Abstract: An airlift for lifting liquids and pulps, comprising a suction unit for sucking in a mass being transported, an air duct for the supply of compressed air and a mixer for mixing compressed air with the mass being transported. The mixer is in communication, via a pipeline, with the suction unit and the air duct. Transfer of the mass being transported from the mixer to an air separator is effected with the aid of another pipeline provided in the airlift. The mixer is rigidly fixed to this pipeline and the air duct. The air duct and the pipeline for lifting the mass being transported have vertical portions, each consisting of at least two pipes fitted one into the other and capable of vertical movement relative to each other. The air duct and the pipeline are communicated with a lifting gear for transfer of the lower pipes of the air duct and the pipeline in the vertical direction together with the suction unit and the mixer.
