Key Advantages
1. Ultra-high Purity Material, Zero Ion Precipitation
The wetted parts are made of dedicated electronic-grade high-purity materials with special purification treatment. Compared with standard magnetic pumps, it greatly reduces precipitation of metal ions and organic impurities, effectively preventing contamination of high-purity reagents and photoresist solutions, and is ideal for high-cleanliness processes such as semiconductor manufacturing.
2. Precision Micro-flow Delivery with Low Pulsation
Built with an elaborate hydraulic structure, the HD70R precision chemical magnetic pump delivers superior flow control accuracy and extremely low fluid pulsation. It will not affect the composition of precision chemicals and meets the strict requirements for highly stable flow and pressure in electronic production.
3. Full Mirror-polished Dead-space-free Flow Channel
The integrally streamlined pump cavity is fully mirror polished without splicing gaps, exceeding the cleanliness standards of ordinary clean pumps. It leaves no residue after cleaning and fundamentally avoids cross-contamination between different high-purity media.
4. Full Sealed Protection Against External Particles
As part of the ultra clean magnetic pump system, the fully enclosed structure blocks workshop dust and suspended particles from entering the pump. It fits the operating environment of electronic dust-free workshops and keeps the conveyed media in ultra-clean condition at all times.
5. Long-term Stable Operation for Non-stop Production
Precision-calibrated transmission and support components ensure ultra-low vibration and noise as well as outstanding fatigue resistance. The pump supports 24/7 continuous operation to guarantee uninterrupted production on electronic production lines.
Typical Applications
● Closed-loop transportation of semiconductor photolithography developer
Adopting dual material purification treatment, the HD70R electronics magnetic pump eliminates trace metal ion precipitation, prevents photosensitive failure of photolithography chemicals and stabilizes wafer yield.
● Low-pulsation branch transportation of ultra-pure water for panel factories
Equipped with self-developed low-pulsation hydraulic impellers, this precision chemical magnetic pump keeps water flow fluctuation below 3% without destroying the stable molecular structure of ultra-pure water, complying with strict ultra-pure water transportation standards for panel yellow-light workshops.
● Alternating transportation of multiple photoresist strippers in dust-free workshops
Featuring full mirror polished seamless flow passages and fully enclosed outer protection, it avoids cross-contamination of liquid chemicals and blocks suspended airborne particles from mixing into conveyed liquids in dust-free workshops.

FAQ
Q: Will metal ions precipitate during semiconductor chemical liquid transfer due to insufficient material purification grade?
A: Excessive ion precipitation will not occur under compliant working conditions. The wetted PTFE components of HD70R precision chemical magnetic pump adopt dual purification processes of "primary powder screening and secondary vacuum sintering" to remove embedded metal debris inside powder. The third-party factory test shows that the metal ion precipitation is steadily ≤0.1ppb, which complies with SEMI S22 standards for high-purity semiconductor fluids. It supports 24/7 uninterrupted closed-loop transfer and avoids contamination of semiconductor precision chemicals.
Q: Can airborne particles in dust-free workshops enter the pump cavity through heat dissipation gaps and disrupt semiconductor and panel production?
A: It will not happen under standard dust-free working conditions. Adopting a closed sandwich passive heat dissipation structure, HD70R electronics magnetic pump eliminates all exposed hollow heat dissipation holes. Anti-static PTFE microporous dust-proof gaskets are installed at all drive-end gaps, which satisfy heat dissipation demands of magnetic components and intercept airborne particles larger than or equal to 0.05μm, meeting usage requirements for ISO Class 1 dust-free workshops.
