How to Replace the Shaft Seal on a Pentair SuperFlo Pump

If your Pentair SuperFlo pump is leaking around the motor shaft, it’s time to replace the shaft seal. This essential maintenance task ensures your pool pump operates efficiently, preventing further damage and costly repairs. In this article, we’ll provide a detailed guide on replacing the shaft seal, helping you restore your pump’s performance. Whether you’re a DIY enthusiast or considering professional help, this guide is your go-to resource.

What is a Shaft Seal and Why is it Important?

The shaft seal is a small but critical component of your Pentair SuperFlo pump. It prevents water from leaking along the motor shaft, ensuring the motor remains dry and operational. Without a functioning shaft seal, water leakage can damage the motor, leading to expensive repairs or replacements

.At PoolRX LLC, we understand the importance of maintaining your pool equipment. That’s why we offer expert services using industry-leading tools like Leaktronics for accurate leak detection.

Signs Your Pentair SuperFlo Pump Needs a Shaft Seal Replacement

How do you know it’s time to replace the shaft seal? Look out for these signs:

• Water dripping from the motor area.
• Visible cracks or wear on the seal plate.
• Reduced efficiency in your pool pump.
• Unusual noises during operation.

Ignoring these signs can lead to severe damage to your pump’s motor and other components.

Tools and Materials Needed for the Job

Before starting, gather these essential tools and materials:

• Screwdrivers (Flathead and Phillips)
• Wrench or socket set
• Small picks or pick set
• Replacement shaft seal (e.g., 200 seal for SuperFlo)
• Lubricant (e.g., Magic Lube)
• Clean rags or towels

Having these items ready ensures a smooth replacement process.

How to Prepare Your Pump for Shaft Seal Replacement

Preparation is key to successful maintenance:

1. Turn off power at the breaker to ensure safety.
2. Drain water from the pump by removing drain plugs.
3. Clean the exterior of the pump to prevent debris from entering during disassembly.

Taking these steps minimizes risks and sets you up for success.

Step-by-Step Guide to Replacing the Shaft Seal

Follow these steps carefully:

1. Disassemble the Pump

• Remove the seal plate by undoing four bolts securing it to the wet end.
• Take out the diffuser by removing quarter-inch bolts.
• Unscrew the impeller using a reverse-thread screw (clockwise).

2. Remove the Old Shaft Seal

• Detach the seal plate from the motor by removing its bolts.
• Push out the old shaft seal using a screwdriver or similar tool.

3. Install the New Shaft Seal

• Clean all components thoroughly, ensuring no debris remains.
• Insert the ceramic side of the new shaft seal into the seal plate.
• Position the rubber side facing the impeller.

4. Reassemble and Test

• Reattach all components in reverse order: impeller, diffuser, wet end, and motor.
• Prime your pump by filling it with water before turning it on.
• Check for leaks around the motor shaft.

This process restores your pump’s efficiency while preventing further leaks.
