FIELD: oil and gas industry.
SUBSTANCE: invention is related to device for pumping gas suspensions, in particular fibrous suspensions. The device comprises fluidising rotor (2) with one or more vanes (5), pump impeller and pressure tube (7). The fluidising rotor (2) is located in the pressure tube (6) of the pump (1) and has a hub (3). The centre of the fluidising rotor (2) input end (4) is made hollow and the vanes (5) are operated freely without synergy or mutual coupling. The ratio of the fluidising rotor (2) free length (FI) to the fluidising rotor diameter (Dr) is from 0% up to 75%.
EFFECT: invention may ensure the required stability for all application areas.
