Abstract

a presente invenção refere-se a uma bomba peristáltica (2), que compreende: um rotor (4); um conjunto de trilhas (10) espaçadas do rotor (4) para receber n tubos (12) entre elas, em que n = 2m, com m sendo um número inteiro positivo ¿ 2, os tubos (12) sendo distribuídos entre si em um orifício de descarga, em que um do rotor (4) e do conjunto de trilhas (10) compreende uma superfície de oclusão para cada um dos n tubos, e em que as superfícies de oclusão são localizadas em n diferentes posições angulares, o deslocamento angular entre as superfícies de oclusão deslocando a pulsação associada com cada tubo (12), de modo a reduzir a pulsação total no orifício de descarga.
