API Dry-Running Secondary Containment Seal
API SEAL FCSA
Designed for Safe Fluid Containment & Environmental Emission Control
In some industrial processes, the handling of hazardous and unstable fluids demands extra measures to safeguard personnel, guarantee operational safety, and minimize disruptions. Engineered with precision, the Flexaseal Multi-Spring Fluid Containment (FCS) Seal stands as an economical choice for scenarios demanding top-tier safety and environmental management. Acting as both a primary seal with leakage monitoring capabilities and a secondary containment seal in case of primary seal failure, the FCS Seal ensures comprehensive protection and operational continuity.
The FCSA Seal 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
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 FCSA seal
Dynamic drive ring prevents pin-wear hang up
Most commonly used with API 682 Plans 72, 75, and/or 76
