Danner 12545 Magnetic Drive Pump Impeller Cover - black

Solved issue with noise & flow...simple & less than new pump assembly..restored flow..

Decided to try for my old model 3 pondmaster pump, it centered amature and runs again. Think 2017 purchase. This maybe the last revival, but for the small price , ok.

Perfect fit and function.

I would rate this cover 4.5 stars if I could but I'll go conservative. I have replace these covers on pumps in the past and their longevity is pretty good. Better than the impellers which last they themselves last a pretty good lick (2-3 years or so running 365 days a year at about 10 hours per day). Since only 1 manufacture makes this product, it is difficult to compare to anything else. However, given the longevity and price to replace, it is a fair deal.

I didn't want to replace my 15 year old pump so... Great fit!!

The original impeller cover on my pump had the center support broken off, pump still worked but was very noisy. This cover quieted my pump and it works like new again. (Supreme Pondmaster 500 GPH pump.)

Exactly the part needed to bring new life back to a <4 yr old Mag Drive. On a new impeller cover the area for the impeller's ceramic shaft bushing to sit into is Pentagon shaped, after the pump has been in operation for a while, the recess become rounded out and causes the impeller to hang up or "knock" when spinning. Good idea to keep a spare on hand so that when you're servicing or cleaning your pump - you can replace this part if it is no longer supporting the impeller bushing correctly & bring it back into alignment.

Danner pump impeller cover I received had a crack in it making it useless. The attached picture shows two Danner 750 pumps with cracked pump impeller covers. The two pumps are from a third party that uses their pumps. The cracks are just to the side of the upper threaded output part of the cover. The three products were ordered between 06-27-2024 and 7-10-2024.
