The 900B series is a high-performance mechanical seal designed to withstand extremely high-pressure pump applications in Upstream Oil & Gas, Refinery, and Petrochemical industries. Built with a robust construction, it delivers reliable sealing performance under extreme operating conditions while ensuring minimal face distortion at high pressures.

This seal features an innovative retainer design that eliminates the need for a thrust ring, ensuring uniform face loading and preventing uneven wear. The unique key drive mechanism enhances torque transmission, making it ideal for handling high-speed and high-torque applications.

To enhance seal longevity and reliability, the distributed flush gland design option is available for improved cooling and lubrication. Additionally, the backup ring design prevents extrusion at high pressures, ensuring consistent performance in demanding environments.

The 900B series is available in multiple configurations, including Single Acting Balanced, Dual Pressurized, and Dual Unpressurized options, making it a versatile solution for a wide range of sealing applications.
