Both magnetic drive pumps and shielded pumps belong to the category of sealless centrifugal pumps; they feature only static seals rather than dynamic seals, which ensures no leakage during operation. 1) Working principle: 1.1 Magnetic pump: It utilizes the property that magnets can attract ferromagnetic materials, as well as the magnetic force that exists between magnets or magnetic fields; non-ferromagnetic materials have little or no effect on the strength of this magnetic force. Therefore, power can be transmitted without contact through non-magnetic conductors. 1.2 Shielded pump: Both the pump head and the motor are enclosed within a pressure vessel filled with the medium to be pumped, and this secondary pressure vessel has only static seals. The impeller and the motor rotor are fixed to the same shaft; a shield sleeve is used to separate the motor’s rotor from its stator. The rotor rotates within the medium being transported, with power being transmitted to it through the stator’s magnetic field. This pump has no coupling. 2). . . To be continued. . .
