PROBLEM TO BE SOLVED: To provide equipment for melting metal solids in a furnace and a method of melting the metal solids.SOLUTION: A molten metal pump includes an impeller, a pump base housing at least partially enclosing the impeller, a shaft connected to the impeller, a motor connected to the shaft, a motor mount plate for supporting the motor, and a post for connecting the motor mount plate to the pump base housing. The molten metal pump can include a connector that connects the post to the motor mount plate. The molten metal pump can include a socket for connecting the shaft to the motor. The shaft can comprise an assembly including an elongated metal rod having a first end and a second end and a metal non-circular drive member attached at the second end of the elongated metal rod. The impeller is inclined so that an uppermost edge of each wall precedes a lowermost edge of each wall in a first rotational direction. |
