Secondary Containment


The INCON™ brand secondary containment monitoring (SCM) system is designed to detect leaks in double-wall piping, tanks, and sumps. The system utilizes the siphon/vacuum port of a submersible turbine pump to draw a vacuum on these interstitial spaces. The vacuum levels are then continuously monitored to detect any potential leaks in these double-wall containments.

  • Highlights

    • Up to four different containments can be connected to each submersible turbine pump using a combination of single and dual channel TS-SCCM secondary containment control modules and secondary syphon ports.
    • The secondary containment control module collects information on all interstitial spaces.
    • Gathers system status, replenish rate, alarm, and diagnostic information.
    • Utilizes AUTO-LEARN® technology to learn the actual interstitial space being monitored based on the vacuum flow rate through a calibrated orifice for precise leak detection.
    • Alarms when vacuum cannot be maintained or when liquid is detected in secondary space.
    • Optional positive submersible turbine pump shut-down upon alarm.
    • Compatible with FE PETRO® brand submersible turbine pumps as well as Red Jacket® STPs.
    • All components necessary for installation including syphon check valve,vacuum hose, fittings and other installation accessories are available from Franklin Fueling systems.

    • Containments to be monitored must terminate inside the submersible turbine pump containment.
    • Installer must verify the vacuum limitation of each containment with its manufacturer prior to installation.


    • Meets all requirements of California AB2481.
    • National Work Group approved.


    Secondary containment monitoring uses the siphon port of the submersible turbine pump to draw and maintain a vacuum on the secondary containments of lines, sumps, tanks and vapor lines. During installation a calibrated leak is introduced during the AUTO-LEARN™ process which allows the system to learn the vacuum characteristics of each containment space. The vacuum level is continuously monitored and compared to established leak rates to ensure that the secondary containment is tight.
