Moretec ferrofluid seals utilize magnetic fluids—engineered liquids with suspended magnetic nanoparticles—to achieve hermetic, non-contact sealing in demanding environments. With outstanding cleanliness, low volatility, and stability, these seals provide long-lasting reliability in semiconductor, vacuum, and advanced industrial applications.
In rotary feedthroughs, ferrofluid is magnetically retained to form multiple liquid O-ring stages. This enables a hermetic, non-wearing seal that supports high rotational speeds and moderate differential pressures, ensuring vacuum integrity and reliability over long service life.
Ferrofluid seals play a vital role in semiconductor manufacturing and vacuum furnace processes such as annealing, brazing, and sintering. They provide stable rotary sealing in ultra-clean, high-vacuum environments, preventing contamination and ensuring consistent product quality for advanced electronics and optics.
Moretec offers customized ferrofluid formulations and seal designs to meet unique requirements in optics, aerospace, and emerging technologies. Using advanced simulation and manufacturing controls, we deliver optimized solutions tailored to specific environmental and performance demands.
