Abstract

A molten metal pumping device is disclosed that comprises a pump base including at least one input port, a pump chamber, and a discharge leading to an output port. A rotor is retained within the chamber and is connected to a rotor shaft. The device further includes a superstructure attached to and positioned above the pump housing, a motor on the superstructure, a drive shaft connected to the motor and a coupling connecting the drive shaft to the rotor shaft. The rotor extends beyond the input port to deflect solid particles thereby reducing jams and preferably is a dual-flow rotor, directing molten metal both into the chamber and out through the discharge. The coupling is flexible and has two coupling members with a flexible disc disposed therebetween. Another aspect of the invention is a housing for a transfer pump that includes a discharge leading to an output port and a button adaptor extending from the discharge. The button is dimensioned so that it can connect to a metal transfer conduit without the use of cement thereby reducing maintenance costs and downtime. Further, the vertical members such as the support posts, metal transfer conduit and rotor shaft, may be sectional so that anti-corrosive materials may be used for the sections positioned in the most corrosive areas of the molten metal furnace. Additionally, a stationary component of the device may be configured to retain a thermocouple.
