Micro Magnetic Gear Pumps Support PandaX at China Jinping Underground Laboratory 2026-04-01
This article reports on the application of Suofu's NP Series micro magnetic gear pumps in the PandaX (PandaX project) experiment, a major national dark matter detection project at the China Jinping Underground Laboratory (CJPL). Cited in a paper published in the International Journal of Refrigeration, these pumps were selected as the core driver for the coolant circulation within the experiment's critical cooling system. The article details how the technical features of Suofu's pumps—including their leak-free design (using magnetic couplings), ultra-low temperature tolerance (down to -120°C), high-precision flow control (0.1% precision), and high-pressure output—perfectly met the stringent requirements for safety, stability, and precision in the extreme experimental environment. The successful deployment in this flagship project demonstrates Suofu's capability in providing advanced micro pump solutions and its role in supporting cutting-edge scientific research and national s
