Ideal to use as a pump for pond fountains, large water features, waterfalls and streams, the Oase Aquarius eco expert 20000 / 12V has been designed by German engineers to give you one of the most energy-efficient yet powerful pumps available on the market today.

With a maximum head height of 6.6m, you're able to create dazzling displays in your pond using the dynamic function control (DFC) switch which will perform a pre-programmed water display. However, with the addition of a Easy Garden Control System (EGC) you can control the flow rate, set timers and choose from 11 different displays all from the free OASE app which can be used from your smartphone or tablet.

The energy efficiency of this pump can't be understated. At peak performance, it has a flow rate of 20000lph whilst only consuming 240 Watts, saving both energy and money when compared to previous models.

The pump can be installed dry or fully submerged, and thanks to this 12V model, the pond will remain safe to swim in. Further, the pump will continue to operate throughout the winter with temperatures as low as -20°C.
