The pump is essentially the heart of the swimming pool's circulation system. Your pool's circulation system comprises the elements of your pool that take water from the pool, filters it, sanitizes it, and returns the water back to the pool. If your pump is not running, the water from your pool is not being properly circulated or filtered. A pool pump consists of three primary components: The Motor, The Impeller, and The Hair and Lint Trap. The motor is electric and uses either 115 or 230 volts and, at full speed, rotates a mechanical shaft at 3450 RPM (revolutions per minute). The impeller, in turn, rotates at the same speed and provides the pressure needed to circulate the water. The hair and lint trap (also referred to as the strainer basket), captures large debris such as leaves that could otherwise clog the pump and reduce or prevent its performance.
Pool pumps come in a wide variety of sizes to best match the unique needs of pools across the world. One way to classify pumps is based on the number of speeds at which it can operate. This is important because the speed of the pump has an incredible impact on the amount of energy it consumes - and, in turn, how much you pay on your electric bill. This is because of the Pump Affinity Law.
This leads to three types of circulation pumps: single speed, two speed, and variable speed. As the name implies, a single speed pump operates at only one speed. These have been the standard type of pool pumps for decades, delivering proven performance and reliability. They are available in a range of designs and sizes (often in terms of horsepower) that match the wide variety of pool and plumbing configurations. Two speed pumps operate at either full speed or half speed - in other words, at 100% or 50%. These pump can offer up to 75% savings in pump energy costs and are also available in variety of designs and sizes. Variable speed pumps operate over a wide range of speeds and can be “dialed-in” to the specific speeds needed for different applications such as basic circulation, heating, spa use, etc. These pumps deliver the ultimate in energy efficiency, with up to 90% savings in pump energy costs. Booster pumps are not needed for basic water circulation but rather deliver the added performance needed to operate pressure cleaners. They operate in conjunction with a circulation pump, boosting the pressure to assure consistent cleaner operation. We can help choose what type
of pump is best for you. As noted, single speed pumps are the most common and have delivered proven performance for years and years. Two speed pumps offer considerable energy savings over single speed pumps, but may require an update to your equipment in order to control the pumps speeds. Variable speed pumps deliver the ultimate in energy efficiency, saving you an incredible amount of money year after year. Although these pumps do cost more up-front, the savings often pay for the added costs in only one or two seasons.
