Rotary Union ROTOVAC
Vacuum Rotary Feedthrough with ferrofluid sealing technology
Your benefits with Vacuum Rotary Feedthrough ROTOVAC
Wear-free ferro-fluid seal
The sealing element of the ROTOVAC consists of fluid magnetic O-rings held in position by a ring-shaped magnetic field. ROTOVAC unions are wear-free and can transfer gaseous media at pressures of up to 1 bar or vacuums up to 10-8 mbar.
Reducing drive power and costs
As compared to polymer seals, the ROTOVAC magnetic fluid seal has almost no friction and just a minimal stick-slip effect. Drive power is reduced significantly.
Particle-free vacuum – process purity assured
Since there is no abrasion between shaft and sealing element, the vacuum area remains free of particles. This high level of process purity is further supported by maintenance-free sealing elements and the non-reactive magnetic fluid.
