The value that Semlon products bring to you
During the entire life cycle of a pump, from purchase/installation to operation/maintenance to scrapping, the cost of electricity consumption and maintenance accounts for 52% of the total cost.
After equipping a 7-stage vertical pump with a rated power of 68.9KW, 380V/50Hz, speed of 2950RPM, and BEP flow of 100 cubic meters/hour with Semlon 6000 rings, the electricity bill can be saved by 43,490 yuan per year.
(Calculated based on the industrial electricity price of 0.8 yuan/kWh)
