Spring energized seals is a U,V or C - shape spring energized seals function with single acting sealing element. The spring
which energizes the PTFE jacket actuates the sealing legs(lips) of the seal. The system pressure assists the spring in creating
a leak tight seal between the sealing lips and the mating metal parts. The springs assist in slight misalignment, jacket wear,
and maintaining a consistent sealing pressure against the desired target.
Spring energized seals has been designed specially to overcome the problems associated with PTFE composite or other
high performance plastic like UHMW-PE and elastomer. They are suitable for static rotary, and reciprocating application in
temperatures from cryogenic to 300ºC , pressure from vacuum to 700kg/cm², and speed up to 20m/s, to survive the most
corrosive environment.
Advantages of HiPerSeal
-Excellent dry running capability and high sealing efficiency after a short running-in period
-Reduced wear and friction due to better sealing material characteristics
-Versatile sealing pressure through various spring and seal profile design
-Excellent chemical and thermal resistance
-No volumetric change caused by swelling or shrinkage, good dimensional stability
-Compact seal, well fit in standard O-ring grooves in accordance with AS568A
-Very long shelf life
-Sterilize in autoclaves or with any possible agen except radioactive radiation
-Prevent any contamination from the seal
-No stick-slip effect even at very low speed
-Very low friction
-Very small start-up or breakaway force especially for prolonged period out of operation or intermediate operation.
