Your fountain pump is the most crucial part of your fountain, as it is responsible for circulating water, creating sound, and preventing the growth of algae by adding oxygen to the water. The pump you choose is very important for the performance and overall life of your fountain, which is why you need to understand the basics of pump selection before making a choice. The next few paragraphs will help you understand what to look for in a fountain and how to choose the one that is best for you.
If you have a large outdoor fountain, the water fountain pump that you choose will require a more powerful water flow. Essentially, you will want a flow of one hundred gallons per hour for every inch of width of the stream of water your fountain produces. In other words, if your fountain has a five inch water stream, you will want a pump that delivers five hundred gallons of water every hour. Most pumps have a switch to make the flow larger or smaller so that you can tailor it until you get the right result with minimal splash. Large pond waterfalls may require pumps that can handle 2,000 gallons of water or more per hour.
If you have a smaller indoor fountain, you will find that the requirements are much lower. In fact, too much water flow in an indoor fountain will cause splashing and can damage carpets, walls, furniture, and other items. Ideally, you will want about forty five gallons per water for the average tabletop fountain. Flow adjustment switches can also be found on these smaller fountain pumps, ensuring that you are able to prevent splashing without needing to give up the pressure needed for your fountain to perform properly.
For medium sized fountains, the average gallon per hour output is between one and two hundred. This is true for both indoor and outdoor fountains. Choosing the right water fountain pumps can keep your fountain running perfectly for a great deal of time without risking damage from overuse or from splashing.
In all, the pump you choose will perhaps be the most important choice that you make. Ensuring that your fountain pumps enough water to meet its purpose without pumping so much as to create splashing is the best way to ensure a long pump life. Learning which pump is best for your fountain can seem tricky, but once you understand how they work, the process is actually surprisingly simple.
