A device for pumping molten metal that eliminates rotor bearing members comprises a pump having a pump chamber (26) including a first bearing surface (62A), and a monolithic rotor (100) having a second bearing surface (200) that aligns with the first bearing surface (62A). The second bearing surface (200) is formed of and integral with the material forming the rotor (100). Preferably a rigid rotor shaft (38) to motor shaft (70) connection is utilized to rigidly center the rotor within the pump chamber and, hence, within the first bearing surface (62A).
