<p>The multi-chamber liquid pump (10) of the present invention includes an input chamber (14), an intermediate chamber (22) and a liquid output chamber (18). Pressurized gas (60) provides the motive force for outputting liquid from the pump (10), such that liquid is output at a constant flow rate during pump operation. Liquid flows into the input chamber (14), through one or more valves (52) into the intermediate chamber (22), and through one or more subsequent valves (78) to the output chamber (18) while liquid is constantly output from the output chamber (18). The system controller provides control signals to the valves to facilitate the pump's continual operation.</p> |
