Abstract

La présente invention concerne un ensemble pompe pour évacuer, par une forte pression, des matériaux mélangés (un mélange de liquides et de fluides) qui ont circulé dans celui-ci, et plus particulièrement un ensemble pompe ayant une fonction de mélange, fournissant une unité d'entraînement dans un boîtier afin de générer de l'énergie, et ayant en outre un boîtier comprenant une roue de surpression et une roue de mélange afin d'augmenter la pression des matériaux mélangés influents, puis mélanger ces derniers les uns avec les autres, et les transférer dans une partie de décharge, de telle sorte qu'un vortex est formé de manière à permettre aux matériaux mélangés influents d'être mélangés les uns avec les autres.
