APOG-CSFFX Dual Cartridge Seal Category 2/3 Type C 3CW-FF

TECHNICAL FEATURES

•Primarily utilized to suit the requirements of the Oil and gas industry application defined by API682.

•The sealing configuration is 3CW-FF,used for layout 3.

•Allow for greater axial displacement and radial runout.

•Integrated bidirectional flow design, unique pump efficiency ring design, and significant circulation effect of buffer/isolation liquid.

•The combination of static bellows and flexible graphite can effectively cope with various high-temperature or low-temperature working conditions.

•Static bellows design exhibits higher stability under high-speed operating conditions. Additionally, it features less mechanical wear and a longer seal service life.

•The structure is simpler and more stable than APOG-FB, making it easier to maintain.
