ABSTRACT:
A device for pumping molten metal that eliminates rotor bearing members comprises a pump having a pump chamber including a first bearing surface, and a monolithic rotor having a second bearing surface that aligns with the first bearing surface. The second bearing surface is formed of and integral with the material forming the rotor. Preferably a rigid rotor shaft to motor shaft connection is utilized to rigidly center the rotor within the pump chamber and, hence, within the first bearing surface.
