Pumps are literally the heart of any water feature. The function of continuously circulating water and providing enough aeration creates a sustainable and stable ecosystem. Whatever water feature you own in your backyard or anywhere for that matter requires a pump to maintain the water in them. If you are deciding to get one for your pond, which you should, you may have a lot of questions in your mind. How do submersible pumps for Ponds work? Why is it necessary? Are there any limitations? How large should the pump be? So on and so forth. Don’t worry, we are here to help!
Do not forget to read the entire article to answer all your questions and make an informed decision about submersible pumps for your Pond.
Why are submersible pond pumps necessary?
There are a large variety of pumps for Ponds available but submersible ones have a few advantages over these. The first one being, as submersible ponds are always in the water, there is no priming required. If you use an external pump, utmost care must be taken to make sure that there is water in the pipes before switching on the pump so as to prevent the pump from sucking in plain air and burning.
The second advantage of submersible pumps is that they are very easy to store as they are hidden in the pond. Whereas, for an external pump, extra effort is needed to hide the pump and blend it in the landscaping in such a way that it is still accessible when required.
How do they work?
If we neatly break down the process, submersible pond pumps run on a fairly basic principle. To drive an impeller, there is an electric motor. When this impeller turns, the water is drawn or sucked in from one side of the pump and is expelled or thrown out of the other. The simple logic is that – the larger the impeller, the more is the quantity of the water pumped. That being said, if you want a larger impeller, it requires a more powerful electric motor as well. This will in turn use more electricity.
How large should a submersible pond pump be?
Whether you intend to have a submersible pond pump or not, you still need to figure out how much water your pond can hold so that you can buy an appropriately sized pump. Ideally your pump should be able to pump the entire water in your pond in about 2 hours. This situation applies when the pond is working with no extra strain due to gravity or pipe fittings. For example, if you are pumping water up the hill for a waterfall, you will need to consider the additional pressure required. Based on this, you can choose the size of your pump to eliminate any complications in the future.
Are there any limitations of submersible pumps?
If you need to place your submersible pump in a limited space or clearance, it may be difficult to fit an entire pump in there. In situations like these, choosing an intake pipe which is smaller than the pump itself would be a wise idea. But having an intake pipe will again lead to an external pump.
The best example of such a situation would be a skimmer. If there is any floating debris on your pond, to capture it, you need to get the water flowing through the skimmer. There has to be some kind of pump inside the skimmer to draw the water in. On the other hand if the skimmer is large enough, you can place a submersible pump inside the skimmer which will eliminate the need to have an external pump.
We hope that, through this article, we told you everything that you need to know about submersible pumps for your ponds. This is important as, without a pump, the water in your pond will not circulate and start becoming very messy.
The worst case scenario is when there is not enough oxygen in your pond which will lead to your pond plants dying and an unhealthy growth environment for your fishes. So get a submersible pond pump to enjoy all the benefits of having a backyard pond without having to troubleshoot problems every now and then!
