  • Highlights

    • Each fiberglass tank sump includes a sump base, a riser, a reducer collar (factory-fiberglassed to the riser), and watertight sump shield with strap-down cover.
    • Available in 42” and 48” base diameters.
    • Reducer collars and reducer sump shields allow any tank sump to fit under a 36” manway while providing a 30” diameter clear opening for easy access to equipment.
    • Constructed from rugged ¼” thick, three-layer, hand layup fiberglass reinforced polymer (FRP).
    • White gel coat interior provides a vapor and watertight barrier and superior visibility.
    • Single wall models are available with or without bottom for various mounting options.
    • Double wall models are only available with a bottom for mounting to tank collar.
    • Double wall models are shipped under vacuum with a vacuum gauge installed for verification at site of sealed interstitial.
    • Octagonal base sumps feature a two-piece design that eliminates confined spaces and gives installers full access to the containment during installation.
    • Once equipment installation is complete, the two-piece design is connected using a fiberglass seam kit (ordered separately) to ensure a seamless, watertight joint.
    • Eight flat panels are molded into the bottom section of octagonal base sumps to provide 90° pipe entries.
    • The watertight sump shield keeps liquid out of the containment space during normal operation while allowing easy access to the containment space for maintenance or inspection.
    • Six strap down toggles and internal D-gasket ensure the cover stays in place.
