Circpac MD seals are a segmented circumferential seal designed for fans, blowers, dryers, turbines, centrifuges and other rotating equipment. Circpac MD seals come packaged in a convenient split housing for easy installation. Standard designs consistently outperform packing, bushings, labyrinths, and felt seals with lower gas consumption over a wider range of operating conditions.

Configurations:

Single ring: Low pressures

Tandem rings: Process vent or drain

Double rings: Inert barrier gas injection

Triple rings: Inert barrier gas injection Lower barrier gas consumption rate

Quadruple rings: High pressure Multiple vent, drain, or barrier gas injection ports

Key Features

  • Floating circumferential rings are hydraulically balanced with hydrodynamic surface topography to minimize wear at high speeds and pressures
  • Standard radially split seal housing enables installation without dismantling equipment or requiring equipment modifications
  • Multiple ring configurations are available for higher pressures, process venting or draining, inert gas purging, reduced emissions, and emergency backup
  • Companion inert gas support panels are available to provide adequate flow and pressure of nitrogen or other barrier gases to achieve near zero emissions
