A peristaltic pump comprising a rotor and a plurality of removable cartridges associated with the rotor, wherein the occlusion beds of the cartridges are configured to enable the outflow characteristics of the pump to be varied by manipulation or interchanging of the cartridges, such that the pump may, in one mode of operation, have synchronous flow to all of its parallel flow channels, or may in a second mode of operation, have non-synchronous phase-offset flow to respective ones of the parallel flow channels. In the second mode of operation, manifolding of the output flow from respective ones of the parallel flow channels can be employed to provide flow of substantially reduced pulsation. Each of the cartridges preferably comprises a cartridge frame and a separate occlusion bed supported on the cartridge frame. In the second mode of operation, the occlusion beds of the cartridges preferably have regions of maximum occlusion offset relative to one another.
