Gas Seals

 

TF Seals' gas-lubricated seals offer advanced sealing technology in a compact and easy-to-install design. Our fault-tolerant gas seal designs offer higher reliability, reduced gas consumption requirements, and can accommodation for gas supply disruptions.  Gas seals are useful in processes that cannot tolerate any product contamination or escape into the atmosphere. They are also useful for processes or materials that are sensitive to the heat that typical mechanical seal faces generate. These seals use an inert gas to separate the seal faces. The seal faces are profiled to capture the gas and provide lift for seal face separation or light contact. With separation or light contact, minimal heat is generated.  The inert gas provides the lubrication for the seal faces and acts as a barrier against the product.​
