喷泉水泵是一种用于喷泉设备的发动机，是以电动机或涡轮机为动力来对水份进行运送。它是用于生产喷泉回流系统的节点，用于把入口安装的水流量提升到喷泉的高度，也是安装喷泉景观系统非常重要的一个元素。
喷泉水泵一般还分为光水泵和柴油机水泵，光水泵是一种电动机驱动的水泵，在工作中对电动机要求相对较低，省电易于操作，但不利于增加水流量和压力，只能用于一些低高度、较小范围的水池;而柴油机型水泵无需电源，可以直接利用柴油机驱动，可以增加喷泉的高度和提高水流量，更适合于安装在水池和大型喷泉系统中。
此外，喷泉水泵 not only provides energy to spray the fountain, but also plays a vital role in improving the ecological environment. On the one hand, the fountain can inject more oxygen into the water body, increase the biological diversity in the water body, and reduce the deficiency of oxygen in the water caused by overcrowding of fish and shellfish; on the other hand, it can timely discharge the residual and organic waste in the water body, limit the reproductive growth of unhelpful organisms in the water body, and prevent the appearance of "pollutive water".
In conclusion, the fountain pump is an indispensable component of building a green environment. It not only has the advantages of energy-saving and beautiful decoration, but also plays an irreplaceable active role in improving water resources and ecological environment. It is expected that, with the further development of this kind of equipment, the fountain can be used in water resources protection, lake engineering, landscape engineering and other areas, to contribute to the development of water ecology and environmental protection.
