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 one of them crumbled. These rubber pieces are not listed on the diagram. I’ve gone to multiple hardware stores and even an auto parts store and searched amazon and have come up empty. I went to the pool store and they said the rubber washer wasn’t something pentair aells. Has anyone come across this and if so, where did you find a replacement? I’ve attached the diagram for my pump and added a red arrow to show where these things go.

The flat washer is a motor slinger and the shaped part is the motor shaft seal behind the slinger.

Note that the Motor Shaft Seal is not the same as the Pump Shaft Seal.

For added protection, a slinger located in front of the main motor shaft seal assists in slinging water away from the shaft opening in the flange.

What the heck. I browsed through sooooo many pentair parts on Amazon. Thanks! But what about that other piece?

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...

Omg, that “v-ring” is $38 if I follow the link in that thread.

I do love that you found the part at Leslie’s and the guy at my nearest Leslie’s couldn’t find it.

The flat part is called a slinger.

Any flat rubber washer with the correct ID will work.

So I don’t need the other thicker “v-ring”? Just the flat washer?
 
I see where you mention doing this cleaning out because of noise thing going on but just going by the picture of the pump it would seem to me that the shaft seal had failed some time ago and water has been getting in the bearing which if your at this point do not close up the motor because you'll be back to tearing into the pump when the noise is intolerable or the motor simply dies.

You don't really need either piece.

The bearings are probably bad.

There were multiple references to the part in the referenced thread that were low cost, but the sellers might only sell to businesses wholesale.

Also, there are several sizes and yours might be a different size.

I bought from this seller on eBay due to the availability. Paid 11.00 (best offer) plus tax shipped.

I did find a few online stores that were selling for around 7.00 shipped but did not have any in stock so I went ahead and paid the four dollar premium to get it quicker.

Following up to close out this thread.

New seal was delivered today. Glad it was a rubber seal and not moms good china as box was flattened out like a pancake.

Seal is an exact match for the original one.

For the price it gives me a better level of comfort than reusing the original one. Not only was the old one cracked but it was apparently dried out as the replacement one is a lot more pliable.

Replacement seal is on the left of both pictures.

How to read the reference of a v-ring seal?

Example:
VA20-NBR
Where
VA = gasket shape
20 = shaft diameter on which gasket will be mounted (approximate)
NBR = material

How to read the suffixes of a v-ring? (type of rubber)

FOR OILS AND HYDROCARBONS
NBR = Nitrile = Butadiene rubber - Acrylonitrile
from -30°C to +110°C
FPM = Viton = Fluorinated Rubber
from -20°C to +200°C

S - Section V-Rings - Viton Rubber S-Section V rings have a conical rear face (needs more space than an A section V-ring) and unlike oil seals don't have a rigid steel shell, V-rings are made completely of rubber and therefore can be stretched over fittings, flanges, bearings, couplings, keys etc.

They comprise of a single molded body and conical lip.

The 'V'-Ring is mounted on and rotates with the shaft, with the lip sealing against the housing or bearing, the body being held in position by its tight grip around the shaft also serving to seal against the shaft.

Benefits: Flexible shaft range, inexpensive, durable, accommodates misalignment, deflects greases, oils, liquids, grit, sand etc.

So I should just rebuild it? I found one thread that describes the process and seems pretty straightforward.

Bearings are bad, can the motor be rebuilt?
 
Versatile V-Rings for Shaft Seal Applications
A V-Ring is a solid axial shaft seal that uses centrifugal slinger action to prevent dirt, moisture, and other unwanted contaminants from entering an oil seal or the housing while simultaneously keeping lubricants inside. The V-Ring rotates with the shaft and holds itself in position by its flexible fit on the shaft. Sealing is induced by the contact between the seal lip and the counterface. V-rings work well on their own but are mostly used in combination with other seals like radial shaft seals, and sometimes they are also used as pre-sealing material for bearings.

Advantages of V-Rings
V-Rings are very versatile and offer many advantages.

They help in reducing the wear and extending the service life of oil seals, shafts, and bearings.
Since they are made of rubber and have an elastic nature, they can be easily stretched over flanges or other components for easy installation with minimal machine disassembly. Just ascertain the shaft is clean and dry, administer a bit of lubricant to the V-ring lip and slide the v-ring down until the elastic lip touches the counterface. The lip presses against the counterface with minute pressure and friction.
V-rings offer very little torque drag and heat built up and do not require costly countersurface preparation.
Functions nicely in dry applications, on spinning shafts and oscillating shafts, and at high velocities above 3000 FPM.
Wide tolerations permit a single v-ring to fit numerous shaft sizes and to solve significant shaft misalignment and eccentricity in the shaft. Its durability assures a prolonged work life and that it won’t be damaged while installation.

Question though, do I have to buy a whole brand new pump or can I just buy a motor?
