Spf33 Submersible Sump Pump, Thermoplastic, 1/3 Hp, 3750 Gph

The Wayne SPF33 is a 1/3 HP submersible sump pump engineered to remove standing water from basement sumps, crawl spaces, and similar low-lying areas. Built with epoxy-coated steel and reinforced thermoplastic construction, this pump delivers reliable performance in wet environments where corrosion and durability are concerns. The integrated vertical float switch with a polypropylene float enables automatic operation, eliminating the need for manual on-off switching.

The Wayne SPF33 addresses water removal challenges with robust construction, proven reliability, and a design tested to 1 million cycles. Its unique top suction design eliminates the need for weep holes while reducing clogging from debris and preventing air lock conditions—common problems that can disable less-thoughtful pump designs.

Features and Benefits

• High Flow Rate: Delivers up to 3,750 gallons per hour at 0 feet of discharge lift, with 2,718 GPH at 10 feet of head, ensuring fast water removal from sump basins.
