Extend the Life of Your Hot Tub Pump Seal
Having a good hot tub seal is important to any hot tub pump since a leaking pump seal could mean bad news for you and your spa. Like any other equipment your hot tub pump seal can wear out over time requiring to be replaced, but choosing the right seal for your hot tub will help it last longer. There are also some operational and installation tips that can help extend the life of your seal.
Choosing the Correct Hot Tub Pump Seal
In the past, Premium hot tub pump seals have been made of Buna elastomers, a phenolic (plastic) carbon and ceramic mating ring. These materials work well for a seal when small amounts of chlorine are long diluted before they reach the pump seal; but with applications today like ozonators, salt chlorine generators, and hydrogen peroxide based chemicals, the Premium seals are not the best option as these elements destroy the Buna elastomer and the primary ring.
US Seal, the manufacturer of the pump shaft seals we carry at Hot Tub Warehouse, has made newer applications that work better with ozone, salt generators, and peroxide based chemicals. These hot tub pump seals a made to better withstand the elements that come with these sanitizer systems.
Seals in the US Seal Ozone/ Salt line are made with Viton elastomers a resin filled carbon ring with ceramic of a superior grade. These materials have been found to withstand the chemical output of ozone and salt, allowing for a longer life of the seal and reducing pump and motor issues.
Choosing the right hot tub pump seal, and following the operational and installation tips above will help you get the longest life possible out of your hot tub pump seal.
