Overview The Little Giant 3-MDQX-SC inline pump is a non-submersible, magnetic-drive unit built for inline circulation and filtration in both saltwater and freshwater aquariums

It can move water up to 1000 GPH at a 3-foot lift, powered by a 115-volt motor, with a six-foot power cord for flexible placement

The magnetic-drive design efficient, compact operation while staying separate from the liquid, reducing leak risk and simplifying maintenance

This pump is intended for inline use and should be installed with the intake below the liquid level

Durability and materials Corrosion-resistant construction for salt solutions and semi-corrosive fluids Glass-filled polypropylene pump head with a ceramic spindle shaft and thrust washers Ceramagnet A ceramic impeller and nitrile O-ring seals for long-lasting performance Thermally protected motor rated for continuous duty CSA to US and Canadian standards Performance and installation 1/15 HP motor delivering up to 1000 GPH at 3 ft lift; max shut-off of about 14 ft Inline, non-submersible design; intake must be below liquid surface; not self-priming 1-inch FNPT suction and 1-inch MNPT discharge for straightforward plumbing 6-foot cord supports flexible routing and safe, plug-in operation Suitable for inline use with canister filters and return lines in mixed tanks Usage tips and safety Plan inline routing to maintain steady flow and avoid air pockets

Verify compatibility with your chosen filtration setup and ensure the intake remains submerged below liquid level as required

Regular checks help maintain consistent performance over time

Maintenance and care Inspect nitrile O-rings and seals during routine checks Clean impeller housing to avoid clogs and maintain flow Keep inline plumbing of air pockets and ensure proper priming in non-self-priming design Quality and certifications Built for continuous operation, this pump's design emphasizes durability, safety, and reliability, backed by CSA certification for North American standards

-world use scenarios Inline return from external filtration to sustain steady water movement in reef or community tanks Pairing with canister filters to manage filtration flow without submerging the motor Can be integrated into sump-to-display return loops for enhanced circulation FAQ Q: What is use case for the Little Giant 3-MDQX-SC inline pump

A: I for inline circulation and filtration in saltwater or freshwater aquariums; install below the liquid level

Q: What are the key durability and installation features

A: Corrosion-resistant materials, thermally protected continuous-duty motor, 1-inch FNPT connections, and a 6-foot cord for flexible inline setups
