280 Heavy Duty Cartridge Dual Seal
The 280 Heavy Duty Cartridge Seal is specifically designed to handle demanding, high torque applications. This superior high performance product is an ideal selection for such difficult applications as high concentration black liquor, hard to seal monomers such as acrylonitrile, vinyl chloride monomer and any other potentially viscous solidifying liquids.
Enhanced Thermal Control
Unrestricted Dual Pressure Balance
The 280 provides for a 75% ratio for double or tandem barrier mode, while an instantaneous shift prevents opening under system upset conditions. The seal can run with high pressure both inside and outside because the seal balance is optimized to both the ID and OD pressure.
Internal Barrier Channel
The internal pumping system provides efficient barrier fluid flow and heat removal away from the faces. The heat transfers into barrier fluid, not into the process, for high capacity cooling.
Seal Rings Located for Optimum Heat Dissipation
The increased radial clearance provides efficient barrier fluid flow and heat removal.
