1. A flexible impeller pump for advancing a first component and a second component to a common pathway comprising:
- a first component impeller pump including;
a first component housing having an inlet and an outlet for the passage of the first component, anda first component impeller received to rotate within said first component housing, wherein the rotation of said first component impeller draws the first component into said first component housing through said inlet and forces the first component out of said first component housing through said outlet;
a second component impeller pump including;
a second component housing having an inlet and an outlet for the passage of the second component, anda second component impeller received to rotate within said second component housing, wherein the rotation of said second component impeller draws the second component into said second component housing through said inlet and forces the second component out of said second component housing through said outlet; and
a common receiving chamber communicating with both the outlet of said first component housing and the outlet of said second component housing, such that the first and second components mix at said common receiving chamber.

Abstract
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.

11. A foam pump comprising:
-
a foamable liquid impeller pump including; a foamable liquid housing having an inlet and an outlet, said inlet communicating with a source of foamable liquid, and a foamable liquid impeller received to rotate within said foamable liquid housing, wherein the rotation of said foamable liquid impeller draws foamable liquid from said source of foamable liquid into said foamable liquid housing through said inlet and forces foamable liquid out of said foamable liquid housing through said outlet; an air impeller pump including; an air housing having an inlet and an outlet, said inlet communicating with a source of air, and an air impeller received to rotate within said air housing, wherein the rotation of said air impeller draws air into said air housing through said inlet and forces air out of said air housing through said outlet; a primary drive member keyed to said foamable liquid impeller and said air impeller, such that, when said primary drive member is driven, both said foamable liquid impeller and said air impeller are caused to rotate within their respective liquid and air housings; and a common receiving chamber communicating with both the outlet of said foamable liquid housing and the outlet of said air component housing, such that air and liquid soap mix at said common receiving chamber.
