摘要： A molten material pump includes an impeller housed within a base member of the pump. A plurality of grooves are defined in a peripheral sidewall of the impeller for either drawing a molten material into the base member's chamber or pushing molten material out of the base member's chamber. The impeller is rotated by a rotatable shaft connected to an upper surface of the impeller. The rotatable shaft includes a non-circular shaped lower end dimensioned to be received within a cooperating opening in the impeller. The molten material pump further includes a connecting assembly for interconnecting components of the molten material pump. The connecting assembly includes a first mounting member attached to a first pump component that is dimensioned to be fitted within a cooperating recess of a second mounting member attached to a second pump component. In another embodiment of the invention, a stub shaft connects an upper shaft portion of the shaft to the impeller. The stub shaft includes a universal joint that is not rigidly connected to the upper shaft portion. In addition, the universal shaft is configured to allow the stub shaft and impeller to pivot. A floating deflector block weighs on an upper sealing block of the pump for enhancing the seal at the pump's bearing surfaces.

摘要： 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.

摘要： An apparatus for filtering molten metal held in a vessel before the metal enters the dosing tube. The filtering apparatus includes an attachment portion that mounts to the dosing tube, a filter body connected to the attachment portion and a planar surface attached to an end of the filter body opposite the attachment portion. The filter body can include a beveled end opposite the attachment portion where the planar surface is attached. The apparatus can be made from a bonded-particle material made from silicon carbide or aluminum oxide held together by an aluminum-resistant binder.
