A flexible impeller pump includes first and second component housings. The first component housing includes a first flexible impeller and the second component housing includes a second flexible impeller. As these impellers rotate within their respective housings, they draw in and expel individual components into a common receiving chamber. In a particular application, one component is a foamable liquid, and the other component is air, and a mixture of foamable liquid and air is thus created in the common receiving chamber.
