Pump Shaft Seal Installation

[gridert]

I just had a leaking shaft seal replaced on a two year old motor and the pump went from whisper quiet to annoyingly loud. I pulled the pump out to inspect the impeller and noticed this sloppy bead of sealant around the seal plate, makes me wonder about the repair. Is that a normal part of the fix? Thanks in advance.

Looks like someone overdid the silicone caulk, but as long as none of it got on the mating faces it may not be the cause of seal failure. Definitely not a professional job

Welcome to TFP gridert

There isn't really a way to know what caused it but that sure does look like someone who was in there was sloppy and that's never good.

There should be no caulk around that seal at all.

Thank you all. I now believe the "sealant" is in fact silicone grease put on a little too thick during seal replacement and the fact that the bearings are corroded and making noise are the result of the shaft seal leaking for an extended time.

There shouldn't be any grease on the seal either it will drastically reduce the life of the mechanical seal.
