Abstract
A system is disclosed for pumping fluids at desired average flow rates by applying a predetermined force to a pump chamber and pulsing an outlet valve of the pump chamber to deliver a fluid therefrom. In some embodiments, pump chambers are provided within removable pumping cartridges that are constructed and configured to be coupled to a reusable pump drive component. In other embodiments, the pumping cartridges include multiple pump chambers, which pump chambers are operated so that a pump flow rate of one pump chamber is a predetermined fraction of the pump flow rate of another pump chamber within the pumping cartridge.
