Kuntai Magnetic Levitation Wins Bid for Dewar Molecular Pump, Entering the Vacuum Segment of Nuclear Fusion

Recently, Anhui Public Resources Trading Group Project Management Co., Ltd. officially released the "Dewar Molecular Pump (Second) Bid Winning Result Announcement." Hangzhou Kuntai Magnetic Levitation Technology Co., Ltd. (hereinafter referred to as Kuntai) successfully won the bid for this project by virtue of its independent R&D strength in the field of high-end magnetic levitation equipment, with a bid amount of RMB 5,823,342, marking that the domestically produced magnetic levitation composite molecular pump has officially entered the vacuum core supporting segment of controlled nuclear fusion devices.

In the complex operation process of nuclear fusion devices, the vacuum system plays a crucial role. As key core equipment for obtaining ultra-high vacuum environments, magnetic levitation composite molecular pumps feature excellent characteristics such as no mechanical contact, low vibration, and long service life, and are mainly responsible for achieving the extremely high-standard "vacuum acquisition" link in vacuum systems. The Dewar molecular pump won in this bid will directly serve the construction of extreme vacuum environments for major scientific facilities, which is of great significance for ensuring the stable operation of nuclear fusion experimental devices.

Kuntai was founded in 2022 by a doctoral team from Beihang University, and has long focused on magnetic levitation technology R&D and the localization of core components for high-end equipment, with business covering strategic emerging industries such as semiconductors, new displays, and high-end scientific research equipment. The company's core team is led by 13 Beihang Ph.D.s and has a cross-disciplinary technical team of over 100 people spanning six major disciplines: electricity, magnetism, mechanics, thermal, machinery, and control, among whom Ph.D.s account for approximately 60%, possessing profound technical accumulation in the field of high-end magnetic levitation design and manufacturing.

As a globally leading provider of micro and special magnetic levitation technology application solutions, Kuntai is currently the only core team in China that has successfully broken through the technologies of magnetic levitation composite molecular pumps and fully active magnetic levitation textile machines and achieved large-scale mass production. Its related molecular pump products have previously completed rigorous verification and achieved batch application at leading enterprises in the fields of semiconductors, display panels, and high-end scientific research instruments. The successful bid for this nuclear fusion vacuum project not only verifies the reliability of its high-end products under extreme operating conditions, but also injects strong momentum into the independent and controllable supply chain of China's cutting-edge clean energy equipment.
