An inlet protector or guard that prevents jamming and clogging of a molten metal pump. The guard includes a flat surface having a central opening that accepts a shaft of the molten metal pump. A wall extends from the periphery of the flat surface along a longitudinal axis of the shaft. The wall is sized to fit within an inlet opening of the pump. The wall includes a plurality of openings, forming an inlet through which molten metal can enter a base of the pump. The plurality of openings are small enough to prevent solid particles that are larger than a distance between an impeller of the pump and a pump chamber from entering the pump and large enough to prevent the pump from clogging.
