Balanced, segmented circumferential ring seal with hydropad grooves, large bearing pads and a split housing that mounts outside the seal chamber. Hydrodynamic features reduce gas consumption over 10 times less than bushings or labyrinths. Operating window includes pressure up to 100 psi, temperature up to 1100° F, and speed up to 150 fps. Standard radial clearances of up to 0.25" accommodate thermal growth and shaft misalignment.
Features and Benefits
● 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
