Choose NPT for North American applications requiring a self-sealing tapered connection; select G for European or Asian systems where sealing is achieved via gaskets or sealant; and opt for ZG (Rc) when compliance with Chinese national standard ISO 7-1 tapered threads is required. Suofu NP Series pumps offer flexible port options to accommodate the diverse connection standards used globally. Read More

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.

Suofu’s micro magnetic gear pump addresses flow instability in high-precision liquid cooling for AI servers and advanced chillers. Its positive displacement design delivers ±0.1% flow accuracy, stable performance under 3–6 bar pressure, and outperforms centrifugal pumps in microchannel systems. 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
