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.
