Electromagnetic pump cooling bypass

摘要

An electromagnetic pumping assembly (10) for liquid metal is made, which contains an immersible pump section (16) where electromagnetic windings (22) are disposed in the pump section, and an eddy current blocking structure (25) is disposed within the electromagnetic winding (22), providing liquid flow orifices unoccupied by the structure between the eddy current blocking structure and the winding, where there is at least one axial bore (27) through the eddy current blocking structure (25).
