Vacuum rotary union ROTOVAC

2-passagelow-pressure

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.
