    I'm setting up a new tank and while leak testing the tank and plumbing, I discovered that the return pump is a lot louder than I expected. It is an eheim 1262 and has a hum that is noticeable across the room even when the stand doors are closed. I've tried sound proofing without any luck so I'm looking at either selling the tank and drilling a new tank for a canister filter and external heater or trying a new return pump.

    So my question is does anyone have any suggestions for quiet pumps in the $100-$200 range. I know, I may be asking for to much.

    It depends on your application... many people love the VarioS pumps if the height of the plumbing is not much.

    I'd think that a cheap used pump will go further then a canister filter.

    Consider posting in the classifieds for a pump wanted and the specs you need. Good chance someone has one laying around.

    There must be something wrong with your Eheim 1262. I had 2 of them and ran on 2 difference systems. One of the most quiet return pump I ever owned.

    That is what I read which is why I bought it in the first place.

    Did you buy it new/used? Try to take it apart to see any missing pieces or broken parts.

    It was used. Yeah, I was thinking it was time to open it up and take a look.

    If nothing else, put it in a bucket with some vinegar for a stent.

    Also check the bushings and the drive shaft for any wiggling that seems loose.

    If everything looks good it could simply be your plumbing design... that seems to have been my problem.

    I stripped it down last night and it is probably the cleanest pump I have ever seen, not a bit of build up and seems to run smooth. I've run it in an vinegar bath overnight with no change. I'm beginning to wonder if the problem is me. I may just be sensitive to that frequency.

    So you are using some flexable/silicone tubing somewhere to help dampen the vibrations and not 100% pvc right ?

    Yes, I have about 18" of vinyl tubing between the pump and where the PVC pipe is attached to the stand. Last night I had it sitting in a tub, connected to nothing, sitting on some filter pads and I could still hear the hum.

    Well then that is your answer, either a worn part you don't see or you're the sensitive kind (o;

    I'm sure you have but also made sure you ask someone else if they hear it and it bothers them.

    Maybe I'll order a replacement impeller and see if that makes a difference.

    +1 on the varios pumps. I have the varios 2 in our 65 gal. I never hear it. And we purchased the skimz quiet pump for the 93cube and that’s also super quiet and powerful. Moves a lot of water and spent less than the varios.

    Echo what DG said. Try silicone tube instead of Vinyl. You could also try sound damper pads from BRS.

    Perhapse use a DC pump. Jebao DCT is your alternative without breaking the bank. I also have an OTP 3000 turbine you can test it for a few days.

    At this point I'm not sure if using silicone tubing will make a difference as I can hear the hum when it is just in a bucket running. In the bucket, it has been sitting on a foam pad with the outlet not attached to anything so there is nothing to vibrate against.
