Spas are one of the best things that we can include in our homes. Spas not only rejuvenate our body but mind and soul. However, your spa is of no use without a spa pump. Spa pumps are the heart of any spa. The principle on which a spa works is that water is pulled through sources and then passes through a heater before emerging out of the jets and allows you to take a hot rejuvenating bath in your tub. And without spa pumps the water cannot be moved and hence cannot be heated.
The spa pump comprises of two parts i.e. the wet end that contains the impeller, which is the key moving part of a spa pump and a motor that turns the impeller. Spa pumps draw water from suction ports such as skimmers and main drains and the water comes out through the jets.
Spa pumps as already mentioned pull water through the filter and lets the water come out through the jets in 50/50 air to water ratio. And there are certain spa pumps that are specifically designed for circulation of water as well. However the key function of a spa pump is warming the water up by pumping the water through the heaters. Another important role that a spa pump plays is it keeps the water clean while circulating. No matter how advanced your spa tub is or how many jets you have in it, if the water is not pumped at the required pressure there is no use of a hot tub!
