Abstract

Cette invention concerne une pompe (1) de type péristaltique qui incorpore un tube flexible (21) en matière composite, constitué d'un tube interne primaire (2) conçu pour contenir un fluide primaire à pomper et d'une chemise externe (15) contenant un fluide secondaire. Un organe de compression (25) est conçu pour produire périodiquement des ondes de compression péristaltique le long du tube composite (21) de manière à induire un flux du liquide primaire à travers le tube primaire (2). Un conduit (40) dirige un flux, à contre courant, du fluide secondaire à partir d'une section aval (41) vers une section amont (42) de la chemise externe (15), ce qui tend à dilater le tube primaire (2) et augmente la pression d'aspiration en amont des ondes de compression.
