Built to last with solid Class 30 cast iron construction, the Superior Pump 92341 1/3 HP submersible sump pump is engineered for continuous residential basement dewatering. Powered by a split capacitor motor with pure copper windings and internal thermal overload protection, it moves up to 2,760 gallons per hour (1,800 GPH at 10 ft lift). Features a compact vertical switch designed for narrow sump basins, stainless steel impeller, and dual rubber O-ring seals.
Solid Cast Iron Construction: Class 30 cast iron motor housing and base dissipate heat rapidly for longer motor service life. Pure Copper Motor Windings: High-efficiency continuous-duty PSC motor runs cooler and consumes less electricity (4.1 amps full load).
Vertical Float Switch Design: Engineered for narrow sump pits (10" diameter minimum) with positive ON/OFF action that won’t get caught on cords or pit walls. Dual O-Ring Water Tight Seals: Double-sealed motor compartment protects internal electrical windings against water intrusion and moisture.
Standard 1-1/2" NPT Discharge: Features 1-1/2" NPT discharge with a 1-1/4" NPT adapter included in the box for versatile installation compatibility.

Contact usYes. A 1/3 HP cast iron pump moving 1,800 GPH at 10 feet of head is the industry standard for normal to moderately heavy residential groundwater intrusion.
Yes. The motor is rated for continuous duty with oil-cooled housing and thermal overload cutoff that automatically resets when cooled.
It draws only 4.1 Amps at full load on a standard 120V circuit, allowing it to easily share a circuit or run on an auxiliary backup battery inverter.
A check valve is not included in the box and should always be installed on the vertical discharge line above the pump to prevent evacuated water from flowing back into the pit.
Vertical floats travel straight up and down on a guide rod, making them ideal for narrow pits where tethered balls swing and get caught on cords or the basin rim.
