The 24th international exhibition of industrial pumps, compressors, pipeline valves, drives, and motors, PCVExpo-2025, was held at the Crocus Expo Exhibition Center. The event was organized by MVK, and co-organized by the Russian Association of Pump Manufacturers and the Scientific and Industrial Association of Valve Manufacturers. Bauman Moscow State Technical University and the Electrical Machine Building Industry Union served as exhibition partners. The exhibition was supported by the Ministry of Industry and Trade of the Russian Federation.
PCVExpo-2025 showcased a wide range of industrial equipment solutions and innovations, including pumps for various industries, compressors, electric motors, shutoff and pipeline valves, seals, and components. This year, over 190 companies from Russia, China, and Belarus participated in the exhibition. PCVExpo traditionally became part of the large-scale industry project "Inter-Industry Technology Week," which simultaneously hosted six specialized industrial exhibitions: NDT Russia, Heat
The PCVExpo-2025 business program included two conferences and five thematic events, attended by over 40 speakers and a total audience of over 250 people. One of the key events was the International Scientific and Technical Conference "ECOPUMP-RUS'2025. Energy Efficiency and Innovations in Pump Engineering," where leading scientists and engineers presented papers.
At the conference, Associate Professors Vasily Shchur and Dmitry Svoboda, scientists from the Higher School of Power Engineering at Peter the Great St. Petersburg Polytechnic University, presented the results of developing and optimizing a mathematical model for the turbine section of a high-speed turbodrill, which converts the energy of drilling fluid flow into bit rotation during well drilling. The study identified key parameters affecting turbine efficiency and optimized the blade shape using modern CFD modeling methods. As a result, the turbodrill's torque and efficiency were increased, energy losses were reduced, and operational reliability in extreme conditions was improved. The resulting digital model can serve as the basis for designing next-generation multistage axial turbines.
Another report, presented by Alexey Zhuravkov, an engineer at the Hydromechanical Engineering Laboratory, focused on developing approaches to designing flow paths and calculating fluid flow in hydraulic torque converters. During the research, a new flow path for a hydrodynamic converter used in gas turbine start-up systems—drives for gas pumping units—was created. Using computational fluid dynamics (CFD) methods, the researchers determined the optimal geometry parameters and shape of the impeller and turbine wheel systems, as well as the guide vane. The developed design demonstrated a hydraulic efficiency of 86%, 7% higher than that of the production model from Voith. The results demonstrate the high potential of Russian developments in torque converters and open up opportunities for further optimization of gas turbine start-up systems.
The research conducted by the Laboratory of Hydromechanical Engineering is part of the research activities of the St. Petersburg Polytechnic University under the Priority 2030 program, which aims to develop the scientific potential of Russian universities and introduce innovative technologies into industry.
PCVExpo-2025 once again confirmed its status as a key industry event, bringing together manufacturers, engineers, scientists, and customers of industrial pumps, compressors, and pipeline valves. The event became a platform for showcasing cutting-edge technologies, promoting domestic developments, and strengthening international cooperation in industrial engineering.
