For our purposes now, we only need to consider three key elements of your pump: the motor, the impeller, and the filter basket. Pool pump technology hasn’t changed much in the past 2,000 years: water is sucked in and pushed out, creating a current that circulates the water in your pool. Though technology has advanced over the past 2,000 years, that’s still roughly how the pump in your pool works. Ctesibius, a Greek inventor and mathematician, is credited with devising a way to siphon water up through one opening and forcibly expel it through another. The principal design for the pump dates back to 200 BC. So what do you do? Knowledge is your greatest asset when shopping for a pool pump, and we have the facts for you. Conversely, if you try to save a few bucks and underestimate your needs, you will find yourself running into a whole new world of problems. In fact, besides being a costly waste of energy, running a pump that’s too strong for your pool can cause a great deal of damage. Choosing a pump isn't as easy as simply buying the biggest, most powerful one you can afford. Whether you're getting a new pool or replacing an old pump, there are many things you need to consider before making your purchase.

The one component responsible for all of this is the pump – the heart of your pool's circulatory system. And if you have a heater, that hot water isn't going to travel around on its own. Circulating water also makes certain that any chemicals you add to sanitize the water get evenly dispersed throughout the entire pool, making them more effective.

When the water circulates, it passes through a filter that removes undesirable particles, helping to keep your pool safe for you to enter. Just as your body has a circulatory system that is vital to your health and well-being, so does your pool.
