A molten metal pump (10) includes a filter (30) that prevents ingestion of foreign material such as dross from molten metal within which the pump (10) is immersed. The filter (30) is a large structure that is secured to the base of the pump (10) surrounding the pump's inlet. The filter (30) forms a cavity (36) adjacent the pump's inlet. The ratio of the surface area of the filter (30) to the inlet area of the pump (10) is very large: the filter (30) has a low porosity while maintaining a high flow rate for the pump (10).
