injection-molded ferrite, and bonded NdFeB. As for sintered NdFeB, it is rarely used by customers. Regarding the number of magnetic poles, the primary types are radial 2-pole and radial 4-pole configurations.
