I owned this pump for a little over three years, along with the upgraded stainless steel head. It worked great up until my last brew day on October 3rd. Turned the pump on, it wasn't spinning. Did a quick disassembly, nothing was blocking the impeller though it did seem to spin a bit rough. Removed the rest of the housing, spun the magnetic ring and it was very rough. I managed to loosen it up enough that it'd spin when powered on, albeit it with a very loud screeching noise. I ran it for a 20 minute whirlpool, then again to transfer into my fermenter. Took the head back apart and gave it a good cleaning as I always do and that was that. Fast forward to yesterday. I decided to try and lubricate it, as I had never done that before and it's something often recommended to do periodically. Looked all over, couldn't find anywhere to drop some oil. I posted on here and another vendor, ask well as shoot an email to Keg King directly (no reply yet) asking if/how the pump could be lubricated. Turns out it can't! So knowing that my pump is most likely useless, I decided to take it apart. Once apart, I quickly discovered that the bearing in the picture is crunchy. It's beyond shot. I suppose if somebody were so inclined (and more mechanically apt) they could probably replace the bearing. But that somebody ain't me.Anyway, it was a great pump while it lasted. It consistently receives great reviews, and for the price compared to other name brand pumps, it's almost unbeatable. I'm still tempted to buy another once since I already have the upgraded stainless steel head. I just wish there was a way to lubricate the bearings easily without breaking the seal (and presumably any warranty).
