Abstract
A submersible, single phase electromagnetic pumping assembly (10) for liquid metal is made, which contains a submersible pump section (16) and a nonsubmersible pump section (18) connected by a hollow conduit (20) where single phase electromagnetic windings (22 and 24) are disposed in each pump section, providing a two stage pumping assembly, and an eddy current blocking electromagnetic winding (22 and 24), providing liquid flow orifices unoccupied by the structure within each pump section near the winding, and where the single phase coils can create a pulsed, standing magnetic wave within each liquid flow orifice.
