Molten metal transfer pump
First Claim
1. A molten metal pump for transferring molten metal from a first vessel to a second vessel, the pump comprising a base member including a pumping chamber, a motor supported on a platform by at least one post, a rotatable shaft secured at a first end to said motor and at a second end to an impeller disposed within said pumping chamber, the pumping chamber including an outlet to a first end of an elongated refractory tube having a longitudinal axis substantially parallel to said shaft, said tube having a second end passing through an opening in said platform, said tube including a metallic cladding attached to an outer wall adjacent said second end, a releasable fastening member engaging said metallic cladding and securing said tube to said platform, said metallic cladding forming a portion of a connection to a piping assembly, and said tube being selectively vertically adjustable within said fastening member.

Abstract
A molten metal pump for transferring molten metal from a first vessel to a second vessel. The pump is constructed of a base member including a pumping chamber, a motor supported by at least one post, a rotatable shaft secured at a first end to said motor and at a second end to an impeller disposed within said pumping chamber. The pumping chamber includes an outlet to a first end of an elongated refractory tube having a longitudinal axis substantially parallel to the shaft. The tube has a second end passing through an opening in the platform. The tube includes a metallic cladding attached to an outer wall adjacent it'"'"'s second end. A releasable fastening member is used to secure to the portion of the tube having the metallic cladding to the platform.
