A medical infusion system is described employing a pump for conducting fluid or semi-solids from an upstream portion to a downstream portion of the system. The pump includes conduit means defining, in part, a removable cassette having a window therein and a diaphragm spanning the window. The cassette has inlet and outlet openings valvelessly communicating with the pumping chamber or cavity of the cassette. Fluid in the conduit is pumped by restricting and opening the conduit means at three different locations, one of which is before the cassette and one of which is after the cassette and the third of which is at the diaphragm of the cassette.
