Patent ID: 10465673

Abstract:
The invention relates to a peristaltic pump (1) comprising a saddle and a rotor (3) rotatable therein, between which a hose (4) is arranged. The rotor (3) carries hose compression means (6), which sweep over the hose (4) with the rotation of the rotor (3) and thus convey a conveying fluid. When the hose compression means (6) emerge from the hose (4), this results in pulsation effects. According to the invention, these pulsation effects are suppressed in that an inner saddle face (5), on which the hose (4) is positioned, is suitably shaped. In addition, the pulsation effects may be reduced or prevented by controlled adaptation of the rotor rotational speed, by suitable selection of a conveying end position during metering of the pumping medium, or by establishing particular invariable conveying end positions. The use of a peristaltic pump (1) of this type for metering is further proposed.
