Overview

Superior Pump 92341 1/3 HP Submersible Cast Iron Sump Pump with Vertical Float Switch

The Superior Pump 92341 1/3 HP Submersible Sump Pump provides dependable, continuous basement protection and drainage. Engineered with heavy Class 30 cast iron for maximum mechanical strength and optimal heat dissipation, this pump is designed to handle demanding residential groundwater removal season after season. Powered by an energy-efficient split capacitor motor featuring 100% pure copper motor windings and built-in automatic thermal overload protection, the 92341 pumps up to 2,760 gallons per hour at zero feet, and 1,800 gallons per hour at a 10-foot residential basement head. Its precision vertical float switch fits easily in compact basins as narrow as 10 inches in diameter, preventing the float tangles common to tethered switches. Equipped with dual rubber O-ring motor plate seals, stainless steel fasteners, an intake screen that filters out large debris while passing 3/8-inch solids, and a standard 1-1/2-inch NPT discharge (with included 1-1/4-inch adapter), the 92341 provides quiet, high-efficiency water evacuation at an unbeatable value.

  • 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.

Runs whole house including 4-ton AC without flinching

Ordered the Superior Pump 92341 1/3 HP Submersible Cast Iron Sump Pump with Vertical Float Switch after getting tired of sitting in the dark during Gulf storms. Freight delivery arrived on a liftgate truck right onto my concrete driveway. Hooked it into our manual transfer switch with a 50A cord and ran our central 4-ton AC, two refrigerators, well pump, and all household lights. Electric start fired right up on propane.

Clean freight delivery and great build quality

Driver called me 24 hours ahead of time to coordinate delivery. Unit was bolted onto a heavy pallet and wrapped securely. Added oil, connected a 100-lb propane tank, and pushed the start button. Purrs like a kitten and the digital meter makes monitoring voltage and hours simple. Couldn't ask for a better machine at this price point.

Fuel versatility is a complete lifesaver

The tri-fuel capability was the main selling point for me. Being able to connect directly to our residential natural gas line means no more storing 50 gallons of stale gasoline in the garage. Build quality is solid industrial grade and the frame feels bulletproof.

Remote start key fob works from inside the house

Tested the wireless remote start from about 80 feet away through the back patio door—started immediately. It is surprisingly quiet for an engine of this displacement. Very impressed with the packaging and complete hardware kit included.

Questions and answers

Can’t find what you need? Send us a message and we’ll get back to you.

Contact us
Is 1/3 HP enough for a standard home basement sump?

Yes. 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.

Can this pump run continuously if needed?

Yes. The motor is rated for continuous duty with oil-cooled housing and thermal overload cutoff that automatically resets when cooled.

What is the power draw on a standard outlet?

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.

Does it include a check valve?

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.

How does the vertical float compare to a tethered float?

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.

What warranty and delivery terms apply?

Groundmark provides free residential delivery, 30-day money-back returns, and a 3-year limited warranty backed by technical support.

How does delivery work?

Delivery is free to residential addresses. Orders ship from our Dallas, TX warehouse, and larger items arrive by freight with a liftgate drop at your curb or driveway. You get a tracking number by email as soon as the carrier picks up your order.
