What Size Pump Do I Need for My Above Ground Pool?
Over Ground Pool: For upon |You know that the pump is the main thing for any swimming pool system. If your pool comprises a saltwater system, then it becomes more significant to have your pump sized correctly. There is a misconception that purchasing the largest pool pump means you’ll have found enough circulation for your pool. Though this is a good idea, it can lead to high electrical usage and might be very expensive.
We have arranged a simple step-by-step guide to assist you in calculating what size pump is perfect for your above-ground pool. This will make certain that the pump is the most efficient size for your pool system. It will just take a few minutes to work by these effective steps and these steps will help you get the perfect size for the above-ground pool. The steps are discussed below sequentially:
Calculate the pool volume:
We first have to determine how much water is in your pool. This will help you figure out how many gallons of water ought to be circulated within the 8 hours and provide you with a conception of the required turnover rate.
The rectangular pool will be length (ft) x width x average depth x 7.48, the oval pool will be ½ length (ft) x ½ width x average depth x 7.48 x 3.14, and the round pool will be radius (ft) x radius x average depth x 7.48 x 3.14. If you want to use a calculator to determine how much water is in your pool, you have the option to use the Pentair pool volume calculator.
Minimum flow rate:
After having determined how many gallons of water are there in your pool, you have to convert this into the rating per minute gallon. We shall assume that you would like to achieve two complete turnovers per day that are recommended for the system of saltwater.
If you like to operate the pump less you will require enhancing chlorine output on the chlorine generator. The methods of calculating the minimum flow rate are given below:
16,500 gallons x 2 turnovers a day = 33,000 gallons per day
33,000 ÷ 24 hours = 1,375 gallons per hour
1,375 ÷ 60 minutes = 22.91 gallons per minute–GPM

Maximum flow rate:
Now you have the minimum flow rate needed to fill two turnovers a day you have to figure out the maximum flow rate. The length and diameter of the plumbing, pool instrument, and extra features in your plumbing system can limit the maximum flow rate.
There are a couple of determining topics that can demonstrate the maximum flow rate for your pump system. All plumbing can be rated for maximum flow rate and basically, this is how much pressure it can withstand. The plumbing in your pump system gets the recommended maximum flow rates.
2.5” Plumbing = 120 GPM
2” Plumbing = 73 GPM
1.5” Plumbing = 43 GPM
Flow rate range:
Now, that you know how to figure out the minimum and maximum flow rate for your pool system, you can also determine the flow rate range. We have drawn the example to help you determine the flow rate range:
A saltwater pool along with 16,500 gallons of water from your pool on a 24-hour cycle that can complete two turnovers per day will need at least a minimum flow rate of 22.91 GPM.
If we assume that we have 1.5” plumbing supplying our spa, this can limit up to 43 GPM. You’re using a 3.1 square feet filter that gets a maximum of 60 GPM, and you will take the lower of the two rates and determine that our maximum flow rate will be 60 GPM.
Final range and TDH:
Now you’ve completed your pool pump sizing and become able to buy a pool pump that will work safely and efficiently along with your pool system. We hope that our example of the sizing pool pump can be determined by following these:
22.5-60 GPM or FRT (Flow Rate Range)
50-60 TDH or Ft of Head
When you’re going to purchase a pool pump in every single model, you will have found a chart to determine the best Horsepower for your needed Feet of Head or FRT (Flow Rate range).
Conclusion
Considering the above discussion, we can say that every step of the above discussion must be needed to have the right size pump for your above-ground pool. We think you’ve enjoyed knowing the information and will be able to purchase the right one according to your requirements.
