Little Giant submersible utility pump 170 GPH 115V — 1/4-inch MNPT, 18 ft cord, oil-filled motor

The Little Giant 1-AA-18 is a compact 115V submersible pump delivering up to 170 GPH for small water features, cooling, hydroponic and light industrial transfer tasks.

This small, oil-filled motor pump is built for submerged use where reliable, intermittent water movement is needed. It pairs a die-cast aluminum housing and screened inlet with impedance protection to guard the impeller from debris, while the 18-foot cord and 1/4-inch MNPT discharge provide flexible placement and simple plumbing. Rated for intermittent liquid temperatures to 120°F, it suits a variety of settings from residential fountains to machine tool coolant recirculation.

How much flow and pressure can this pump handle?

The 1-AA-18 produces up to 170 gallons per hour at a 1-foot lift and will shut off at about 7 feet of head. Maximum pressure is approximately 3.0 PSI, making it appropriate for low-head applications like small fountains and recirculation loops.

• Rated flow: 170 GPH at 1 ft lift
• Shutoff head: ~7 ft
• Maximum pressure: ~3.0 PSI
• 1/4-inch MNPT threaded discharge for standard fittings

What are the electrical and motor specifications I should know?

This pump runs on standard 115-Volt, 60 Hz power and uses a 1/200 HP motor that draws about 1.1 running amps. The oil-filled motor housing and impedance protection enhance durability and provide safer intermittent operation in submerged environments.

• Voltage: 115 V, 60 Hz
• Power draw: 1.1 running Amps (70 Watts)
• Motor protection: impedance protected, oil-filled housing
• Certifications: CSA listed for USA and Canada

What construction and durability features prevent clogging and wear?

Built with an epoxy-coated die-cast aluminum housing, this pump resists corrosion while the screened inlet reduces debris entry to protect the impeller. The combination of an oil-filled motor chamber and impedance protection helps the unit tolerate intermittent work cycles common in decorative and light industrial use.

• Epoxy-coated die-cast aluminum housing for corrosion resistance
• Screened inlet to minimize debris damage to impeller
• Oil-filled motor housing for thermal and wear protection
• Designed for submersible use only

How easy is it to install and where can I use it?

The pump arrives ready for submersion with an 18-foot power cord and 1/4-inch MNPT discharge that fits common tubing and adapters. It’s suitable for small statuary fountains, water displays, hydroponic setups, air conditioner condensate removal, and machine tool coolant recirculation where intermittent operation is acceptable.

• 18-foot power cord for flexible placement
• 1/4-inch MNPT discharge for easy plumbing connections
• Rated for intermittent liquid temperatures up to 120°F
• Applications: fountains, hydroponics, condensate removal, coolant recirculation

Who is this pump designed for? The Little Giant 1-AA-18 is for homeowners, landscapers, hobbyists and light industrial users who need a small, dependable submersible pump for low-head water movement. Choose this model when you want a compact, affordable solution that is easy to position, resists debris damage, and meets North American certification standards for intermittent submerged applications.
