The rapid expansion of AI computing has made liquid cooling essential in data centers, yet delivering low-viscosity, volatile refrigerants like Freon and fluorinated fluids poses significant technical challenges. Over 50% of pump failures stem from poor compatibility, including insufficient dry-run and self-priming capabilities. The Suofu NP series micro magnetic gear pump addresses these issues through optimized materials, gear geometry, and structural design, enabling reliable dry-running, strong self-priming, and high-pressure tolerance across diverse refrigerant types.

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
