mp40wes

jones02 · 08/20/2012, 09:09 AM

So I just sold my mp10s and got a mp40. Why is this thing louder then the 10's? Its inn a bedroom and the gf hates it! Its only been up and running a rew hours but ill have to give it a couple days.

scarface70706 · 08/20/2012, 01:50 PM

because the pump is bigger.

Align the wet-side properly and give it a few days to simmer down the noise but don't expect it to be quieter than MP10s.

jones02 · 08/20/2012, 06:10 PM

I'm thinking on just trading it for 2 mp10's

Mmiller40gt · 08/20/2012, 07:21 PM

I think the mp10 and mp60s are balanced. The mp40s are not. There was a thread this not long ago

jones02 · 08/20/2012, 08:19 PM

jones02 I am still waiting for my Hanna Checkers, Pm'ed you and have not got a response. It has been close to a month now since I sent the money.

^^^^ thats what I did, but not because the mp40s or 10s were noisy, I just have a toddler that touches everything and I was worried about him ripping the motors off the side of the tank. however, I couldnt really hear my mp40, or mp10 unless I stuck my ear up to them

My mp40 has been dead quiet 20 minutes after I first installed it... Line up the spacer correctly then fine tune the placement my slightly twisting it between the wet and dry side. It made it totally silent. It was a bit noisy until I set the glass spacer correctly, too.

I guess I'm not the only one waiting for shipment. I've been waiting for my dosers for almost 6 weeks now. He said he shipped it but nothing yet.

Well this doesn't sound very good.

The MP40 is bigger, more powerful, so it will be louder.

worm5406 · 09/14/2012, 09:30 AM

As long as your spacer is set correct and it aligns there should be minimal noise.

Off set it slightly and then it is noisy. I had my spacer too close and it was like pulling (drag) too much and noisy.

I have 2 MP-40 EWS on my new set-up. I was really peed off about how noisy they were, despite being super careful with glass thickness setting and trying all sorts of delicate alignment adjustments over a week. Just could not get them any where near quiet.

Fot the price we pay, it is a very noisy pump !!!

So....following the thread on RC http://www.reefcentral.com/forums/sh...earings&page=4

I bought new bearings (grade 5) from Boca and replaced the original ones. Whilst I had the unit apart, I put the dry side magnet on a balancing rig I use for model helicopter rotating parts and it was horribly out of balance.

I did not want to start filing and drilling this magnet to get it into balance so I tried many small variations in position with the magnet and the rotors untill I got the best fit/balance condition.

Now the unit is whisper quiet ....cant hear the ramp-up from 1 foot away....and I will do N0. 2 next.

Please note in the instructions on the Thread that all of this work voids any Manufacturers warranty and is done entirely at your own risk

But it does work !!!!!
