Project Background: A municipal water utility company in Moscow, Russia, faced issues with its existing water supply infrastructure—specifically, aging equipment characterized by high energy consumption and a susceptibility to freezing and clogging during the winter months. Consequently, there was a critical need to replace these units with high-efficiency centrifugal pumps specifically engineered to withstand extreme cold environments.
Solution: We provided a customized solution consisting of 32 D-type multi-stage centrifugal pumps. These units were constructed using cold-resistant materials and incorporated specialized thermal insulation structures. Furthermore, the hydraulic models were optimized to significantly enhance energy efficiency. With flow rates ranging from 100 to 300 m³/h and heads between 50 and 150 meters, these pumps were perfectly tailored to meet the demands of large-scale municipal water supply operations.
Project Results: After two years of operation, the equipment has demonstrated a 22% reduction in energy consumption. Moreover, there have been zero instances of freezing or clogging-related failures during the winter season, and water supply stability has improved to 99.7%. In recognition of this outstanding performance, the client awarded us the title of “Supplier of the Year.”
