Noisy Mag 7

[JxMetal]

I purchased a used Mag pump and I plugged it in today to run it and it's a bit noisy for my likings. Is there anything I can do to get rid of the noise? I kind of sounds like it's grinding.

Thanks.

The mag 7's seem to be loud. I have two and they are both loud. You can try to put a bead of silicone on the bottom of the corners to cut down on vibration noise and check all the screws. Thats about it as far as I know.

Sometimes air can get caught inside the mags, which causes cavitation noises. Try turning and tapping the pump as it runs.

Mag 7s are just loud, try the Eheim 1260 and you will wonder if it is even on. I use my old mag 7 for a mixing pump now and when I hear it running I wonder how I put up with it for so long.

There are a ton of "noisy Mag7" threads. They are really noisy pumps. I tried everything to fix mine to no avail. I replaced it with an Eheim 1260. Not only night and day difference in noise, but I picked up a ton of flow too.

A cheap way to reduce the noise is to swap in a Mag5 impeller which converts the pump to a Mag5.

check to make sure that nothing is broken off the impeller or the face plate. My Mag 7 started making noise due to a chiped face place part....which threw the balance of the impeller off so it started rubbing.
