External Pump advantages
External pumps are larger in size as well as in power capacity when we compare them with submersible pumps. As submersible pump are more preferred choice for the garden owners because of their compact size and very easy setup process. However, when it comes to the pump for larger size koi ponds we would recommend you to go for external pumps as they many advantages when t require to pump large amount of water.
1) External pumps are more energy efficient
When we compare the energy efficiency of the external pumps, they are usually more power savers when compared with submersible one. The savings will be unnoticeable when we check for smaller ponds. However, for large ponds with capacity above 8000 gallons of water, you may notice the difference. Hence, if you have pond that large we would recommend you to go with the external pumps.
2) High Flow Rates Head Height Potential
When it comes to flow rate of the water, external pumps don’t have upper limit. Submersible pumps usually have capacity flow rate of maximum 10,000 gallons, so if the water volume increases, the power require to pump that water increases, which submersible pump cannot do due to their limited capabilities.
3) Head Height Potential
Talking about the head height issue, it is not viable for the external pumps, as they usually sit above the water level on the ground. Hence, this things leads to higher flow rate. There are various external pumps available in the market, which have horse-power (HP) rating in place of gallons per hour (GPH), so they are able to circulate tons of gallons of water per hour. Which make their flow rate limitless.
4) Easy to Maintenance, Clean & Manage
The major benefit of having external pond pump is they ae very easy to maintain, manage and clean. Since, these up usually sits on the ground, so you don’t have to worry about going inside pond and take out pump to clean it. In comparison to submersible pump, external one don’t clog easily as they don’t have to contend with debris and particles inside water. Hence, you are looking for easy cleanable, manageable pump go for external pumps.
So, we can summarize benefits of external pump as
- High capacity over 8,000 US gallons
- Good Heavy fish stocked ponds (Koi)
- Easier cleaning and maintenance
How to choose the best external pond pump (Guide)
When it comes to choosing perfect external pump, we recommend you to go with regular centrifugal motor driven pump over asynchronous pumps available. However, we will give you detailed guide about how to choose the best external pump.
1) Energy efficiency rating
As we mentioned above one of the main benefits of having external pump is its energy efficiency over circulation large gallons of water. But while buying the external pump we should we should look at its energy efficiency rating. Some of the pump available with built in technology, which optimizes energy usage. So this thing is very important to look before buying external pumps.
2) Head height vs Flow rate
External pumps are available in two varieties; one with high max head height and strong flow and other with low max head height and strong flow. The selection of choice is totally depend upon your requirement. Pumps with low max head height will prover higher circulating water, but it would not be efficient with the large ponds. When we consider high max head height pumps they will have good circulating rate, and they are very good for lifting water from heights for large ponds. If you want to have power a filter system, then low max head height and strong flow pumps will be better option, where circulation is primary thing.
3) Variable speed control
There some brands, which provide flow rate control feature in there pumps, so you have option to control flow rate and height head. You just have to set the switch in ‘high’ and ‘low’ modes of speed and provide you full control of flow and energy usage. This feature is not that necessary, but it may be an add-on to save the water flow and maximise energy savings. We would recommend you to have full speed water circulation in hot summer days for better aeration and lower speed circulation when fish require less food and there is lower waste to filter. In case your pump do not have speed control option, then we can use ball valve control the water flow.
4) 115 Volt or 230 Volt Pump
There is another thing we must consider is the voltage capacity i.e. 115V or230V. The lower power usually have 115V power and powerful one 230V. Practically speaking when we use 230 V pump for large reservoirs then it will be more cost beneficial and for small ponds of 6000 – 8000 gallons 115 V is sufficient. We would recommend 230 V would be better option in any case as running 230V on small reservoirs with lower GPH will be same as running 115V at full GPH.
5) Flooded suction or Self-priming Pump
Now we come to main thing there two types of external pumps available they are flooded suction centrifugal ponds and self-priming centrifugal pumps. Flooded suction pump are usually cheaper in comparison then self-priming pumps and there is requirement of surrounding their impeller motor with adequate water. This water requirement makes most external pumps to be installed at below or at level of pond line. This makes water circulation easy by entering without resistance in pump chamber. The second class of pumps is self-priming ones and they have unique feature to create suction that mixes air and water, while that not the same with non-self-priming which would stop functioning in case of excess air. Self-priming pumps mixes air and water to create fluid with pumping properties, which smoothens pumping. The major advantage of the self-priming over flooded one is that, they pump water from closer distance and doesn’t need hole below the water line to work effectively. But one thing to consider that self-priming pumps are much more expensive than flooded suction pumps. Hence, it is totally depends upon your pond design and size, which pump is suitable for your need
How to Install a Pond Pump?
When it comes to installing of the external pump, it is very simple process. The first thing we need to sort out the bottom of the pond, and it should be levelled well for proper circulation of the water then we provide two water way air hole inside it, one for suction and other one for drawing out water inside the pond. Regular thing we must check is the water level inside the pond, less water level will be harmful for pumps as well as the fish inside it. In first after filling up pond install you pump and switch it on. Now connect your pump to filter and most important thing please don’t add fish immediately after switching on the pump, wait for a one day at least and make sure everything is working fine and properly. Then afterwards proceed further.
In our list, the top pick is Evolution ESS Self Priming Pump, which is incredibly easy to install, very durable, and the perfect power for both small and large ponds. Along with these features it is very energy efficient self-priming external water pump, that will save your pocket in the long run.
If you don’t consider Evolution ESS then go with more sizing options for smaller or larger ponds is Helix Koi External Pump. It is also very durable and sturdy built, but it cannot by par the effective ness of Evolution as it is not self-priming and very expensive in cost also. There are other like Max pro, laguna( for only fountain effect) and alpine hybrid pump you can go for.
