Sizing the Pump for Your Swimming Pool
- Circular Pools: Diameter (ft.) x Diameter (ft.) x Average Depth (ft.) x 5.9 = Total pool capacity in gallons.
- Oval Pools: Length (ft.) x Width (ft.) x Average Depth (ft.) x 6.7 = Total pool capacity in gallons.
- Rectangular Pools: Length (ft.) x Width (ft.) x Average Depth (ft.)
Likewise, people ask, what is the flow rate of a 1.5 HP pool pump?
For each 1.5 inch intake line, the maximum flow into the pump will be 42 gallons per minute (GPM).
In this manner, can a pool pump be too powerful?
The more powerful your pool pump is—the more horsepower it has—the faster it will turn the water over, which means you can run it less often and for shorter periods of time. But this is also dependent upon the size of your filter and the filtration system’s pipes. A too-powerful pump can be too much for a small filter.
How many gallons per minute does a 3 HP pool pump?
Pool Pump Operating Costs
| Pump Size | GPM (varies with plumbing) | Cost/7 Days |
|---|---|---|
| 1.0 HP | 60 | $10.08 |
| 1.5 HP | 68 | $15.12 |
| 2.0 HP | 76 | $20.16 |
| 3.0 HP | 85 | $30.24 |
How much HP pump do I need?
Horsepower theoretically required for pumping water equals the gallons per minute multiplied by the head in feet, and divided by 4.000 For power recommended, divide by 2000 instead of 4000.
What is the GPM of my pool pump?
Most pool pump specifications are expressed in gallons per minute (GPM). So, to convert from GPH to GPM, divide your GPH by 60 minutes – 2531 GPH / 60 = 42.2 GPM.
How do I calculate gallons in my pool?
Length times width gives the surface area of the pool. Multiplying that by the depth gives the volume in cubic meters. If you’d like to find the pool volume in gallons, multiply your results by 7.5, as there are 7.5 gallons for each cubic foot.
Who makes Pentair pumps?

How does Pentair freeze protection work?
The system detects all devices that have Freeze Protection ON, and activates the device to stop the pipes from freezing. If freeze protec- tion is only applied to one body of water. Note: If the pool or spa is running a schedule or operated manually, this will override freeze protection.
What size pump do I need for a 30000 gallon pool?
Pool gallonage x 2 (the recommended number of cycles in a day) ÷ daily hourly run time ÷ 60 (minutes in an hour). So, for a 30,000-gallon pool that runs continuously (24-hours), the formula is: 30,000 x 2 ÷ 24 ÷ 60 = 41.6 or rounded up it’s a 42 GPM minimum flow rate.
What is a variable speed pool pump?
Variable speed pool pumps are becoming a more popular option among pool owners. They allow you to run your pump at different speeds. Unlike a single-speed pump, you can set the system to run on high when you are filtering chemicals or on low when your pool needs to be cleaned during peak energy use hours.
What happens if your pool pump is too small?
If your pool filter is too small for the pump, there will be additional strain on the pump motor as it tries to push water through and encounters resistance at the filter. This will eventually burn out the pump motor and your filtration will also be compromised.
What size pump do I need for a 24 above ground pool?
For pools up to 24 Ft Round, use a 1 HP pool pump. For pools over 24 Ft Round, we recommend using a 1.5 HP pool pump.
How many gallons per minute does a 2 HP pool pump?
Is a higher HP pool pump better?
A pool pump that is larger than needed has a more powerful motor and circulates water at a higher flow rate. This uses significantly more energy to pump the same amount of water and puts additional stress on your pipes and filter, meaning you’ll need to replace them sooner.
Is 1 HP pool pump enough?
Let’s start with an unpopular and incredible statement: A typical size residential pool can be circulated effectively with a 1 HP pump.
What size pump do I need for a 15000 gallon pool?
A 15,000-gallon pool needs about 20 GPM output if we want to run it 24 hours per day.
How long do pool pumps last?
Can you oversize a pool pump?
Dangers of having an Oversized Pool Pump
If your pool pump is too large then you can end up with a number of issues that can be avoided with having the right pool pump size. For Sand Filters, having an oversized pool pump can cause channeling because of the water pressure.
