When designing pumping equipment the question arises not only of the improvement of the existing types but also the search for a new principle of uniting the supporting elements with the elements of the formation of the working cameras of the pump. The purpose of the work is to provide a substantiation of the possibilities and expediency of designing a de-axial pump based on the Rolomite mechanism. Conditions ensuring the efficiency of the mechanism are considered on the basis of a specific hydraulic pump; the principle of inlet and outlet windows placement is justified. Analytical calculation of camera areas with the help of the created model in SolidWorks is provided and the coefficient of liquid compression is determined. The graphs of changing the areas of large and small cameras are presented. The use of an electromagnet as a drive makes it possible to transfer the rotation into a closed space, which makes it possible to abandon bearings, seals, and also significantly simplifies the technological process of pump elements manufacturing. The flexible tape allows reducing the slip friction and getting a separate camera, which makes it possible to pump two substances at a time. There is also a process of liqui magnetization in the pump, which reduces the corrosion of metal elements of the pump and the pipelines. Considering the benefits of these types of mechanisms, there is the prospect of their further research and implementation.
