D-D Funktion Return Pump
Price range: R2,935.00 through R5,260.00
The D-D Funktion Return Pump range delivers reliable, controllable and energy-efficient return flow for modern marine aquariums. Available in five models from 2,000 to 10,000 l/hr, these pumps offer multiple programmable flow modes, a digital controller and a low-water ‘elephant nose’ intake fitting for stable and dependable sump performance.
D-D Funktion Return Pumps provide advanced, controllable performance for reef aquariums of all sizes. With five models ranging from 2,000 to 10,000 litres per hour, the Funktion series delivers efficient water movement, quiet operation, and fine-grained control through an intuitive external controller.
The pumps feature compact, robust construction and are designed to offer consistent, dependable return flow — essential for sump-based systems, nutrient export, and overall tank stability. Whether used as the main return pump or as part of a more complex circulation strategy, Funktion pumps provide smooth, adjustable flow tailored to the aquarium’s needs.
Programmable Flow Modes
The Funktion controller offers four dynamic operating patterns, enabling precise control over return performance:
- Pump Mode – Smooth, continuous return flow for stable turnover and sump operation
- Pulse Mode – On/off cycling that can help reduce detritus accumulation in plumbing and sumps
- Wave Mode – Timed pulses generate oscillating return flow, increasing surface agitation and oxygenation
- Storm Mode – Intermittent high-output bursts that help flush system dead spots and improve water movement through the sump
“Elephant Nose” Low-Water Intake Adapter
Each Funktion Return Pump includes the specialised “elephant nose” intake fitting, enabling the pump to draw water effectively even when the sump level temporarily drops. This reduces cavitation, prevents air draw, and improves detritus removal at the sump bottom — ensuring stable return flow under real-world operating conditions.

- Digital controller with soft-touch navigation
- Back-lit LCD colour display with adjustable brightness
- Four programmable flow modes (Pump, Pulse, Wave, Storm)
- Adjustable minimum and maximum output limits
