Abstract
A peristaltic pumping system comprises a flexible tube, a substantially cylindrical rotating roller unit containing a series of rollers which are freely rotating around their axes and freely moving along a radial segment, holding mechanism for commonly holding the rollers, a central spreader element for pushing the rollers against the flexible tube and a driving unit comprising a driving coupling element, and the holding mechanism is made of at least one planar element having retaining and guiding means for rollers, and the planar element is furthermore adapted to be directly coupled to the coupling element in such a way that rollers are driven through the planar element.
