Dry-Running Secondary Containment Seal
Mechanical Seal Style FCS
An economical option for applications where the highest level of safety and environmental control is necessary.
In certain processes, dangerous and volatile fluids require additional precautions to protect personnel, ensure safe operation, and prevent downtime. The Flexaseal Fluid Containment Seal (FCS), allows monitoring of any primary seal leakage and functions as a secondary containment seal in the event of any primary failure. The FCS is a contacting, dry-running multi-spring pusher seal which can be added to most of Flexaseal’s single cartridge options, including:
-
Style 58 heavy duty API stationary multi-spring cartridge seal
-
Style 53A API rotating welded metal bellows cartridge seal
-
Style SMS stationary multi-spring cartridge seal
-
Style RB rotating welded metal bellows cartridge seal
FEATURES:
Lightly loaded seal face minimizes wear and face temperature
Extended seal face has long wear life
Balanced design minimizes heat generation and power consumption and guarantees stable operation under worst-case containment scenarios
Isolation bushing keeps normal inboard seal leakage away from the FCS seal
Dynamic drive ring prevents pin-wear hang up
Most commonly used with API 682 Plans 72, 75, and/or 76
