摘要： 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).

摘要： A system for transferring molten metal from a vessel and into one or more of a ladle, ingot mold, launder, feed die cast machine or other structure is disclosed. The system includes at least a vessel for containing molten metal, an overflow (or dividing) wall, and a device or structure, such as a molten metal pump, for generating a stream of molten metal. The dividing wall divides the vessel into a first chamber and a second chamber, wherein part of the second chamber has a height H2. The device for generating a stream of molten metal, which is preferably a molten metal pump, is preferably positioned in the first chamber. When the device operates, it generates a stream of molten metal from the first chamber and into the second chamber. When the level of molten metal in the second chamber exceeds H2, molten metal flows out of the vessel and into another structure, such as into one or more ladles and/or one or more launders.
