Low Frequency vibration MP60

[drtechno]

Hi

I am curious if anyone else has run into this issue - my MP60 is producing a low frequency vibration that is barely perceptible, but when its quiet, it can be heard and felt on the second floor of the house. It's not the typical rattling that you get with an improperly aligned wet/dry side, its a low frequency hum almost. When we are trying to go to sleep (again, the floor above and other side of the house) you can hear the pump powering up and down as it goes through its program. It's driving me crazy. The MP40s are dead silent.

Is there an issue with this pump? Is this expected? Yes, the correct size spacer is installed. Yes I have tried realigning the pump. And yes I have cleaned the pump

Im sure you tried taking the spacer out?
I think it is the nature of the beast when operating above 50%, some noise.

Haven't tried it without the spacer. Doesn't it say that without the correct spacer you could damage the pump ?

When I touch the dry side, it is definitely vibrating. Its crazy that I can feel/hear this 20 feet away on a second story of the house. Probably the vibrations are getting transmitted.

So this is expected behavior at 75% power?

Both of mine are practically silent. I have to be within a foot if it to hear it running

How old is the MP60? When was the last time it was cleaned? An imbalance of the wet side by a snail or dirty propeller can transfer a vibration to the dry side making it seem the dry side is the issue when actually it is the wet side causing the issue.

Good advice

~4-5 months old

Cleaned 2 days ago. Its clean yet still when you put your hand on the dry side there is mild vibration which I assume is what is transmitting

Remove the wet side and see if you still have the vibration. Good troubleshooting technique.

Great idea !
? so just hold the dry side in my hand and power it up to see if there is vibration I assume?

If there is, does that mean I need to contact Ecotech as there is nothing more that I would do ?

Yes and Yes!

Actually since it is an MP60 you can leave it hanging on the tank glass as long as you are using the small support hook and the cable is tie wrapped to the tie wrap mounts.
