In an era of informatization, fragmentation, and personalization, the age of mass-produced, low-cost manufacturing—where standardized Roots pumps with only adjustable pumping speeds are universally applied across various scenarios—is increasingly failing to meet the needs of enterprises striving for refinement, customization, and high-end development. ELIVAC Vacuum Technology, an American brand with global manufacturing, originates from Europe and America and is the world's first manufacturer to offer personalized and optimized custom Roots vacuum pumps tailored to customer needs.

Today, ELIVAC is the world's first company with comprehensive independent technological capabilities in the fields of secondary steel refining (automated control) processes using mechanical pumps, dust removal, and the manufacturing and system integration of mechanical vacuum pumps. As a result, we can assist customers in transforming their existing steam-based secondary refining and degassing systems into mechanical pump systems that achieve 80% energy savings and 100% emission reductions.

Thanks to its deep understanding of vacuum and manufacturing technologies, combined with a rich portfolio of patents, Eletorch offers customers a wide range of options. Based on their specific applications, customers can select the most suitable Roots pump for every pumping speed from 110 to 60,000 m³/h.

ELIVAC API (Adjustable Pre-inlet Roots Pump for Large Pressure Differentials) significantly extends its industrial application range under harsh operating conditions. Compared to conventional Roots pumps, it achieves 2 to 10 times higher pressure differentials (within the range of 50–500 mbar), offers a higher compression ratio, and maintains stable internal temperatures even under high-pressure differentials. Additionally, it can be combined with backing pumps such as liquid ring pumps, claw pumps, and screw pumps to enhance pumping speed or vacuum level. It is widely used in upgrading traditional vacuum processes to meet industrial demands for high efficiency and low emissions.

The pumping capacity of the Eletorch ESD series screw pump is specifically optimized for key process pressure ranges (10–1000 mbar) in industries such as refined steel and large-scale chemical plants. Equipped with IE5 permanent magnet motors, it covers pumping speeds from 800 to 3000 m³/h. Within its advantage pressure range, the pumping power/efficiency ratio is 25–47% higher than that of similar domestic and international products!
