Safety Industrial Canned Motor Pump / Canned Motor Centrifugal Pump High Efficiency

Principles and structural characteristics of canned pumps

Ordinary centrifugal pumps are driven by connecting the impeller shaft of the pump to the electric shaft through a coupling, so that the impeller and the motor rotate together to work, while the canned pump is a sealless pump, and the pump and the drive motor are sealed in a A pressure vessel filled with pumped medium has only a static seal, and a wire set provides a rotating magnetic field and drives the rotor. This structure eliminates the rotating shaft sealing device of traditional centrifugal pumps, so it can be completely leak-free.

The shield pump connects the pump and the motor together. The motor's rotor and the pump's impeller are fixed on the same shaft. The shield sleeve is used to separate the motor's rotor and stator. The rotor runs in the transported medium, and its power passes through the stator's magnetic field. passed to the rotor.

In addition, the manufacturing of the canned pump is not complicated, and its liquid end can be designed and manufactured according to the structural type commonly used by centrifugal pumps and relevant standard specifications.
