The powerful, rugged Zoeller M98 Sump Pump has sufficient power to drain flooded excavations, basements, window wells, construction sites, and swimming pools. The single-phase motor on this pump is permanently-lubricated for continuous use and hermetically-sealed to assure a long service life and dependable operation. Features include a nonclog vortex impeller and a screenless suction inlet, enabling the Zoeller M98 to be used in areas where conventional sump pumps would clog or freeze up due to the accumulation of light debris. A powder-coated green epoxy finish and stainless steel screws, guard, and switch arm limit rust and corrosion.
