    Continuous Cleaning

    Continually cleans across the entire intake with multiple scrapers (no cycle times, no clogging).

    Low Maintenance

    With no lower sprocket, FlexRake® technology allows all maintenance to be performed from the deck; no jam points underwater to require diving or confined space entry.

    Long-Life Durability

    Original FlexLinkTM multifunctional link system - with 5 lb. stainless steel cast links and an ultimate strength of 60,000 lbs. - provides unmatched durability. Many systems have been operating for more than 20 years.

    Full Range Adaptability - Unhampered by Large Debris

    Jam EvasionTM technology allows the FlexLinkTM multifunctional link system to lift and pivot around debris. This allows FlexRake® technology to adapt to a wide range of debris variations.

    Energy Efficient

    The low horsepower requirements of the Sumitomo drive system ensure low-cost, energy efficient debris removal.
