This is a rugged 2HP 230V pump with a heat conducting cast iron/steel motor casing. Pumps liquid up to 120 degrees and de-waters surfaces up to 1/2. The ST30BCUL incorporates reliable double mechanical oil-filled seals, internal thermal overload protection that shuts down the pump when operating temperature becomes too high and automatically restarts once the motor cools and a proper temperature is met, sealed ball bearings, ductile iron impeller, carrying handle and molded 50' power cable with strain relief. The 6.7" diameter design permits the pump to fit into tight spaces and conduits.
