Abstract
A system and method for pumping fluid using a set of interconnected pump cassettes is disclosed. Each of the pump cassettes can receive a first solution in a first pumping chamber and each of the pump cassettes can receive separate second solutions in respective second pumping chambers, so that the first solution can be mixed with the separate second solutions, each said mixture capable of being placed in separate containers. The system includes a control assembly for operating each pump cassette, each pump cassette having a flexible membrane to pump fluid into and out of the pumping chambers, and each pump cassette configured for mating with a base unit that provides positive or negative pneumatic pressure to the flexible membrane.
