Air cooled molten metal pump frame

A molten metal pump frame comprising:

• a) a base frame;
• and
• b) a molten metal pump supporting structure integrally attached to said base frame for supporting a molten metal pump, wherein said base frame and said molten metal pump supporting structure are sized to form a portable molten metal pump frame to facilitate positioning over a molten metal bath;
• c) said base frame further comprising:
• i) a first passageway therethrough;
• ii) a cooling fluid inlet for receiving a source of forced cooling fluid, said inlet being in communication with said first passageway;
• iii) means for connecting a source of electrical power to said molten metal pump;
• iv) a first cooling fluid outlet to provide flow of cooling fluid to components of said molten metal pump, said first cooling fluid outlet being in communication with said first passageway;
• d) said molten metal pump supporting structure further comprising a second passageway and a second cooling fluid outlet in communication with said second passageway to facilitate flow of cooling fluid through said molten metal pump frame, said second passageway being in communication with said first passageway.
