D-D The Aquarium Solution has added a new range of DC return pumps to its own-brand equipment offering. Named Funktion, the range comprises five models capable of maximum flow rates of 2000-10000lph, and are controllable via a wired multi-function LCD backlit controller with color display.
Functionality comes in the form of 30-100% flow control, with Feed Mode, and near silent running via Sine Wave technology. But included also is run-dry detection with automatic shutdown and four flow modes – Pump, Wave, Pulse, and Storm, all of which can also be adjusted by the user to create their ideal flow ramp and rhythm.
The consistency and controllability of the Pulse Function is such that this return pump can produce pulsing currents via your return, just as an in-tank wave pump would, yet still maintain constant height on the standpipe inside the weir, and quiet running. Once set there is no need for extra adjustment of a ball valve or gate valve, but the return of water to the tank pulses, giving even more water movement in the tank.
An “elephant nose” suction attachment is included to prevent vortexing in shallow water, but it will have the added benefit of scavenging any detritus that could otherwise collect in the pump chamber, as well as any residues from dosing. A standard suction cage is also provided, along with quick couple unions for connection to both flexible and rigid pipes.
We all need maximum energy efficiency from our equipment these days, and a quick comparison of liters per hour per watt of energy used reveals that the 6500, (48-watt) model delivers 135 liters per hour per watt of energy, with three of the other models not far behind at 125lph/w. This places them quite a way ahead of some leading DC return pump models in terms of energy efficiency, and being Sine Wave, if the others aren’t, they are likely to be quieter too.
UK pricing is £94.99 for the 2000 model, £109.99 for the 3500, £124.99 for the 5000, £139.99 for the 6500, and £169.99 for the 10000 model.
