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 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.
