treesprite April 5, 2009 April 5, 2009 My return, a GenX model GX6000 (1587gph) is extremely noisy (I have it internal but it can also be external). Is there anyone who is familiar with this particualr pump who has a good technique for silencing it? I tried putting a pad under it in the past but it didn't help at all. Mostly I guess it is a vibration humming noise. I am also wondering if anyone has used pipe insulation over tehir pipes to cut down on vibrationa dn flow noise. Info appreciated, thanks.
L8 2 RISE April 5, 2009 April 5, 2009 don't have experience with that pump in particular, but try a pad, and flexible hose on both the intake and output.
treesprite April 5, 2009 Author April 5, 2009 I already tried using a pad under it which did no good (many months ago). What difference would a hose make on pump vibration noise as opposed to hard pvc?
L8 2 RISE April 5, 2009 April 5, 2009 When its hard plumbing, the vibrations extend up the piping and to the glass tank. Hence, a louder pump.
reefmontalvo April 5, 2009 April 5, 2009 When its hard plumbing, the vibrations extend up the piping and to the glass tank. Hence, a louder pump. Mostly I think you meant to say the flex hose absorbs a lot of the output vibration which in turn quiets the pump "a little". It also helps place a thick pad along with the flex hose.

If you're trying to quiet the pump itself, I've never heard of finding a way to quiet the actual pump, just limit vibration, and therefore noise....
Boret April 5, 2009 April 5, 2009 Have you inspected the ceramic shaft and the propeller to make sure they are in good shape? Maybe, if it is a bit unbalanced it might be producing excessive vibrations. Just a thought.
Jon Lazar April 5, 2009 April 5, 2009 treesprite, Did the pump get louder recently, or has the pump always been loud and you're just now getting tired of hearing it? The reason I ask is that some pumps are simply louder than others, and there's only so much you can do. When I first started I had the Genx-40 pump, and found it much too loud for my liking. I switched to a Poseidon Titanium T4 and that pump is completely silent. There are probably other pumps that run silent too, but the Genx-40 isn't one of them. I'm not familiar with your particular pump. Jon
treesprite April 5, 2009 Author April 5, 2009 It has always been noisy like this. I think if nothing was touching it things would be a lot quieter - it's like the whole sump and everything in it vibrates. Some re-arranging so stuff isn't crammed together on one end of the sump might help, but then I would have to use an extension cord which I am trying to avoid.
GaryL April 6, 2009 April 6, 2009 maybe you can show it provocative pics of it all around town..... that will keep it quiet! i got nothing.... maybe box it in with filter floss? you may have to change it from time to time?
Kengar April 7, 2009 April 7, 2009 Sure fire way to quiet it down: unplug it! Seriously, though, you say you have it internal. If possible, in addition to using flexible tubing instead of PVC, perhaps you could suspend it in some fashion by cable ties, dental floss, or some other non-corroding means so that it does not sit either directly or indirectly (i.e., via pad) on the bottom of the sump. In other words, suspend it within the water column.
dbartco April 7, 2009 April 7, 2009 Are you restricting flow in any way (ie, a valve)? Reducing any backpressure might help a little.

In other words, suspend it within the water column. I had actually considered suspension in the past but there isn't really a way to do it. Even just a fraction of an inch off the bottom would help, I'm sure. Are you restricting flow in any way (ie, a valve)? Reducing any backpressure might help a little. I do have a valve restricting the flow some because the pump is too powerful (been thinking about adding a second overflow box so I won't have to do it), but the pump has always been noisy. I think it was less noisy when I was using a sump tank that was sitting on the floor on carpet.
treesprite April 8, 2009 Author April 8, 2009 I put a second overflow box on my tank, now I have my pump going full without restriction. I can't tell that there is any difference in noise since opening the valve all the way.
Kengar April 10, 2009 April 10, 2009 Although internal, submersible pumps such as this one may be cheaper than external, is it really worth the cost savings to have all of this aggavation? I have Poseidon T4 external; can't hear it at all!!!
