The elliptical rotor begins to squeeze the hose 9 completely when the major axis is perpendicular to the bottom of the pump body 17. The rotor 4 is provided with an external thread on the right side of the pump shaft 20. And the right end surface of the rotor is axially positioned by mounting a positioning nut on the external thread on the right side of the shaft section.
