Danner Manufacturing, Inc., Supreme Aqua-Mag 1200 GPH Magnetic Drive Water Pumps for Aquarium, 02712

I’ve used this pumps for years and they have always been quiet and reliable. The one I purchased before this one was March of 2023. These,pumps have a 5 year warranty. I searched dannermand there site actually has a phone number that people answer. Their customer service rep told me to send him a screen shot of the Amazon order. He also wanted a few photos of the pump and the tag that was on the pump body. Within hours of the info being sent they emailed me for my address and will send me another pump. The service is excellent. I will use the pump as a spare to swap out. Thanks Danner.

This pump runs my cold plunge and stays on 24/7. It runs quietly which is nice as it’s outside in the garage. Make sure to put water into the pump before starting it up to get suction (if it’s outside of the tub)

I haven't measured it or anything, but to me it seems like works as expected! Got for outdoor tub and even when the prefilter (screened) seems to be getting little clogged it still pumps thru. Even when prefilter was pretty clogged it still worked, but could tell reduced flow so new was time to clean the prefilter. It was easy to install with common PVC fittings from store. Comes with a damping pad. Recommend if using it with anything attached to the house to use the pad. Mine is installed for a tub on the deck. Could hear it while in the kitchen, so using the pad really reduced the vibration noise. Part of it might have been since tub was new addition to outdoor deck, just wasn't used to it. Cause I don't really notice it anymore. But use the pad.

The last one lasted 7 years24/7 operation in my pond. It’s still working. The housing is finally corroding and the impeller has slowed a bit. Replacing before it fails.

This is my 3rd pump after having (2) active aqua pumps break (connection points). I use this for my cold plunge and its amazing, have had it for almost a year now with no issues. Very happy with it. I recommend using a thread sealant with it.

Pump lasted just over a year before the impeller disintegrated.It took me a few months to set up for the installation, so it never ran a full year

The pump works well so far, however it is very loud. I use it for my cold plunge in my basement, and if I'm on my main level of my house and there isn't a lot of noise I can hear the pump running.

good pump but output is not near 1200 gphResubmission. After taking pump apart ( impeller was broken cauding low output. Pump isok after fix
