Ceramic Components for Magnetic Pumps — Pump Shafts
Manufactured from high-purity alumina ceramic (Al₂O₃ ≥ 99.5%). Suitable for medical device applications.

- We offer high wear and corrosion resistance and are compatible with medical fluids.
- Niimi’s technical ceramics feature wear resistance, chemical resistance, thermal stability, and a non-porous structure.
- Proven materials and products with over 20 years of mass production experience.
- With precise manufacturing technology, Niimi can customize surface roughness and dimensional accuracy to meet customer needs.
- We strictly control the manufacturing process from raw material production to finishing and final product inspection.
- Reliable — Made in Japan
- Magnetic pumps employ a non-contact drive mechanism using magnetic force, significantly reducing seal wear and the risk of fluid leakage.
