Internal Balanced Component Mechanical Seal

The SMI is a hydraulically balanced internal rotary single component mechanical seal for use with a number of stationary face arrangements.

Features:

  • Non-shaft-fretting design to reduce cost of equipment overhaul
  • Maximizes seal life in suspensions and liquids such as slurries given the smooth non-clogging profile (springs out of the product)
  • Hydraulically balanced seal face
  • Sizes available from 0.750" to 6.000" (18mm - 155mm)

Depending on condition, all first4seals cartridge seals can be fully refurbished.
