Magnetic pump

Abstract

Disclosed is a magnetic pump such that it is possible to wirelessly monitor and control the operating state of a pump from a location separated from the pump. Specifically disclosed is a magnetic pump provided with a pump main body equipped with a pump case having an inlet and an outlet, and an impeller stored within the pump case in a rotatable manner and linked to a magnetic means, a rotating magnetic field generating means separated from the pump main body and for imparting a rotating magnetic field to the magnetic means; and a means for detecting the potential difference between the rotating magnetic field and the magnetic field produced by the magnetic means and imparted outward.
