Abstract
A cell for pumping a multiphase effluent includes two rotary parts ( ), the first one ( ) having a hydraulic wheel designed for transmitting kinetic energy to each of the multiphase effluent phases entering cell ( ), and the second one ( ), following the first, being an energy converting device designed for homogenizing the phases, transferring kinetic energy between the phases, entraining the lightest phase, converting kinetic energy into pressure and compressing the homogeneous effluent before it leaves the cell. All of the rotary parts of the cell are mounted on a common shaft ( ) axially arranged inside a fixed housing ( ) having an inlet and an outlet for the multiphase effluent.
