Abstract
An apparatus for moving a stream of molten metal comprising a pumping member, a housing at least partially enclosing the pumping member, a power device seated on a support, and a shaft connecting the power device and the pumping member. At least one post is disposed between the support and the housing. The post includes an elongated rod comprising a metal alloy surrounded by an outer sheath. An inner member may surround the rod and provide a molten metal resistant barrier. The rod includes a first end connected to the support and a second end secured to the housing. A similar design for a shaft is also provided.
