    Harsh Environment Self-Priming Dewatering Pumps

    Image of Product. Front orientation. Dewatering Pumps. Harsh Environment Self-Priming Dewatering Pumps.
    This pump has a totally enclosed nonventilated (TENV) motor that is cooled by the liquid being pumped. Also known as a flexible impeller pump, it creates a suction force that can draw liquid upward to fill the pump chamber when your liquid source is below the pump. Mount up to 6 feet above your liquid source. Pump can pass solids up to 1/4" in diameter without clogging, so there’s no need to filter sediment and debris. A handle makes it convenient for on-the-go removal of bilge water, waste oil, and spills. Pump can also be used to cool marine engines and drain liquid from holding tanks.
    Note: Pump must be filled with liquid before use. It needs a constant flow of liquid and cannot run dry.

    Pump with Intake and Discharge Tubes

    Convenient to keep in your toolkit for on-site cleanup, these pumps attach to your drill for small liquid extraction jobs, as well as draining water from clogged sinks and emptying tanks. Pumps are self-priming, which means they create a suction force to draw liquid upward. Do not use with solids.
    Note: Pumps must be filled with liquid before use. They need a constant flow of liquid and cannot run dry.
