Low eddy-current loss efficient magnetic pump

The invention belongs to the technical field of magnetic pumps, in particular to a low eddy-current loss efficient magnetic pump. An effective nonconductive gap between outer magnetic steel and innermagnetic steel is reduced, so that the magnetic flux density of an air gap between the outer magnetic steel and inner magnetic steel of the magnetic pump is improved. The low eddy-current loss efficient magnetic pump comprises a magnetic pump body which is characterized by being composed of a pump body, a stationary ring, an impeller, a seal ring, a thrust ring, a bearing, a shaft sleeve, an impeller supporting body, an outer magnetic steel assembly, an isolating sleeve, an inner magnetic steel assembly, a fixed supporting body and a rotary supporting body. A magnetic transmission device is mounted in a magnetic transmission housing and is assembled on the outer magnetic steel assembly and the inner magnetic steel assembly by arranging an even number of permanent magnets according to a rule that poles N and S are
