How To Select Above Ground Pool Pumps

One of the advantages of above ground pools is that the pumps and filters are sold as one unit. These pump/filter systems are usually attached to a single base and are much more economical than an individual pump and filter. Here we'll cover the basics of both pumps and filters for above ground pools.

Step by Step

Step 1

Sizing above ground pool pumps is much simpler than their inground counterparts. Above ground pool pumps are generally below the waterline thereby gravity fed, with minimal plumbing between it and its suction ports. The simplicity the pool’s plumbing allows you to size the pump by pool size alone (most times.)

Step 2

Round Pools: The chart shows the normal manufacturer pump sizing recommendations for pool sizes. The horsepower overlaps on the “tweener” sized pools 15’ is a small to medium, and 27’ is medium to large.

Ranges:
  • ¾ Horsepower: 8’ to 15’ Round
  • 1 Horsepower: 15’ to 24’ Round
  • 1-1/2 Horsepower: 24’ to 36’ Round

Step 3

Oval Pools: Similar to the round pools, the horsepower recommendations overlap for some models. If your pool falls in one of these overlap areas, then consider how much swimmer traffic you expect. Light to moderately used pools, choose the lower HP, for higher swimmer loads, choose the step up.

Ranges:
  • ¾ Horsepower: 12’ X 17’ to 12’ X 24’
  • 1 Horsepower: 12’ X 24’ to 15’ X 27’
  • 1-1/2 Horsepower: 15’ X 27’ to 18’ X 33’

Step 4

Reasons to step up horsepower: Longer than standard plumbing lines and/or pool accessories may require you to make the jump to the next highest horsepower to ensure proper flow rates. Common causes for larger pumps
  • Suction line from the skimmer to pump is longer than 15-feet
  • You’re planning to use a suction cleaner, e.g. the Hayward Navigator, The Pool Cleaner, and Kreepy Krauly
  • Adding solar panels, especially ones mounted on roofs or fences increase the strain on the pump, requiring extra HP oomph

We would recommend a 2HP above ground pool pump for your 18'x40' pool. Something like the Jacuzzi SLR9 model would be ideal.

Courtney - Step 3 of the guide actually lists your pool size and the recommended pump horsepower in the text, and on the picture graph.

Hello Lisa - A 1.5HP pump should be more than enough for a 12'x24' above ground pool. You could go with a 2HP pump as long as your filter can handle the additional flow.

Hi I am building an above ground swimming pool measuring 640x370x150 what size of pump and filter do I need plz. Thanks

InyoPools Product Specialist  Posted: 2/18/2019 

We'd be glad to assist you. Are those measurements in centimeters or inches?
 Reply

 Posted: 2/18/2019 

Hi good afternoon the measurements are in thanks
 Reply

InyoPools Product Specialist  Posted: 2/18/2019 

If those are inches, it translates to a pool that is roughly 53'x31'x12.5'. That would be over 100,000 gallons. Does this sound accurate?

Hi sorry was my mistake the measurements are CM thanks

I'd recommend a 1HP filter and a 100 square foot cartridge filter. Something like the Hayward model CC10092S would be sufficient.

Hello Gina - We'd recommend a 21" sand filter and 1.5HP pump. Something like the Hayward model S210T93S would be sufficient.

Right now we are running a one horse pump The water starts to Gallup if we don't watch it closely we have to shdut it off and let the water calm down . My question is what size pump should I be running I already have a sand filter . Will a 1/2 hp be enough ?

Great information to help me replace my pump system!

Hello Mike - Yes, Jacuzzi Laser Sand Filters are compatible with other pump brands. You may not be able to use the type of hose that has union nuts on the end. You'll probably need a hose that clamps onto the adapter fittings.

Hello Gwen - We'd recommend the Hayward EC50AC for a 28' above ground pool.

We just purchased a home that has 28' round above ground pool. Looking to replace the sand filter. They had their own makeshift pvc tubing for the lines and it we have tried everything to fix it - not working. We are looking at the DE filters - Which Hayward Perflex Extended-Cycle D.E would be our best bet?

Hello. Are Jacuzzi Laser Sand Filters compatible with other pumps (ie; Hayward)? TIA

Hello Herbert - A 2HP pump is a little overkill for a 24' round pool. I would go with a 1.5HP 2-speed pump.

Hello Craig - We'd recommend a 1HP pump and 18" sand filter for your 15'x26'x52" pool. Something like the Hayward S180T92S would be sufficient.

We are getting a 24' round x 52" deep pool. Is a 2 speed 2 hp motor a good pump to use for his pool?? Also it's a cartridge filter pump

Hello Ruth - We'd recommend Pureline Pure Pro XL 3/4HP pump. The model number is PL1500. You'll probably need adapters for the ports since the Coleman pools use smaller hoses. An adapter that should work is part number 4564.

Hello Jess - We'd recommend something like the Hayward EC40AC for a 21' above ground pool.

I have a 16'x16' round Coleman above ground pool. The pump that came with it doesn't seem to filter the water fast enough & the water seems a little murky most of the time, even after treating it. We want to get a bigger pump this year, can you suggest what I should look for and will it be compatible with the hoses, etc we already have or will we have to buy adaptive parts tll?

Hello Brad - Most of our 24' pool owners prefer a 1-1/2HP pump. We would recommend a sand filter that is 20" or larger.

Hello Pam - A 20" sand filter would be sufficient for a 24' pool with a 1HP pump. Something like a Hayward S210T would be a good option.

Anonymous (AG Salt pool) - Here are links to Above Ground Pool Pump and Filter and Above Ground Pool Sanitizers that you should consider for converting your above ground pool to a upgraded pump and filter system with a salt chlorine generator.

Carrie S Newbold - It depends on the size of your AG pool. If it's a smaller pool. less than 9,000 gallons, I would recommend a Hayward VL Series Sand Filter System. If your pool is between 9,000 and 13,000 gallons, I would recommend a Hayward Pump & Filter S166T Filter W/ 1 HP Matrix Pump.
