US Classification:

417500, 417 53, 417492, 417521

Abstract:

A pair of dual chamber mixing pumps are combined which allow for a constant dispense rate profile using motor speed modulation. Each pump is divided into two chambers, the proximal chamber and the distal chamber. The chambers are defined in part by a piston having proximal and distal ends and recessed sections. The pump utilizes one common driving mechanism to axially rotate and laterally reciprocate the piston to provide continuous pumping of fluids with reduced pulsations. Each fluid enters through its own pump inlet and outlet. The pumps are operated 90 out of phase with respect to each other.
