CA 2242174

A system and device for pumping molten metal that reduces bearing member fractures comprises a pump having a pump chamber including a first bearing surface, a rotor having a second bearing surface that aligns with the first bearing surface. The second bearing surface is formed by a plurality of spaced bearing pins attached to the rotor. Each bearing pin has an outer surface preferably substantially flush with the outer perimeter of the rotor. The pins are comprised of a heat resistent material that is harder than the material comprising the rotor.
