How do I know the flow rate of my pool pump?
In other words, how long should it take to move the entire contents of your swimming pool through the filter. Divide the pool gallonage by the turnover rate to determine the minimum flow rate per hour. Divide that number by 60 to determine the minimum flow rate per minute.
How do you calculate gallons per minute on a pool pump?
- Surface Area.
- Gallons of Water.
- aD = Average Depth.
- The Horse Power of Inground Pool Pumps.
- Ideal Gallons Per Hour (GPH) = Gallons of pool water / 8.
- Ideal GPM = GPH / 60.
- Now that you have the ideal GPM you need to figure out the Feet of head of your pump.
How many GPM is a 1.5 HP pool pump?
Pool Pump Operating Costs
| Pump Size | GPM (varies with plumbing) | Cost/Hour |
|---|---|---|
| 1.0 HP | 60 | $0.06 |
| 1.5 HP | 68 | $0.09 |
| 2.0 HP | 76 | $0.12 |
| 3.0 HP | 85 | $0.18 |
How many gpm does a 2 HP pool pump?
73 gallons per minute
The maximum flow into the pump will be 73 gallons per minute for each intake line.
How to calculate the flow rate of a pool pump?
Once you have the approximate number of gallons of water in your pool, we have to figure our minimum flow rate for the pump, using a Gallons Per Minute (GPM) calculation. GPM takes into account your pool size and the number of “turnovers” you need per day (your turnover rate).
How to calculate how much water is in a pool?
We first need to determine how many gallons of water are in your pool. This will help us figure out how much water needs to be circulated in an 8 hour period and give us an idea of the required turnover rate. Rectangular pool = length (ft) x width x average depth x 7.48 Oval pool = ½ length (ft) x ½ width x average depth x 3.14 x 7.48
How to find the right pool pump for your pool?
Evaluate your pool and find out the correct pump size for your pool. The result is a properly sized pump that delivers maximum efficiency and longevity. Answer all questions to the best of your knowledge.
How many gallons per minute does a 1.5 hp pool pump?
Click to see full answer. Likewise, how many gallons per minute does a 1.5 HP pool pump? For each 2.0 inch intake line, the maximum flow into the pump will be 73 gallons per minute (GPM). For each 1.5 inch intake line, the maximum flow into the pump will be 42 gallons per minute (GPM).
Once you have the approximate number of gallons of water in your pool, we have to figure our minimum flow rate for the pump, using a Gallons Per Minute (GPM) calculation. GPM takes into account your pool size and the number of “turnovers” you need per day (your turnover rate).

What is the minimum flow rate for a salt water pool?
Now that you know how to calculate the minimum and maximum flow rates for your pool system you can determine the flow rate range. If we use the example above we can determine the following: A salt water pool with 16,200 gallons of water on a 24 hour cycle that completes 2 turnovers per day will require a minimum flow rate of 22.5 GPM.
What should I consider when choosing a pool pump?
Another factor that needs to be considered when you’re looking at aspects of your system that limits flow, is your pool filter. The type of filter (cartridge, DE or sand) and the size will determine the amount of flow they can handle. See the chart below for a better illustration of maximum flow rates as well as best flow rates.
