摘要： An assembly that includes an impeller having an upper face, a lower face, and a central bore sized and shaped to mate with a connecting end of a shaft. The central bore is defined by a plurality of ledges that each include a cement groove, and channels disposed between the ledges. The connecting end includes a plurality of slots, and extended grooves disposed between the slots. Each extended groove includes an end that extends perpendicular to the length of the extended groove. In application, the plurality of ledges frictionally communicate with the outer surface of the shaft. The plurality of channels of the impeller align with the plurality of grooves of the shaft defining passages that provide a tunnel for entrainment of particles entering the impeller. The cement grooves of the impeller further align with and receive the extended grooves and ends of the shaft resulting in a stronger connection between the shaft and impeller.

摘要： A molten metal pump apparatus that includes a base member, at least two (2) support members or posts, and a post socket. The lower end of each post is mounted to a mounting bore of the base member and forms a cement-less pump joint. The upper end of the post is connected to the post socket to form a cement-less pump joint. The post socket is defined by a first half and a second half that have an open or separated position for receiving the upper end of the post and a closed or joined position for securing the upper end of the post.

摘要： A molten metal pump apparatus that includes a base member, at least two (2) support members or posts, and post sockets. The lower end of the posts are mounted to the base and forms a cement-less pump joint which is an objective of the present invention. The upper end of the post is connected to the post socket to form a cement-less pump joint which is a further object of the present invention. The connection joint between the posts and the base member and the post socket does not require cement to form or secure the joint. Therefore a replacement post identical to posts of the present invention may be provided without the need to dig out a cement joint but instead can be more easily removed and replaced.

摘要： A coupling assembly for connection between a drive shaft and an impeller in a molten metal pump. The coupling assembly includes an upper portion to receive an end of the motor drive shaft and a lower portion to receive an end of the impeller shaft. The impeller shaft is pinned to the lower portion with a pin member which extends through first and second apertures in the lower portion of the coupling body. The pin member includes a handle portion, a driver member, and a stop. The driver member has an elongated configuration sized and shaped to pass through the first aperture of the coupling member. In application, once the impeller shaft is positioned in the coupling body, the pin member is passed through the apertures such that the driver member passes through the second aperture until the stop is in abutting relationship with the coupling member outer surface. Once the pin member and therefore driver member is inserted, the driver member is a contact point between the interior of the coupling member and impeller shaft.
