Since its founding in 2011, SoliVac Engineering Ltd. has been manufacturing custom rotating feedthroughs for sputtering equipment and repairing units produced by other manufacturers. Building on the expertise accumulated over the years, we have decided to launch our own range of ferrofluid technology-based rotating feedthroughs starting in 2025.
Ferrofluid Magnetic Feedthroughs: Functionality & Advantages
Ferrofluid magnetic feedthroughs are specialized sealing solutions that enable airtight and leak-proof sealing of rotating or moving shafts in vacuum or high-pressure systems. These feedthroughs are widely used in industrial and research fields where maintaining a hermetically sealed environment is crucial.
Operating Principle
A ferrofluid is a special colloid consisting of magnetic nanoparticles suspended in a carrier liquid. Under the influence of an external magnetic field, the ferrofluid forms a dynamic yet leak-proof seal.
The main components of a ferrofluid magnetic feedthrough include:
- Ferrofluid – A liquid containing nanoscale magnetic particles that create a stable seal when exposed to a magnetic field.
- Permanent Magnets – Ensure that the ferrofluid remains in the correct position.
- Rotating Shaft and Bearings – Enable smooth shaft movement through the seal.
- Multi-Ring Magnetic Sealing System – Enhances sealing efficiency, allowing for higher vacuum levels and pressure resistance.
Innovative and Reliable Sealing Solution
Ferrofluid magnetic feedthroughs provide an exceptionally reliable and innovative sealing solution where traditional seals fail due to extreme vacuum, pressure, or temperature challenges. With SoliVac’s expertise, we are bringing a cutting-edge, high-performance product to the market in 2025.
Applications:
- Semiconductor & Electronics Industry – Vacuum chambers, plasma technology
- Medical Instruments – MRI-compatible moving components
- Aerospace – Precision instruments operating in a vacuum
- Robotics & Automation – Hermetically sealed moving systems
- Scientific Research – Particle accelerators, vacuum systems
KF Flange
Flanged - flange at the vacuum-side end of the housing
Threaded - thread on the outer surface of the housing
Threaded - thread on the stud at the end of the housing
Key Advantages:
Outstanding Vacuum and Pressure Resistance
Ferrofluid seals ensure the reliable operation of hermetically sealed systems, even in ultra-high vacuum (UHV) or high-pressure applications.
Leak-Free Performance
No mechanical contact within the seal minimizes wear and particle generation, making it ideal for semiconductor manufacturing and aerospace applications.
Long Service Life & Low Maintenance
Unlike traditional mechanical seals, ferrofluid does not degrade easily, significantly reducing maintenance costs.
High-Speed Rotation Capability
Minimal friction allows ferro-liquid seals to function effectively in high-speed applications.
Chemical Stability & Wide Temperature Range
With the appropriate ferrofluid selection, these feedthroughs can be used in extreme temperature and chemical environments.
