Abstract
A peristaltic pump for conveying fluids includes a stator and a rotor supported therein. A flexible hose is integrated in the stator and the rotor includes radially arranged conveying elements which squeeze the hose over a section containing the fluid. The squeezed fluid section moves progressively in the hose under the effect of a motor connected to the rotor. The conveying elements are designed as rotatably mounted rollers that include at least two rolling bearings, of which the outer rings are connected via a common outer sleeve and of which the inner rings are connected to the rotor. Under the effect of the motor, the rotor moves in the stator and the outer rings of the conveying elements roll on the inner surface of the stator.
