This pump is compatible with all our small fountains and operates on 12-volt power. The pump is slightly more powerful than the one we recommend for all small fountains and is suitable if the distance between the pump and the fountain is a bit longer. It also suits those who desire a more powerful jet than usual. The transformer is integrated into the plug and is IP44 rated, which means it can withstand moist environments. The light source that this pump has is 6 LED bulbs integrated into the pump, so when the pump is running, the light shines. The cable is a full 8 meters long. We have been selling this pump for over 20 years, which means we have extensive experience of its reliability.
