Pentair Whisperflow - Motor friction washer?

There is a lot of great info on this forum but I could not find an answer to the following:

I'm replacing the seals on a 2HP Whisperflow Pump which is straightforward however during disassembly we found on the motor side of the seal plate the remains of some kind of friction washer/gasket on the motor shaft. Since this is on the motor side it does not appear on the Pentair parts lists but after trawling through AO Smith parts for the motor I can't find any references to this washer/gasket at all. There was not much of it left when I split the seal plate but its definitely some kind of gasket a little thicker than copy paper and black almost like wet n dry paper. Any advice on a replacement much appreciated.

Welcome to TFP.

You have any pics of what you found?

@JamesW may have ideas.

The gasket basically disintegrated as I separated the seal plate so no pics. It certainly looks like the water slingers as suggested however if I add the water slinger it looks like it might prevent the seal from fully seating into the motor housing?

Thanks James, I'm familiar with the process but not familiar with the water slinger. Actually in both videos the motor housing looks to be different?

There is only one seal and it goes in the seal plate.

The motors are all square flange motors.

The slinger should not interfere with the seal.

You really don't need the water slinger, but it will mean that there is a larger risk of water getting into the motor if you do have a seal leak.

Get a good seal to reduce the risk of a leak.
