Peristaltic pump

Abstract

Abstract The peristaltic pump comprises several cylinders (5) rotated by a planetary gearing from a central gearing (3); these cylinders are rolling over at least one hose which conducts the fluid through compression of the free section of the hose. There is provided a counter-pressure body (11) passing the hose (10) against at least a cylinder (5); this body is held on a base plate (15) so as to slide in a radial direction with respect to the central gearing (3); it is taut by at least one spring towards the central gearing (3) Upon replacing the hose, the new hose is thereby located only within the counter-pressure body and, by tightening the counter-pressure body by means of the springs, a sufficient pressing is achieved for ensuring a functional efficiency of the pump. Furthermore, the tolerances in the mounting and the hoses are compensated by the counter-pressure body acting as a spring.
