D-D Funktion DC Return Pumps

The D-D Funktion DC Return Pump range combines power, efficiency, and control to deliver reliable circulation for reef, marine, and freshwater aquariums. With models from 2000 to 10000 L/H, Funktion return pumps are designed for both small and large systems, providing quiet operation, flexible installation, and advanced safety features.

Each pump is equipped with a digital controller featuring multiple flow modes, soft-start operation, adjustable power settings, and feed mode for quick flow reduction during feeding or maintenance. Run-dry detection and automatic shutdown protect both the pump and your aquarium, while low-voltage sine-wave technology ensures minimal noise, low heat, and maximum energy efficiency.

The pumps can be installed submerged in a sump or externally (on larger models), and come supplied with multiple fittings for both flexible hose and rigid pipe connections. Built with wear-resistant ceramic shafts and bearings, the Funktion return pumps are engineered for long-lasting performance in demanding aquarium environments.
