A pump rotor for a roller pump, is disclosed. The rotor comprises: a first roller support comprising a first roller; a second roller support comprising a second roller; an element in the center connected to the first and second roller supports, wherein the first and second roller supports may move angularly with respect to the center element causing distance between the first and second rollers to be varied; first and second positioning elements that connect the first and second roller supports, respectively, to the center element; and first and second spring biased components surrounding first and second positioning elements, respectively, to allow the first and second roller supports to move to allow for automatic adjustment of the rotor.
