Description
xThe Danner Supreme Aqua-Mag 350 is a durable, oil-free magnetic-drive water pump engineered for continuous aquarium circulation, delivering up to 350 GPH for saltwater or freshwater systems.
Built to run quietly day and night, the Supreme Aqua-Mag 350 combines a magnetically driven impeller with an epoxy-encased power housing so it can be used submerged inside the tank or installed in-line within plumbing. Its fish-safe, oil-free design and energy-efficient operation make it suitable for reef tanks, freshwater displays, sumps, and return lines. The unit also includes a reusable debris pre-filter and meets UL/ETL safety certifications.
How much flow and power does this pump provide?
The Aqua-Mag 350 moves up to 350 gallons per hour while drawing a maximum of 35 watts (0.6 amps) on standard 120V / 60Hz power. That balance of flow and efficiency makes it a practical choice for moderate-sized systems that need steady circulation without high electrical cost.
- Maximum flow: 350 GPH
- Power consumption: up to 35 W / 0.6 A
- Voltage/frequency: 120 V / 60 Hz
- Recommended tank size: up to 40 gallons
Can I use this pump submerged and outside the tank?
Yes — the pump is designed for both submerged and in-line use, offering flexible placement options. When submerged it quietly circulates water; when installed in-line it can serve as a return pump or part of a filtration loop, keeping mechanical noise and vibration away from the display.
- Submersible operation for hidden, quiet placement
- In-line installation compatibility for sumps or plumbing runs
- 1/2" FPT inlet and 1/2" MPT outlet for standard fittings
- 10' cord for flexible positioning
What parts and protections help it run reliably in aquariums?
The pump uses a magnetic impeller assembly that separates the drive from the wet area, reducing wear and preventing oil contamination. The electrical components are sealed in an epoxy-encased housing for long-term protection, and the included reusable pre-filter captures particles to minimize clogging.
- Magnetically coupled impeller for oil-free, fish-safe operation
- Epoxy-encased power unit to resist moisture and corrosion
- Reusable debris pre-filter to extend service intervals
- Meets UL/ETL standards for safety and reliability
How large is the pump and what plumbing fits it?
The compact footprint lets you hide the pump in tight spaces or inside equipment cabinets. Standard 1/2" inlet and outlet threads accept common adapters and fittings, simplifying connections to tubing, hoses, or PVC plumbing.
- Dimensions: 5.0" L x 3.8" W x 4.2" H
- Inlet: 1/2" female pipe thread (FPT)
- Outlet: 1/2" male pipe thread (MPT)
- Cord length: 10' for flexible reach to power
Who is this for: Aquarium hobbyists who need a dependable, energy-conscious water pump for tanks up to about 40 gallons — ideal for reef keepers, freshwater enthusiasts, and anyone who wants a quiet, oil-free circulation solution that can be used inside the tank or tucked away in plumbing. The Danner Supreme Aqua-Mag 350 is also well suited for setups requiring standard plumbing connections and long cord reach.
