The invention is a compressible tube fluid flow device useful as a peristaltic pump or a motor. A first embodiment includes an outer cylinder, having a first end, a second end and a side wall, and at least one compressible tube arranged helically therein. Each tube includes a flow entrance portion associated with the first end and a flow exit portion associated with the secondend such that the fluid passes through at least one of the ends, preferably generally axially, and not through the side wall. A second embodiment has a multiple of compressible tubes arranged circumferentially within the outer cylinder. Each tube has a first and second end connected to a flow entrance and exit portion respectively, preferably aligned such that the fluid is directed generally axially. Both embodiments include means for compressing the tube and a rotatable shaft drivingly connected thereto.
