“…The appropriate brand is selected to achieve the optimal pressure-supply value based on the tasks set before the unit. Submersible-type pumps are equipped with a safety valve that regulates the water column in the event of a sudden engine stop, facilitates restarting, and protects the rotation of the blades in the opposite direction [11].…”

Submersible pumps are the leading electricity consumers in centralized water supply systems. Considering the cost structure of the life cycle of pumping equipment, the main costs should include investment costs, electricity costs during operation, and costs of repairing pumping equipment. Considering the growing cost of electricity in the world, the cost of manufacturing pumping equipment is significantly increasing, which in turn causes an increase in its price. The key factor in increasing the competitiveness of such equipment on the market is its modernization with the achievement of a higher level of energy efficiency with a simultaneous reduction in cost due to a reduction in weight and dimension parameters. In the research, a significant increase in the head from 15 m to 65 m of the submersible pump stage was achieved by increasing the rotation frequency from 3000 rpm to 6000 rpm and designing the pump for this rotation frequency. As a result, the pump head, created by the flowing part with the basic stage (eight pieces), can be provided by the pump using only two designed stages. It creates the prerequisites for reducing the mass of the pump from 200 kg to 45 kg, or by 77.5%. Also, in designing the pump, energy efficiency was increased from 74.6% (for the existing pump) to 79.4% (by 5% for the developed pump). The research results made it possible to significantly contribute to reducing the cost of the life cycle of the submersible pump installation.

Pumping equipment consumes about 20 % of the electrical energy produced by humankind. A significant, even drastic, reduction in the weight and size indicators of pumping equipment leads to a decrease in the cost price and, therefore, competitiveness of such products in the market. Simultaneously, it makes it possible to use more valuable and high-quality construction materials and technologies that improve the reliability of equipment and its energy efficiency, which in turn is a clear step in solving many UN Sustainable Development Goals (SDGs). According to the research results, it was proved that by increasing the frequency of the drive, it is possible to reduce the mass and size indicators of the submersible pump for the needs of the critical infrastructure sector by reducing the number of stages. Mainly, the amplitudes of oscillations near the rotation frequency are 12–22 % and do not exceed 35 % of the gaps in the seals, as required by the available international standards to ensure the guaranteed vibration reliability of the pump. Overall, using a bearingless support design will significantly increase the reliability of the developed pump.
