Product detail

 9250 series 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 actrylonitrile, vinyl chloride monomer, and any other potentially solidifying liquids and latex. The 9250 provides superior value when used in tough chemical slurries that require non-diluting environmental control and where vibration could occur.



v Unrestricted Dual Pressure balance: The seal can run with high pressure both inside and outside.

v Internal Barrier Channel: The internal pumping system provides efficient barrier fluid flow and heat removal away from the faces.

v High Torque Capability: All O-Rings located on the OD of the seal rings, allowing the O-Rings to slide to support during high torque start-ups and to prevent compression hang-up under elevated temperatures.


v Metal parts: 304SS, 316SS

v Rotating Face: Carbon, Silicon Carbide, Tungsten Carbide.

v Stationary Face: Silicon Carbide, Tungsten Carbide.

v O-Rings: EP, Fluoroelastomer, Aflasd, Perfluoroelastomer.

v Springs: 316SS, Has.Cd.


Operating Limits:

v Pressure: Up to 40 bar (600 psig)

v Temperature: Up to 260oC (500oF) Perfluoroelastomer


v Speed: Up to 20 m/s (4000 fpm)
