Abstract
This disclosure features a transfer pump for pumping molten metal having a riser with a reusable socket. The pump includes a motor, support structure above a molten metal bath, a motor driven shaft and an impeller on an end of the shaft rotatable in a base. A riser made of refractory material extends from a transfer opening in the base to the support structure. The riser has a passageway for molten metal along a length of the riser. A clamp has a first clamp portion fixedly connected to the support structure and a second clamp portion that is pivotable with respect to the first clamp portion. A fastener is used to open and close the clamp. Sections of a split socket each have a flange and a body portion. The socket is received in the clamp such that the flanges of the socket are disposed above the clamp, and when the clamp is closed the socket holds the riser.
