Big Pump Features. Axis pumps offer full control, wireless smart device programming, DC motor quiet operation, and output calibration. Features that have traditionally been reserved for considerably larger and more expensive pumps. Coordinate Feed/Maintenance Modes- Turn all of your AI pumps on or off with a control button on a single pump. Prevent back-siphon- With calibration set, instead of powering off, a pump will continue to run without producing flow, preventing siphoning, which could result in air bubbles when the pump resumes its scheduled operation! With Axis you get exactly what you need, starting with Axis 20 which is perfect for tanks 15 gallons or less.
