Flanged Seal

Flanged seals are a distinct category of radial seals designed for superior performance in rotary applications. These seals feature a flange — an extension of the seal’s heel — which fits into a counterbore in the housing. This design allows the flange to be pinched by the housing at assembly, providing a positive mechanical lock that ensures the seal remains stationary. This locking mechanism is crucial for applications involving rotary forces where traditional seals might fail.

The integration of a flange in these seals secures them in place and simplifies the assembly process, making them an ideal choice for equipment with end plates. Flanged seals offer a powerful design that includes redundant sealing on the static side of the gland, enhancing both durability and reliability. This design feature is especially beneficial in heavy-duty machinery where seal displacement or rotation could lead to operational failures.

Common applications for flanged seals include process machinery such as mixers, augers, and spool valves, where it is critical to contain the product. These seals are particularly effective in environments that demand high-performance sealing solutions to maintain the integrity and continuity of operations.

Materials like PTFE and UHMW-PE are frequently used in the manufacture of flanged seals due to their exceptional properties, including chemical resistance, low friction, and wide operating temperature ranges. These materials ensure that the seals can withstand harsh conditions and provide long-lasting performance in demanding industrial settings.

Flanged seals are a strategic choice for any application requiring reliable radial seals capable of handling rotational stresses. Their specialized design, ease of assembly, and robust locking mechanism make them indispensable in modern industrial applications where precision and durability are paramount.
