Flowserve

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.

ADDITIONAL INFORMATION
