This pump is compatible with all our small fountains and operates on 12 volts. The transformer is integrated into the plug and is IP44 rated, meaning it can withstand moist environments. The pump also features an LED light with 6 light points. The light is connected to the pump, so it illuminates when the pump is running. It can be placed both in the water and on dry surfaces, providing illumination for the fountain structure. This creates an impressive effect, especially during spring and autumn evenings when darkness sets in.
