Benefits & What Makes It Different
Buna-N & Ceramic Construction

Stainless Steel Compression Spring
Maintains uniform face-to-face tension under variable hydraulic pressures and continuous daily run cycles.
Compatibility
- Residential pool and spa pumps requiring a 5/8-inch shaft seal
- Standard chlorinated, brominated, and mineral-treated freshwater systems
- Compatible with standard Buna-N general service pump rebuild specifications
When To Use This
Pro Tip
Never touch the polished carbon or ceramic faces with bare fingers; skin oils create localized hot spots that lead to premature seal failure. Wipe surfaces clean with isopropyl alcohol before final assembly.
Common Questions & Instructions
What pool pump setups use the U.S. Seal PS1000?
The PS1000 is engineered for standard residential freshwater pool and spa pumps with a 5/8-inch motor shaft running conventional chlorine or bromine sanitation.
When should the PS1000 pump shaft seal be replaced?
Install a new PS1000 assembly whenever separating the motor from the seal plate, replacing an impeller, or if moisture appears at the bracket weep hole.
Can the PS1000 mechanical seal be installed on saltwater pools?
While functional in mild conditions, standard Buna-N seals like the PS1000 degrade faster in high-salt or ozone environments, where Viton-based seals are preferred.
