Pump cassettes, wound-treatment apparatuses and methods. In some embodiments, a pump cassette comprises: a pump body having a pump chamber, an inlet valve in fluid communication with the pump chamber, and an outlet valve in fluid communication with the pump chamber; a diaphragm coupled to the pump body such that the diaphragm is movable to vary a volume in the pump chamber; and an identifier configured to store one or more properties of the pump cassette such that the identifier is readable by an automated reader to determine the one or more properties. In some embodiments, the pump cassette is configured to be removably coupled to a wound-treatment apparatus having an actuator such that the actuator can be activated to move the diaphragm.
