These are  Multi-spring, externally mounted Mechanical seals, suitable for corrosive liquids. These Seals are inherently Balance. It's special design eliminates contact of metal components of seal from corrosive media. These Mechanical Seals are also available in single spring designs for specific use.

UE-TB Mechanical Seals are offered with standard GFT v/s Ceramic faces and can also be offered in Silicon Carbide faces in special application.

UE-TBR Mechanical Seals are having replaceable rotary face design. In these Mechanical  GFT face can be replaced with new one without changing other parts.

UE- TBS Mechanical Seals are having Single Open Coil spring encapsulated by PTFE for special purposes.

UE-TB Mechanical Seals are most commonly used in all kinds of Acids,  Alkalies and strong Oxidizing / Reducing agents. TB seals are entirely different from other type of mechanical seals hence contact parts are available in different materials like GFT, PTFE, Ceramic, Hestalloy, Alloy-20 etc.

These Seals can not be used for high temperature applications due to limitations of faces and body material
