Using magnetic fluid as sealing material for film-coating machine,sinter furnace, brazier, vacuum pump sealing power drive.

Magnetic Fluid Seals

  

These are updated new sealing products. We using nm class magnetic fluid instead of rubber O-ring to provide high vacuum sealing and power transmitting performance.

   

Compared with normal mechanical seals, this kind of seal owns the following features:

1. Long life: magnetic fluid rings are in nearly zero wear-out.Seals life depends on bearing life;

2. Perfectly torque transmitting: as it is in magnetic liquid sealing, there is nearly no torque loss;

3. Quite low leakage: they are designed for the vacuum environment with 10-12 Pam3s-1 leakage rate only;

4. Fit for different rotating speed;

5. Good pressure resistance: the capacity can reach to 0.25 MPa

    

   Fluid Sealing feed-throughs have been widely used in sealing various vacuum equipments, like, vacuum furnace, sinter furnace, brazier, hardening furnace, heat-treating furnace, monocrystalline silicon furnace, vacuum pump, film-coating machine, chemical gas deposit equipment, ion beam etching machine, molecular pump, ultrahigh-speed centrifugal machine and so on.

   

We can design special magntice fluid sealing feedthroughs as per customers' equipment requirements.

When inquiring, please tell us the mounting configuration data.
