| 摘要 |
The invention relates to a magnetic coupling pump which has an internal rotor (2) and an external rotor (3) which each carry magnet arrangements (4, 6) having magnets (7) which are arranged with alternating poles, wherein a split pot (8) is arranged between the magnet arrangements (4, 6), said split pot having a flange (9), which flange (9) can be fixed to a coupling component, preferably to a housing cover (6), by way of a mating flange. In order to avoid eddy current losses or magnetic power losses due to induction, in particular in the case of metal split pots, the invention proposes incorporating axial magnetic fields at the free narrow end faces (11) of the magnet arrangements (4, 6) by a magnetic short-circuiting element (19), which is designed in the form of a ring, being arranged at at least one free narrow end face (11). |
