OEM & 特殊工况密封 - CIRCPAC MD CIRCUMFERENTIAL BUSHING

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

运行参数

Pressure: vacuum to 6.9 bar (100 psi)

Temperature: -40 to 593°C (-40 to 1100°F)

Speed: up to: 46 m/s (150 fps)

Sizes: 35 to 457 mm (1.375 to 18.000 inches)

特点&优势

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
