Abstract
Provided is a magnetic pump that includes an isolation hood, an electric motor, a first rotating magnet, a second rotating magnet, and a pump body. The isolation hood includes a first mounting position and a second mounting position which are isolated and sealed from each other. The electric motor and the second rotating magnet are both disposed on the first mounting position, while the first rotating magnet and the pump body are both disposed on the second mounting position. Further provided is a water pumping device that includes a magnetic pump and a box filled with a liquid to be transported. The magnetic pump is arranged on the box, the magnetic pump being the magnetic pump described above. Further provided is a method for using a magnetic pump, which can prevent contact between a power cable of the electric motor and the liquid inside the box.
