Silicon carbide seal face utilizes Flowserve Precision Face Topography with a bi-directional wave pattern that narrowly separates the seal faces for long-term, reliable performance
Fitted with a contacting or non-contacting inboard seal, the low emission design helps meet the most stringent emissions requirements, especially in light hydrocarbon services with a vapor disposal system back pressure below 25 psi (1.7 bar).
Unpressurized containment seal operation may include support system Plans 72, 75, 76 for simplified maintenance
High and low pressure liquid backup seal capability allows for safe and convenient equipment shut down if the primary seal fails at pressures up to 600 psi (41.4 bar).

Minimal inventory is required to reconfigure a GS seal in an existing dual seal and upgrade to non-contacting wave face reliability.
Cartridge assembly simplifies installation for a quick and trouble-free start-up.
Remote performance monitoring is available within the standard piping plans to report status of the primary seal and reduce downtime.
Available as a single seal for equipment such as low pressure blowers and vertical sump pumps where dry running and low emissions are required.
