US Seal PS-1000 Motor Shaft Seal – High-Performance Pump Seal
Stop Pump Leaks and Protect Your Motor
A leaking pool pump isn’t just a nuisance—it’s a serious risk to your motor and overall circulation system. The US Seal PS-1000 Motor Shaft Seal is a high-performance replacement pump seal engineered to stop leaks, safeguard motor bearings, and keep your pool pump running at peak efficiency.
When a shaft seal wears out, water seeps into the motor, causing overheating, corrosion, and expensive repairs. Replacing it with the PS-1000 restores a tight, watertight barrier, protecting your equipment and saving you money over time.

Why Shaft Seals Are Essential
Your pool pump’s shaft seal may be small, but it does big work: it keeps water away from the motor while allowing the impeller to spin freely. Without a working seal, you risk:
-
Bearing failure due to water intrusion
-
Motor overheating and burning out
-
Electrical shorts or system shutdowns
-
Poor circulation and water quality
-
Costly repairs or early pump replacement
The US Seal PS-1000 prevents these issues, ensuring safe and efficient operation.
When to Replace Your Shaft Seal
Shaft seals don’t last forever, especially under tough pool conditions. Replace yours if you notice:
-
Water dripping between the pump housing and motor
-
Rust or corrosion on the motor shaft
-
Grinding or squealing noises from the pump
-
Reduced flow or pressure in your system
-
A burnt smell caused by overheating bearings
Catching these warning signs early and replacing the seal protects your entire pump system.
