Abstract

A molten metal pumping device is disclosed that comprises a pump base (50), one input port (56), a pump chamber (58) output port (11) rotor (70), rotor shaft (40), superstructure (24), motor (28), drive shaft (36) and coupling (38). The dual-flow rotor (70) extends beyond the input port (56) to deflect solid particles and direct molten metal both into the chamber and out through the discharge. The coupling is flexible and has two coupling members (100, 180) a flexible disc and a socket-like connection to the rotor shaft (40). The housing (50) includes a discharge (11) leading to an output port and a button adaptor extending from the discharge to connect metal transfer conduit (300) without the use of cement. Connection of this conduit (300) to the superstructure (24) uses an adaptor (409) to avoid the use of cement. All vertical members such as the support posts metal transfer conduit (300) and rotor shaft (40) may be sectional. A stationary component of the device may retain a thermocouple.
