img of Elastomer Bellows Dry Mechanical Seal for Pool Pump

Elastomer Bellows Dry Mechanical Seal for Pool Pump

This elastomer bellows dry mechanical seal is a direct OEM replacement designed specifically for residential and commercial swimming pool pumps. It features a fully vulcanized EPDM bellows that provides superior flexibility and chemical resistance against chlorinated and brominated water.


Unlike conventional spring-loaded seals, the bellows design eliminates the risk of \"hang-up\" on the shaft due to debris or mineral buildup — making it ideal for older pumps with worn shafts or plastic impeller housings. The carbon rotating face runs smoothly against a ceramic stationary seat, delivering reliable sealing under intermittent start-stop cycles typical in pool filtration systems.


Whether you are servicing a Hayward Super Pump, Pentair WhisperFlo, or an aftermarket pool pump, this seal offers a cost-effective drop-in solution without compromising performance.
