2 HP Pool Pumps
Most swimming pool pumps come in one of four sizes: ¾ HP, 1 HP, 1.5 HP, and 2 HP. HP refers to the amount of horsepower a pump uses, and swimming pool pumps that use 2 HP provide the most amount of horsepower needed out of any other model. They are better suited for larger swimming pools or pools with more features.
As mentioned, if you have a large or commercial swimming pool, or one with ample water features, choose a 1.5 or 2 HP swimming pool pump. The pool pump is the key piece of equipment in your system for quality water, so choosing the right size with the correct horsepower is essential. Calculate the amount of horsepower your pool pump needs to circulate the water below.
Here’s how to calculate the amount of pool pump horsepower. Take this example and fill in your own swimming pool’s gallons. And remember, the pool volume (gallons) multiplied by two equals daily gallons required for a 12 hour turn.
EX: For a pool that holds 15,000 gallons of water.
15,000 gallons x 2 turnovers/day= 30,000 gallons/day
Circulate 30,000 gallons of water every 24 hours. How many gallons per minute, or GPM, is this?
30,000 gallons/ 24 hours = 1,250 gallons/hour
1,250 gallons per hour/ 60 minutes = 20.8 gallons per minute
A 15,000 gallon swimming pool needs about 20 GPM output if you want to run it 24 hours a day. Use this example and plug in your own pool’s gallons to determine if a swimming pool pump that runs on 2 HP fits your needs. A swimming pool pump that uses 2 HP is also ideal for commercial pools. These pumps provide the power needed to circulate a large body of water.
