The infamous Jandy e-pump squeal

[troymeboy]

Another winter means tolerating this hideous noise from my Jandy e-pump again. I’ve had this thing at least 5 years now. It seems to be a common problem and yet I can’t find anyone who has definitively solved it. Whenever it gets to be below about 40 degrees, this monster starts the same shrill cry. It comes from the back of motor like it’s got something to do with the rear bearing. It never becomes anything more than a major nuisance as the pump works flawlessly at all times.

Somebody make it stop!!!!!

Three possible causes.
1) Bearings.
2) Pump Shaft Seal.
3) Motor Shaft Seal.

The black rubber is the motor shaft seal.

Changing Intelliflo shaft seal and.....

I am in the process of changing the shaft seal on my 2011 Intelliflo 011018 pump. I purchased the Pentair go kit and have gotten things apart and started to do the clean up and reassembly when I noticed that the rubber seal in between the shaft seal and front bearing has a slight crack in it...

Trouble locating or finding or even identifying rubber gasket and ring

So I took apart my pentair Superflo VS pump, to replace the dried out o-rings, and also to clean it, because it’s been loud. I have a kit that has most the pieces I need. However, when I removed the motor plate and exposed the motor drive (??), there were two rubber pieces that are so dried that...

Thanks James. If it helps, 1poolman1 let me know the following when I posted on the same issue a while back:

Your pump is one the ones that had a Century (owned by Regal Beloit) V-Green 2.7 motor (or at least model of the V-Green made for Jandy, they would never say).

Yes, I remember discussing this exactly 2 years ago on January 21 2023.

Try replacing the seal with a good seal.

If it's not the seal, it is probably the bearings.

Jandy ePump noise when under 40 degrees

Greetings TFPers! So I've had this Jandy variable speed pump for about 4-5 years now. Every winter I suffer through the hideous noise. It doesn't seem to harm anything other than eardrums and my sanity. Anyone living where temps drop below 40F that owns one of these pumps knows what I'm talking...

Wouldn’t a bad seal result in leaking water, especially after several years?

I’ve seen another thread where Jandy replaced the whole pump and motor and the problem still resurfaced with the replacement.

It’s hard to believe that nobody has identified what the issue is for sure. I hate to replace bearing or seal and end up trading the noise for something worse so I continue to endure. Haha

Two surfaces rubbing against each other can create a squeal.

It won't necessarily leak.

In any case, I think that these are most likely.

1) Bearings.
2) Pump Shaft Seal.
3) Motor Shaft Seal.

The motor-shaft seal is not the one that prevents water leaks, that is the pump-shaft seal. Motor shaft-seal is there to protect the motor if the pump-shaft seal leaks, though it seldom really does unless the water leak is caught and repaired quickly.
The motor shaft actually rubs against its seal and that can cause a squeal. It takes dismantling the pump to do what is described in the troubleshooting guide as a fix, so guess how many people actually do that or want to pay to have it done.
