SK1000 Magnetic Drive Mixer Operating Principle • A Magnetic seal comprises of a sealed chamber (Shroud), which contains a rotating Inner Shaft, which is embedded with powerful Inner Magnets. This inner shaft is supported on Upper and Lower Bearings. These are special Bearings, capable of withstanding harsh environments present inside the Reactor. A special barrier filter prevents dust from entering the Bearing Area. • The output shaft of Motor/Gearbox assembly is locked on to an Outer Rotor, which is fitted with an Outer Magnet Assembly. When the Motor is switched on, the Outer Rotor Rotates, and magnetic flux causes the inner shaft to rotate synchronously with the Outer Rotor. • Top Entry Magnetic Seals are the safest method for sealing agitated Reactors. Their applications include High Pressure Autoclaves such as Hydrogenators, as well as Reactors used for handling sensitive or hazardous • SunKaier manufactures a wide range of Top Entry Magnetic Seals, for use in their Reactors. These are suitable for Reactors of up to 50000 liters capacity, temperature up to 300° C, and for pressure up to 100 Bars. Reactors of higher capacities and ratings can be supplied with special designs. Advantages of Magnetic Sealing 100% sealing, ZERO leakage Long equipment life Touble free operation Zero emission of hazard fluids Minimal friction saves power Suitable for pressure fluctuation - Outer Rotor Rotor / Stator SK1200 Magnetic Drive Mixer Sunkaier Magnetic Mixer Sunkaier magnetic mixer consists of a weld plate and a mixer unit including gear drive. The static male bearing is secured to the vessel's tank plate and the rotating female bearing is integrated and sealed into the mixing head, or rotor, of Sunkaier magnetic mixers utilize sliding bearings between the mixing head and male bearing. These bearings are manufactured from Silicone Carbide (SiC) which is among the hardest substances known. Due to this hardness, it makes for an excellent long lasting bearing material for rotating equipment in wet
