What size sand pump for a 22×52 pool is a common question among pool owners and installers. The size of the sand pump is crucial for ensuring the proper filtration of your pool water, which is essential for maintaining a clean and healthy swimming environment. In this article, we will discuss the factors to consider when choosing the right sand pump size for your 22×52 pool and provide some recommendations.
The first factor to consider when selecting a sand pump for your 22×52 pool is the pool’s turnover rate. The turnover rate is the amount of water that must be filtered through the pool’s system each day to maintain cleanliness. A general rule of thumb is that the pool should have a turnover rate of at least 8 to 10 times per day. To calculate the required flow rate for your pool, multiply the pool’s volume by the desired turnover rate.
For a 22×52 pool, the volume is approximately 33,840 gallons (128,000 liters). If you want an 8 to 10 times turnover rate, you would need a pump with a flow rate of 272,320 to 338,400 gallons per day (1,030,400 to 1,280,000 liters per day). This translates to a flow rate of about 11,400 to 14,000 gallons per hour (43,000 to 53,333 liters per hour).
Next, you need to consider the head pressure of your pool system. Head pressure is the resistance that the pump must overcome to move water through the pool’s plumbing and equipment. The higher the head pressure, the more powerful the pump must be. To determine the head pressure, measure the total height of the plumbing from the pump to the highest point in the pool system, including any elbows, tees, or other fittings that may increase resistance.
Once you have the flow rate and head pressure, you can begin to look for a sand pump that meets these specifications. Most pool stores and online retailers offer a wide range of sand pumps, and you can find models with flow rates ranging from 1,200 to 50,000 gallons per hour. When choosing a pump, look for one with a flow rate that falls within the range of 11,400 to 14,000 gallons per hour for your 22×52 pool.
Another important factor to consider is the pump’s motor size. The motor size should be adequate to handle the pump’s flow rate and head pressure. A good rule of thumb is to choose a pump with a motor size that is 1.5 to 2 times the pump’s flow rate in gallons per hour. For a pump with a flow rate of 11,400 to 14,000 gallons per hour, a motor size of 17 to 23 horsepower would be appropriate.
In conclusion, when selecting a sand pump for a 22×52 pool, it is essential to consider the pool’s turnover rate, head pressure, and the pump’s flow rate and motor size. By choosing a pump that meets these specifications, you can ensure that your pool water remains clean and clear, providing a safe and enjoyable swimming experience for you and your family.
