The integration of China's gear pump industry and new energy industry has formed a technological breakthrough path centered on magnetic drive and high-precision flow control, deeply embedded in three key scenarios: battery thermal management, hydrogen fuel cell cycle, and electric power steering. From 2020 to 2025, the market size of China's automotive circular arc gear pump market will soar from 2.86 billion yuan to 5.43 billion yuan, with an average annual compound growth rate of 13.6%. The penetration rate is expected to exceed 35% by 2026. In the field of new energy vehicles, the magnetic coupling structure completely eliminates the risk of mechanical seal leakage, combined with special ceramic isolation sleeves and high corrosion resistant engineering plastics, to achieve zero leakage transportation of high-purity/corrosive media such as coolant and hydrogen. The volumetric efficiency is stable at 92% -95%, and the noise is lower than 72dB (A). Domestic manufacturers such as Shanghai Sofu and Dell have broken through the bottleneck of core materials and magnetic drive systems, and their products are widely matched with Tier 1 suppliers such as WM Motor and AVIC Optoelectronics, and are applied to battery temperature control systems of mainstream models such as BYD and NIO. At the hydrogen fuel cell end, the micro magnetic gear pump undertakes the key tasks of hydrogen circulation and humidification, achieving precise control of pressure fluctuations<1% and supporting system efficiency improvement. The industry is moving from 'replacing imports' to 'defining standards', with a localization rate of over 70% in the mid to low end market and accelerating breakthroughs in the high-end sector.
