Magnetic levitation vacuum pumps have sparked a wave of energy-saving transformation in the paper industry. After replacing the original water ring vacuum pump with two magnetic levitation vacuum pumps, a pulp and paper enterprise with an annual output of one million has achieved stable and almost maintenance free operation of the equipment, saving more than 30% of electricity compared to the original system, saving 2.09 million kWh annually, equivalent to 1.02 million yuan in electricity costs. While improving production and quality, it has also achieved a dual reduction in energy consumption and maintenance costs. The 22 kW magnetic levitation centrifugal vacuum pump from Bosen Power Technology can save more than 40% energy compared to traditional Roots blowers when applied in tissue factories, and the energy-saving effect of high-speed permanent magnet centrifugal vacuum pumps can be as high as 50% or more.
