Abstract
An electromagnetic pump for molten metals wherein a rotating magnetic field causes rotation of the molten metal about the axis of the pump structure. A swirl inducer at the inlet end of the pump has inlet passageways radially spaced from the axis of the pump so as to induce rotational flow in the molten metal passing therethrough. A dual-conical shaped inductor supported within and axially aligned with a molten metal passageway forms in combination with said passageway a conically tapered flow path for the molten metal. Angularly oriented flutes are provided in the region of the inductor periphery within the vicinity of the largest diameter portion thereof in order to convert the rotational flow of the molten metal back into axial flow for discharge from the pump.
