Advantages over elastomer seals

 

Spring-assisted seals offer many decisive advantages over conventional elastomer seals:

AdvantageSpring-assisted sealElastomer seal
Temperature range-250°C to 300°Climited, often <150°C
Chemical resistanceuniversal, even with aggressive mediaoften limited to certain media
Pressure resistanceup to 120 MPa static, up to 50 MPa dynamicusually lower
Service life / maintenancevery high, low wearoften higher maintenance requirements
Dynamic loadhigh load capacity, little stick-slipProblems with stick-slip possible
Friction / energy losslow, good in dry runninghigher, critical in dry running
FDA conformity / biocompatibilityavailabledependent on material

 

Additional advantages:

  • Vibration and oscillation damping due to the spring
  • Minimal leakage, ideal for critical media such as hydrogen
  • Low breakaway forces and high reliability even after standstill

 

Spring types in spring-assisted seals

The type of spring has a significant influence on the functionality and suitability of the seal for different applications. The main spring types are

Spring materials and areas of application

  • Stainless steel as standard for a wide range of applications.
  • High-performance alloys such as C-276, Elgiloy or Inconel for corrosive and high-temperature resistant requirements.
  • The spring force is selected to precisely match the application to ensure optimum sealing performance and a long service life.
