The Techné energized seal is used either for high or low rotation and translation speeds, wide positive or negative temperature ranges, or whether the seal is in contact with corrosive fluids. SPRING Energized seals can replace most conventional seals.
Thanks to its very wide temperature range (-250°C to +300°C), Techné spring energized seals are a good alternative to elastomer materials, which are often limited when faced with high temperatures and aggressive environments.
The spring energized seal consists of a PTFE active part and a spring (expander). The spring ensures a good seal at both low and high pressures. It also compensates wear on the PTFE casing under high loads.
Assembly
There are 2 types of mounting
Radial (e.g. rod and piston), for predominantly dynamic applications
Axial (e.g. flange seal), for predominantly static applications
Internal axial: if pressure comes from the inside
External axial: if pressure comes from the outside
It is recommended to install spring energized seals in an open housing, and to lightly oil the components before assembly. The housing must be clean and free of sharp edges.
Applications
The spring energized seal is designed for use in a wide range of applications. It offers improved sealing performance.
Its benefits include
Universal chemical resistance
Wide temperature range
Minimal friction (even when dry)
Use at high pressures
Use for reciprocating, rotating or static movements
High abrasion resistance
Low space requirement
Resistance to high speeds
