MULTI-PURPOSE PUMP SYSTEM FOR A METAL FURNACE AND RELATED METHODS
A pump system for a metal furnace includes a tank and a magnetic stirrer. The tank includes a tank chamber that is configured to receive a fluid, such as a molten material. The tank is positioned above magnetic stirrer and such that the magnetic stirrer is outside of the tank chamber. The magnetic stirrer includes a rotating permanent magnet configured to generate a moving magnetic field in the molten material in the tank chamber that induces movement in the molten material.
