What size pump motor need for as 23000 gallon pool?

The size of the pump motor needed for a 23,000-gallon pool depends on several factors, including the turnover rate desired, the pool's size and shape, and the type of filtration system used.

For a standard residential pool, a turnover rate of 1.5 to 2 times per day is generally recommended. This means that the entire volume of water in the pool should be circulated through the filter and back into the pool within 12 to 16 hours.

To determine the flow rate required for your pool, multiply the pool's volume by the desired turnover rate in gallons per minute. For a 23,000-gallon pool and a turnover rate of 1.5, the required flow rate would be 23,000 gallons / 12 hours * 60 minutes / hour = 306 gallons per minute (GPM).

Next, you need to consider the head loss in your pool system, which is the resistance to water flow caused by various components such as pipes, fittings, and the filter media. The head loss can be estimated using a head loss calculator or by consulting with a pool professional.

Once you know the required flow rate and head loss, you can use the pump's performance curve to select the appropriate size pump motor. The pump curve shows the relationship between the flow rate and the head produced by the pump at different motor speeds.

For example, if the required flow rate is 306 GPM and the head loss is 10 feet, you would need a pump with a performance curve that shows a flow rate of 306 GPM at a head of 10 feet.

By selecting a pump motor that meets the required flow rate and head for your pool system, you can ensure that your pool water is properly circulated and filtered, helping to keep it clean and clear.
