The new Koralia models are now available.
Although the pumps are very similar, the changes are important. The new pump uses a new rotor made of anisotropic ferrite (a magnet with a preferred direction of orientation) that provides improved performance, low power consumption and less vibration. In the new koralia, the starting of the pump is smoother, so Hydor could eliminate the hydrofoils allowing a gain of about 10% in flow performance versus the old model.
The pump uses an updated shaft in stainless steel AISI 316 instead of bushings. The shaft material has been extensively tested for long life without experiencing any wear and or corrosion (especially in salty environments). The propellor encounters less resistance in the new Koralia model. The water passes through the pump much more easiliy providing enhanced performance.
A ring for more robust hydrodynamics has been added to the front grille. The new grille is 100% compatible with the previous version. Even the grille of the upper chamber was reinforced to withstand the stresses over the years due to the use of timed controls.
In case of use without a timer
It’s possible to remove the thin drain cover of the rotor segments and this will enhance the water flow by 15%.
The new Koralia pumps provide super performance: only 5w for 5600 litres per hour.
With the new koralia in the aquarium you can circulate 3200, 4400 0r 5600 litres of smooth and powerful flow.
The wide flow outlet and characteristics produced by the pumps are those which have made Hydor Koralia the leader on the world market in the segment of wave pumps/
Even maintenance is easier now as the pump is made in only 3 pieces.
