Liquid metals are centrifugally pumped from a static container without the necessity for employing a mechanical impeller. A powerful rotating magnetic field surrounding the static container causes the metal to be rotated vigorously and the velocity head so created is converted in a volute shaped head into vertical motion to the desired delivery point.
