All of the following ranges of double cartridge stationary seals have:

  • Hydraulically double balanced seal face technology for reduced power consumption with the ability to withstand pressure fluctuations
  • Non-shaft fretting sleeve elastomer and positive set screw shaft drive
  • Independent seal face design to enhance safety containment of process fluid in the event of damage to any individual sealing element
  • Multiple spring seal face loading with hydraulic pressure balanced for improved reliability and seal performance
  • Stationary design which allows for some angular shaft to equipment housing misalignment and is suitable for high speed applications
