The article provides a retrospective analysis of the emergence of prerequisites for the creation of designs of universal pumping units: from the first patents registered in the 1940s to modern technical solutions used at industrial facilities. The possibility of industrial application in the oil industry of fundamentally new types of vane pumps with a combined design of the impeller and rotor of the electric motor, which received a recent impetus to their spread with the development of electric motor technologies, is considered. The fundamental difference between these types of pump is the transmission of the torque to the impeller not through the shaft, but through the rim of the wheel, which is also the rotor of the electric motor. The absence of a shaft provides a number of advantages, in particular, it leads to an increase in suction capacity, an increase in pressure characteristics and an increase in operational properties – all this together increases the scope of industrial application of new types of pumps. One of the potential applications of a compact pump of the horizontal type can be the rocking of a frozen oil pipeline by tapping the coil at special points of the pipeline route. From the point of view of transporting high-viscosity oil, the design of this type also looks promising; in addition, the possibility of influencing the transported medium by an electromagnetic field is noted. The possibility of using removable impellers of various types for a hollow pump-electric motor is considered, which can significantly increase the scope of application of new types of pumps.
