US Seal PS-200 Pool Pump Motor Shaft Seal

Key Fit

• High-Performance Motor Shaft Seal (PS-200) – Designed to prevent water leaks between the pump wet end and motor

• Carbon & Ceramic Seal Faces – Provides reliable sealing and durability under heat, pressure, and continuous operation

• Viton Elastomers for Chemical Resistance – Resists pool chemicals and elevated temperatures better than standard rubber seals

• Protects Motor & Bearings – Prevents water intrusion that can lead to corrosion, bearing failure, and motor damage

• Replace During Motor or Pump Service – Should always be replaced when rebuilding a pump or installing a new motor

• Fits Many Pool & Spa Pumps – Compatible with a wide range of pump models; verify fit by manufacturer and model

• Critical Leak-Prevention Component – A small part that plays a major role in pump reliability and lifespan

A leaking pool pump doesn’t just waste water—it can quickly lead to motor failure if left unchecked. The US Seal PS-200 Motor Shaft Seal is a high-performance replacement shaft seal designed to stop leaks at the motor shaft, protecting your pump motor and restoring reliable operation.

This seal is engineered for pool and spa pump applications, using durable materials that resist heat, chemicals, and wear commonly found in chlorinated pool systems. It’s a trusted choice for technicians and pool owners performing pump repairs the right way.

Why a Quality Motor Shaft Seal Matters

The shaft seal is one of the most critical components inside a pool pump. When it fails, water leaks directly toward the motor bearings, often resulting in expensive motor damage.

Using a high-quality motor shaft seal matters because it helps:

• Prevent water leaks at the motor shaft

• Protect pump motor bearings from corrosion

• Extend the life of your pool pump motor

• Restore proper pump operation after seal failure

The PS-200 is designed to handle the heat, pressure, and chemistry of real-world pool systems.

How the US Seal PS-200 Works

The PS-200 uses a carbon rotating face and ceramic stationary seat, paired with Viton® elastomers for superior chemical and heat resistance. Together, these components create a tight mechanical seal around the motor shaft, preventing water from passing through while allowing smooth rotation.

This design ensures consistent sealing performance even under high operating temperatures and continuous run cycles.

Common Signs You Need a Shaft Seal Replacement

The PS-200 motor shaft seal is typically replaced when you notice:

• Water leaking between the pump and motor

• Rust or corrosion on the motor flange

• Loud or failing motor bearings caused by water intrusion

• Seal replacement during motor or impeller service

Replacing the shaft seal during pump repairs is essential to prevent repeat failures.

Designed for Pool Pump Applications

This seal is specifically positioned as a pool equipment replacement part and is commonly used in a wide range of pool and spa pumps that accept PS-200–style seals. It is suitable for residential and light commercial pool systems.

Always confirm seal compatibility with your specific pump model before installation.

Built for Chemical & Heat Resistance

Pool water environments are harsh. The PS-200’s Viton components resist degradation from chlorine, bromine, salt systems, and heat generated by pump motors. This makes it a reliable option for modern pool systems operating under demanding conditions.

Installation Notes

Proper installation is critical for shaft seal performance. Always clean the seal plate and mating surfaces thoroughly, avoid touching the polished seal faces, and ensure correct orientation during assembly.

If you’re replacing a motor, the shaft seal should always be replaced at the same time.
