In case of intensive water with sand production fr om the well during oil and gas extraction, creation of special pumping equipment for harsh operating conditions is still an important objective. The main objective of scientific studies is to develop new principles of multiphase pumping in case of high concentration of solids in a stream. Known technical solutions in the area of pumping equipment: labyrinth pumps for oil and gas production; centrifugal pumps for simultaneous operation with jet pumps; pumping equipment able to operate as a reverse pump, are analyzed in the study. The current study is based on the concept wh ere complex screw type surfaces of the circulating part of the pump can be substituted with the set of flat and cylindrical surfaces that are more technological. Moreover, there is a greater variety of construction materials available, including the hardest types. Nowadays, it has become possible to reconsider some approaches for the creation of pumping equipment and labyrinth pumps in particular due to emerged ability of practical usage of additive technologies. In the new labyrinth pump development study we focused on two additive technologies: «Material Extrusion» and «Sheet Lamination».В  In accordance with first laboratory tests it is concluded that labyrinth pump characteristics are stable, but instead of constructing more complex screw-type surface it is possible to use simpler technology of rotor and stator consisting of a set of flat discs creation. The choice of the most perspective directions for further research and construction studies in order to provide effective pumping of liquids with high concentration of solids in a stream is made in the study. Further studies are aimed at creation of new pumping equipment suitable for oil and gas production if harsh operating conditions.
