A DC return pump running quietly in the cabinet means one less thing competing with your living room for attention, and AquaIllumination's Axis line covers that job across three sizes. All three pair with AI's ecosystem for app-based monitoring and control.
Why a Centrifugal DC Return Pump
A centrifugal design paired with DC motor control gives you quiet operation and efficient power use for the always-on job of a return pump — running continuously in a stand or cabinet where noise and heat both matter more than in an open-air powerhead application.
Choosing a Size
- Axis 20 — the smallest in AquaIllumination's Axis return pump line, built for tanks 15 gallons or less, with performance that punches above its compact size.
- Axis 40 — the mid-size model, stepping up flow capacity from the Axis 20 while keeping the same quiet DC operation.
- Axis 90 — the largest in the line, built for bigger systems that still want quiet DC operation over a louder AC alternative.
Setup Tips
- Size for your sump's return plumbing and head height, not just tank volume alone.
- Use app-based monitoring to track pump status alongside your other AI equipment.
- Consider Axis specifically where noise matters — living rooms, bedrooms, or anywhere a loud AC pump would be a real drawback.
The AI Axis line is available at Marine Concept Supply across all sizes — order online or pick up at our shop in Wheeling, IL. Shop Axis 20, Axis 40, or Axis 90, and browse more aquarium return pumps.
