What are the Different Types of Pump Seals?
It's definitely worthwhile to use the "ozone/salt" seal. The regular seals will wear out and leak. The silicon carbide seals are the best, but usually too expensive to be worthwhile in most cases.[1][2]
Basic Seals
Basic seals have Buna Elastomers, a Phenolic (Plastic) Primary Ring and a Ceramic Seat. Theses are junk due to the primary ring composition.
Ozone/Salt Seals
"Ozone/salt" seals have Viton Elastomers, a Carbon Primary Ring and a Polished Ceramic Seat. These are acceptable.
Best Quality Seals
The best seals have Viton Elastomers, a Silicon Carbide Primary Ring and a Silicon Carbide Seat.
