A water pump is the most important component of a hot tub system. Basically, a hot tub is an open tank filled with hot circulating water. Pumps help in water circulation and push the water through filters and heaters.
Hot tub pumps mainly comprise of two components namely, the wet end that moves the water and the electric motor that can also be called as the dry end. Motors come in a wide range of horsepower ratings. They are normally 115 volt or 230 volt. Some hot tub pumps have expensive hi-tech seals between motors and impellers, which help in preventing and eliminating water leakage.
They also have a much higher capacity of water flow than the standard pumps. Due to the high capacity of the pump there is no danger of the hot tub getting over-heated in the summer months. It also means that the hot tub has crystal clear water that is always ready to use. Along with all these benefits, the best part of high quality water pumps is that they are relatively silent. They are all rubber mounted, which eliminates any hum due to vibrations.
