Assignee:

Metaullics Systems Co., L.P. - Solon OH

International Classification:

F04B 3500

US Classification:

417360

Abstract:

A post for a molten metal pump having an end joined to a hole in a pump base. The post end includes a longitudinal bore opening at the end of the post and a port opening to the side of the post intersecting the bore. A plug is inserted into the bore above the level of the port yet leaving a portion of the upper bore open. Cement can be injected into the bore and out the ports. Thereafter, a second plug can be inserted into the bore to drive cement out. To remove the post, it is cut across its longitudinal axis to expose the open upper portion of the bore. The opening is a pilot hole to drill a longitudinal hole in the post. A device having two members connected by a rod are attached to the upper and lower surfaces of the remaining post, respectively and tightened to break the cement joint.
