Pump cassettes, infusion systems, and methods are described. An example pump cassette may include a rigid body comprising a frame portion, a base portion, a compliant membrane disposed substantially therebetween, and two opposing longitudinal edge sections. The rigid body may include a controllable fluid pathway defined in part by the compliant membrane and extending from an inlet port to an outlet port. The pump cassette may include a piston disposed at least partially within the rigid body such that movement of the piston varies a volume of a pump chamber defined within the controllable fluid pathway.
