si_sphinx Posted January 22, 2011 Report Share Posted January 22, 2011 Yesterday I removed my return pump from my sump and plumbed in externally to reduce vibrations. Now i have it set up this way, it is even noisier. The vibrations have stopped but the motor itself seems to be louder than the vibrations were. :an!gry So I have incased the pump in a cardboard box lined with poly and filter wool for sound insulation, but it doesn't seem to make much of a difference. I think having the pump in the sump, the water insulated the noise from it. What has anyone else done to reduce the noise from the return pumps? :dunno: Any ideas would be appreciated. Thanks.

livingart Posted January 22, 2011 Report Share Posted January 22, 2011 soft hose instead of hard pipe connecting to pump? Quote Link to comment Share on other sites More sharing options...
henward Posted January 22, 2011 Report Share Posted January 22, 2011 what brand of pump do you have? cheaper pumps may be reliable, but noisy in nature. if you wnt quiet you are just gonna have to splash out for eheims Quote Link to comment Share on other sites More sharing options...

Put it back in the water, why would you think plumbing it externally where it doesn't have 100 lbs of water damping the noise would be quieter?

si_sphinx Posted January 23, 2011 Author Report Share Posted January 23, 2011 It has soft hose going to and from the pump. I thought the vibrations would stop plumbing it externaly as that is what other people have done. And it did stop the vibration through the sump and stand but the pump itself is noisy. The pump I am using is an ALEAS AH-5 submersible pump rated at 6000LPH at 0m head height. (A cheap one from trademe as thats all i could afford at the time). Maybe i should get a better pump?

diver21 Posted January 23, 2011 Report Share Posted January 23, 2011 put the pump back into the sump and put some foam under the sump? Quote Link to comment Share on other sites More sharing options...
spoon Posted January 23, 2011 Report Share Posted January 23, 2011 can the pump be screwed to something solid? to dampen the noise from the pump? not the cabinet its in though as this may amplify the noise even more Quote Link to comment Share on other sites More sharing options...
Scottie841 Posted January 23, 2011 Report Share Posted January 23, 2011 Hang the pump in the sump so that it is not touching anything and the water should stop mots if not all the noise Quote Link to comment Share on other sites More sharing options...
si_sphinx Posted January 23, 2011 Author Report Share Posted January 23, 2011 The sump is sitting on poly. I could screw to pump to a board but that would only reduce the vibration but its not really the vibration that is bugging me. What return pumps have everyone used that are quiet. I need it to be reasonably quiet as the tank is in the lounge right behind the couch and I have to turn the tv up to hear it :roll: Hang the pump in the sump so that it is not touching anything and the water should stop mots if not all the noise That sounds like a good idea, I might have to try it. Hang it from a chain with a piece of rubber between the chain and pump? Quote Link to comment Share on other sites More sharing options...
David R Posted January 23, 2011 Report Share Posted January 23, 2011 Both my Laguna 7500's are really quiet, but rather pricey. I agree with Henward, you get what you pay for with pumps... Quote Link to comment Share on other sites More sharing options...
Adrienne Posted January 23, 2011 Report Share Posted January 23, 2011 when I ran a sump I used a very large eheim, it was in the lounge and you could not hear it Quote Link to comment Share on other sites More sharing options...

henward Posted January 27, 2011 Report Share Posted January 27, 2011 eheims can go up to a very high flow. but high price:D i reckon just condtion yourself to forget about the sound:D once i did that with the beeping of my fire alarm.... i could not hear it anymore, but everyone else could, even if i stood under it, i actually could not hear it. weird:D Quote Link to comment Share on other sites More sharing options...
Joshlikesfish Posted January 27, 2011 Report Share Posted January 27, 2011 Could just use an external filter? Quote Link to comment Share on other sites More sharing options...
Ira Posted January 27, 2011 Report Share Posted January 27, 2011 Could just use an external filter? Most have pretty poor flow at the 3-4 of static head they'll be seeing in a sump. They don't see any head when installed normally. Quote Link to comment Share on other sites More sharing options...
