Abstract
A dual chamber mixing pump is disclosed with two pump chambers. The chambers are defined in part by a piston having proximal and distal ends and recessed sections disposed at both ends. The pump utilizes one common driving mechanism to axially rotate and laterally reciprocate the piston to provide continuous pumping of two fluids entering through two inlets and exiting through two outlets with reduced pulsations. Alternating pulses of the two chambers and joining of two outlets provide a common outlet stream which has small segments of alternating fluid from each inlet. Such segmented streams can become more thoroughly mixed through normal flow characteristics of the downstream flow path, providing more effective mixing.
