The water in a swimming pool needs to be filtered and re-circulated periodically, in order for it to remain healthy. Pool pumps filter and then re-circulate water contained inside the pool. In a way, they are analogous to kidneys and liver in human body. This article offers a crisp guide to swimming pool pumps.
Both domestic as well as public pools need to be kept clean. This is done by passing the water through hair and lint filters and then introducing cleaned water, back to the pool. These pumps are high power consuming devices with a wattage that can exceed 2000 Watts for commercial swimming pool pumps. This can be particularity troublesome for commercial swimming pools whose pumps have to operate 24 hours a day during summer months. As a result, pumps that are powered by solar energy, like the ‘Savior-Solar Pump and Filter’ are gaining popularity. Their cost can reach thousands of dollars, even for small pumps. However, once invested in, these can operate at almost negligible costs.
Above ground swimming pool pumps operate by gravity feeding the water to a pump that is placed above the water level of the pool. The filtering systems in above ground pumps can be of three types: sand, cartridge and diatomaceous. Sand filters work well with largest sized impurities while diatomaceous filters work well at filtering impurities of smallest size. The latter can become a victim of loss of water flow with increased usage.
An ideal pool pump should consume less power and have integrated thermal control. Pumps that have variable motor speed offer greater opportunities for power saving. Also, these should be controllable such that the filtering and recycling speed can be reduced when the pool is empty and increased when it is full. The outer body should be made of non- corrosive and water-proof material. The power cord should be long enough; ideally, a 6 feet long power cord serves well. If you are buying your pump from outside of your home country, make sure to check voltage specifications. A pump rated at 110 A.C. will not function in a country with 220 A.C. as the standard voltage of power supply. For safety reasons, the on/off switch should be protected in a rear mounting arrangement. Lastly, the strainer basket should be of industrial size and should allow discharge in various orientations like vertical, horizontal and angled. Companies like Pentair, Intex, Polaris, Savior and Hayward make some of the best swimming pool pumps.
Each pool pump is covered under manufacturer’s warranty. Swimming pool pumps can be tricky for a first time buyer. Make sure to research well before you go to a store and compare quotes from several dealers before buying.
