About this product

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.

Features and Benefitss

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
