The Wayne SPF50 is a submersible sump pump with a 0.5 HP motor and integrated vertical float switch designed to automatically remove water buildup from basements and crawl spaces. With a maximum flow rate of 4300 GPH, this pump keeps sump pits under control. The automatic float switch monitors water levels and activates the pump without manual intervention.
The pump's top suction design reduces clogging and prevents air lock conditions that can interrupt operation. Its epoxy-coated motor housing and reinforced thermoplastic pump base resist corrosion in wet environments. The sealed bearing system operates quietly, making it suitable for basement installations. Assembled in the USA with foreign and domestic parts, this pump is built to handle the demands of residential sump applications.
