Our Model M84 Pedestal Sump Pump is designed to remove unwanted groundwater in basement sump applications. The 1/2 HP M84 is designed for indoor applications where the motor is mounted above the pit cover. This protects the motor from water, water spray and high humidity. This pump is not intended for use with flammable liquids. Known as the ''Old Faithful'' M84, it is a fully automatic float-operated sump pump. The polypropylene float is chemically-resistant. The corrosion resistant engineered plastic non-clogging impeller has a smooth surface allowing water and solids to pass freely through the pump.
