Widely adopted in semiconductor and high-density computing cooling, it offers a cost-effective alternative to valve-dependent conventional solutions. Read More

Zirconia (ZrO₂) ceramic shafts significantly outperform 316L stainless steel and alumina ceramic shafts in micro magnetic gear pumps. Offering superior fracture toughness, flexural strength, wear resistance, and corrosion resistance, they enable high precision (±0.1%), extended service life (>20,000 hours), and reliable dry-running capability. These properties make them the ideal choice for demanding applications in medical devices, semiconductor manufacturing, and chemical processing. Read More

The transition to MW-class liquid-cooled ultra-fast charging piles presents a critical cooling challenge, as centrifugal pumps struggle with the high flow resistance and viscosity demands beyond 600KW. Suofu's magnetic gear pumps, particularly the NP350 model, are positioned as a specialized solution, offering high differential pressure (7-8 bar), zero leakage, wide temperature tolerance (-55°C to 90°C), and compatibility with various coolants. These features are designed to ensure stable, high-speed coolant circulation for full-power output and minimal maintenance, addressing core requirements like overcoming line resistance and preventing leakage in high-power charging systems. The company's extensive field deployment and validation with leading operators are cited as key credentials. Read More

The selection of pipe diameters in micro gear pump systems requires specific considerations for low flow rates. For the outlet, a flow velocity of 1-3 m/s is recommended to balance pressure drop and cost. Inlet conditions are more critical due to atmospheric pressure limitations, necessitating a lower velocity of 0.5-1.5 m/s to ensure proper fluid intake and prevent issues like cavitation, especially with volatile liquids. Pipe diameter should be adjusted based on line length, fittings, and fluid viscosity to optimize overall system performance and reliability. Read More
