Patent ID: 8096530

Claim:
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, and a 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; the first component impeller and pump housing designed to move a non-compressible fluid; a second component impeller pump including: a second component housing having an inlet and an outlet for the passage of the second component, and a second component impeller received to rotate within said second component housing, the second component impeller having flexible arms 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; wherein the second component pump housing is larger than the first component housing; 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.
