TYPE TBM

The "Sealergy Seals Type TEFLON MG1" refers to a mechanical seal that combines features of the industry-standard Burgmann MG1 seal with a Teflon (PTFE) below. The standard MG1 seal uses an elastomer bellows, while this variant uses a Teflon bellows to provide superior chemical resistance. This type of seal is ideal for applications in the chemical, petrochemical, and pharmaceutical industries where highly corrosive fluids are present. The primary reason for choosing this seal is the use of a Teflon (PTFE) bellows as the secondary sealing element. This material is highly inert and can withstand a wide range of corrosive and aggressive chemicals, including strong acids and alkalis, where traditional elastomer bellows would fail or degrade. The seal maintains the robust and simple design of the MG1, which is a single-spring, unbalanced seal with a rotating bellows. This makes it a dependable and versatile choice for a broad range of rotary equipment, such as pumps, mixers, and agitators. Teflon bellows can operate effectively in a wider temperature range than traditional elastomer bellows, making the seal suitable for both cryogenic and high-temperature chemical applications. The single-spring design is less prone to clogging than multi-spring designs. Its simple construction and compatibility with the MG1 standard make it a cost-effective solution for chemical applications, as it provides a longer service life in corrosive environments.
