Noisy Vortech MP10ES W

[VJV]

Hi,

This is my first post in this forum so high everyone. All help is greatly appreciated

I have purchased an MP10 and even after carefully trying to align it in my tank (a 12g Biorb Life acrylic tank with 6mm thick walls) it is still making a very loud rumbling/rattling noise.

I have turned on the dry side on its own and it makes a slight whirring sound but it is very low. However, the wetside when connected creates a very loud rattling. I have tried to align it as per instructions and it does get to a int that it is not as loud, but still VERY loud!

I have read through countless forums several people saying that they actually sleep right next to theirs and that as long as it is below 80% power it is barely audible so I am guessing there must be something wrong with my pump.

Please help as I was planning to get another Mp10 and a MP40 for my new 75g but I can not leave with is noise level.

Kind regards

Vasco.

Vasco,

I would recommend using the dryside spacer if you aren't already. Also, try running the new MP10 in constant mode at a very low speed. Gradually increase that speed over the course of 2 weeks. If the unit is still loud at that point, please contact us directly to have it replaced under warranty.

Wow, that was fast!

Thanks. I have added the spacer and left it overnight at 20% but the sound did not change a bit. I am pretty sure the noisy is coming from the wet side. Given that it has no engine inside why would a couple of weeks change anything? Also, when holding the wetside in my hand and shaking it slightly I can feel the magnet assembly inside moving up and down. Is this supposed to happen?

Thanks again Alex.

Kind regards

Vasco

Just went through a bunch of YouTube videos and there is definitely something wrong with my wet side. On those videos the only sound you hear is the whirring of the motor. No loud ratling/rumbling noises like mine...

I guess I will need to return it

VjV,

I would recommend calling in today if this continues to be an issue.

Hi Alex, unfortunately it does. I'll take it back to the LFS... Hopefully I'll get as good support in Lisbon as you seem to provide in the US... I fear it will probably take a long time to get a new wet side...

VJV,

Please keep us updated!

Dear Alex,

I'm happy to report that after a lot of tweaking and another week it seems to have quieted down significantly. It is still far from silent, but I am guessing that this is the trade off for having less heat inside the tank. I can still hear some ratling but is much lower.

I will post a video later this week positioning an spl meter next to the pump so that you can hear and see the decibels I am getting, and hopefully let me know if it I'd normal or if I should indeed ask for a new wet side at the LFS.

Thank you very much

Vasco

Hi VJV, not to scare u off. I bought a mp40Wes in late Aug 12. Upon running in my tank, I heard a rattling sound and it was gone. Feeling the uncertainty, I sent it back to my lfs And found no issue.
Just last wkend, this pump stop moving and based on the lights on the controller, it means somewhere it's jammed.
I took off my wet side n tried to turn the propeller n it required some effort to turn it.
Opening the back cover of the wet side, I found a "quadrant" of the magnet had bloated up with brownish matter. After googling, I found out there's a couple of pple who experience this.
One way for u to check is to open up the back cover of the wet side and see if there's any circular scratches on this inner part of back cover.
As my case, the protruding magnet rubbed against the backcover and created a deep circular groove.
I suppose the back cover cannot touch the magnet at all as explained by my lfs. If sand gets into between backcover n spinning magnet, it will cause more friction n spoils the pump.
