Disclosed are embodiments of systems, apparatus, and methods for delivering a fluid. In one illustrative embodiment, a fluid delivery device includes a master piston coupled with at least one slave piston to move in unison with the master piston. A fluid power source, such as an electroosmotic plump, is also provided, which is configured to drive the master piston. The various pistons may be sized differently to provide for delivery rates that vary in proportion to the size difference between the pistons. In some embodiments, the fluid delivery device may provide both a driving force and a suction force such that a first fluid can be delivered out of a chamber while a second fluid is delivered into that chamber or a separate chamber.
