Why it is specified

A double seal without a barrier system is a double seal that fails twice. The pot, the tubing, the cooling coil and the instrumentation are quoted as one assembly against the seal it serves.

Typical applications

  • Agitator seal support
  • Double seals on aggressive duty
  • Hot oil circulation seals
  • Hygienic double seals

Options and executions

  • Level switch with a contact
  • Nitrogen regulator panel
  • Pre-piped and tested as an assembly
  • Pressure switch with a contact
