In a peristaltic pump system, the pressure rollers (74) are driven by a gear reduction system and are structured and arranged to revolve through a chamber (11) in contact with a flexible tube. The pressure rollers (74) are incorporated into the gear reduction system and are driven by a follower gear (15), which in turn, is driven by a drive gear (19). The pump system further includes a cassette body (62) having a reaction surface (62A); a flexible tube mounted adjacent the reaction surface (62A); and roller gears (70) carrying the pressure rollers (74); and a cassette cap (64) for connecting the roller gears to the cassette body (62).

Dans un système de pompe péristaltique, les rouleaux de pression (74) sont entraînés par un système de démultiplication et sont structurés et disposés pour tourner à travers une chambre (11) en contact avec un tube élastique. Les rouleaux de pression (74) sont incorporés dans ledit système de démultiplication et sont actionnés par une roue dentée (15), qui à son tour, est actionnée par une roue menante (19). Le système de pompe comprend aussi un corps de cartouche (62) doté d'une surface de réaction (62A), un tube élastique monté adjacent à ladite surface (62A), et des roues de rouleaux (70) portant les rouleaux de pression (74), et un couvercle de cartouche (64) servant à relier les roues de rouleaux (70) audit corps de cartouche (62).
