In order to be used as a pump for discharging the liquid of the device, miniaturization is required, but the pump has a T-shape and a configuration in which an impeller is separately coupled from the electric drive, which makes it difficult to miniaturize it.

The present invention has been made to solve the above problems, an object of the present invention is to sequentially arrange the impeller consisting of a rotary blade inside the circular frame arranged around the magnetic material on the same axis between the inlet and outlet of the liquid It is configured to provide a pump capable of miniaturizing the structure by configuring the impeller to directly discharge the liquid while being rotated by the magnetism of the electromagnet provided around the cylindrical case.

In addition, the present invention is to provide a pump to facilitate the inflow and discharge of the liquid by arranging the auxiliary impeller before and after each of the impeller integrally formed inside the cylindrical frame having a magnetic body of the rotary wing.

In addition, another object of the present invention is to provide a pump that facilitates the replacement and cleaning of parts as well as providing convenience of handling and management through a miniaturized pump.
