Single acting MG12 Mechanical Seals are suitable for handling light chemicals, waste water and pure drinking water. Designed as per global norms, these mechanical seals have rubber bellows that maintain correct alignment of these seals to avoid displacement of their shaft. These types of rubber bellows are effective in avoiding fretting or wear and rust formation of shaft. MG12 Mechanical Seals use tungsten carbide/silicon carbide/ceramic or carbon as their face sealing materials. To design their secondary sealing component, standard grade neoprene or EPDM or viton is chosen. Stainless steel ( 304/316 grade) made hardware spring of these mechanical seals is completely wear and rust protected for a prolonged service life.
