Why use a submersible pump for your garden project? | How to choose the best submersible pump |

A submersible pump is ideal for outdoor water projects such as fountains, waterfalls, spouting ornaments, ponds, and water gardens. Corrosion resistant pumps are available for use in salt water. Using a submersible pump in a Koi or other fish pond allows you to retain more fish, and maximizes the health of your aquatic plants. Also, a submersible pump is the most economical way to circulate water in your pond or other water feature. It is placed directly in the pond and usually must remain underwater in order to operate. An important feature of a submersible pump is that it is quiet and virtually free of distracting noise. It can also be used to drain your pond when necessary. Be careful to read and follow the instructions of the manufacturer if you install the submersible pump yourself, because there are many variables to be considered. A regular outdoor electric outlet using an all weather extension cord is satisfactory to power the pump, or a submersible pump can work off a generator when plugging in is impractical. A magnetic drive pump, which avoids the use of coolants, eliminates the possibility of pump seals rupturing and spilling oil coolant into the water. There are numerous sizes and types of pumps, therefore it is advisable to seek some guidance in choosing a submersible pump for your project. Some factors to consider are:

Choosing the best submersible pump for your unique needs will save significant time and money in energy costs and down time. It is prudent to consider future needs when determining your usage requirements. Do you need a submersible pump because you are going to install a pond on your property or purchase a herd of dairy cows? Maybe you work in the wastewater industry and need to select a submersible pump suitable for that particular application. Installing a pump that is larger than you need is a waste, since the life of a pump is determined as much by starts and stops as it is run time. It is important to understand how the motor works on a submersible pump to properly evaluate its effectiveness. The best pump is equipped with a motor that works below its load limit. You never want your submersible pump to do more work than its motor can handle. The full load amperage or FLA rating of the pump is vital. This rating is one of the best indicators of the amount of work the motor shaft is able to accomplish. The type of impeller used on a submersible pump must also be taken into consideration. It is important to know the pump head correctly. The head is a measure of how much pressure a submersible pump can develop. Head is measured from the surface of the water or other material to be pumped. Usually a submersible pump box will provide the maximum head information, but often pump flow rates at different heads or heights is not indicated. A centrifugal submersible pump usually pumps less water as the head is increased. At maximum head, the flow from any pump is zero. |

Before installing a submersible pump, the pump should be wired, immersed in a container of water and operated. Taking these measures insures that the pump is in proper running order. The type and the size of drop pipe used for submersible pump installation is dependent upon a number of factors: The depth to the water and pumping level, the amount of pressure that the submersible pump can attain, the allowable friction loss in the drop pipe, and the weight of the submersible pump. Follow the steps listed below to install your submersible pump:

Every submersible pump is manufactured and designed to operate within certain parameters. As the pump works against rising pressure, which is converted into feet of head, the pumping capacity falls. Alternately, as head falls, pumping capacity rises. The pumping capacity versus the total head form the engineering curve of a submersible pump. If a submersible pump is operating to the left of its curve or is undersized, there is too much head against the pump. Conversely, if a submersible pump is operating to the right of its curve or is oversized, there is too little head against the pump. It is, therefore, very important to achieve balance in order to secure optimal functioning of a pump. Listed below are some recommendations to follow when sizing a submersible pump:
