Molten metal pump
First Claim
1. A connector for connecting a post assembly of an associated molten metal pump to a motor mount, the connector comprising:
- a side wall;
an internal wall extending from the side wall and including an axially aligned opening adapted to receive an elongated rod, the side wall and the internal wall defining a lower receptacle adapted to receive a barrel nut of the post assembly and an upper receptacle adapted to cooperate with a motor mount or a structure connected to the motor mount, the barrel nut including a threaded opening adapted to align with the opening of the internal wall, and a fastener having a first end configured to engage the motor mount and a second end configured to engage the threaded opening of the barrel nut.

Abstract
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 can include a cap member having a plurality of generally polygonally shaped inlet openings communicating with internal passages of the impeller, each inlet opening having an inner wall and an outer wall, the outer wall being longer than the inner wall, each inlet opening also including a leading wall and a trailing wall, the leading wall and the trailing wall each interconnecting the inner wall and the outer wall and each being inclined such that an uppermost edge of each wall precedes a lowermost edge of each wall in a first rotational direction.
