A major paper production company faced significant energy wastage and operational inefficiencies with their aging vacuum system comprising five roots vacuum pumps. These pumps, fitted with a total motor power of 560 kW, were running at an actual power of 430.53 kW. Due to the prolonged use and obsolescence of the equipment, the operational energy consumption was excessively high.

The professional team of Xinran conducted a thorough site survey and technical discussion, deciding to upgrade the old system with two XRC110 magnetic suspension turbo vacuum pumps. Once powered, the magnetic suspension bearing system stabilized the motor's rotor, allowing it to operate without physical contact. Driven by a high-speed variable frequency drive, the impeller continuously worked on the gas, creating a stable vacuum inside the intake pipe. Compared to traditional liquid ring vacuum pumps, this eliminated friction losses from bearing rotation and provided a 100% water-free and oil-free operation, resulting in lower noise, reduced vibration, and significantly decreased energy consumption per ton of paper produced.
