Pond Boss Forums AERATION Systems questions Stopping vibration (at least reducing it)

Just recently I install a temporary pier on the pond, actually it is the deck (6x12) that was in front of the trailer I used to stay in (moved into the house even though it is not done yet). With the low water this year I added a Vertex Air 1 Plus XL2 system to the pond and the housing for it is on the pier. So that it wouldn't vibrate off the pier I boxed in the corners of the aerator and put 2x4s across the top to hold it done. This causes the vibration of the pump to be be transfer to the pier. Can anyone think of a solution that would stop/reduce the vibration on the pier? I been thinking of getting some rubber mat and put it between the housing and pier.

Try these.

Those two links are good ones, What I suggest trying first is that since the mounting pad is approx 24X24 inches that you take a piece of carpet that is 23 1/2 X 23 1/2 ( if you dont want to see the edges) and set the pad on that and then take deck screws or small lags and gently pull the compressor mounting pad down on all 4 corners so that it does not touch the pier.The underside of the poly pad is criss crossed with a lot of support so the outside edges of the pad do not have to touch the carpet.We use this method a lot where hurricane codes require the units to be lagged to concrete and that causes the vibration and decible level to go up.I use outdoor carpet on all of our installs that are not mounted on the ground. You may have to use two pieces of carpet depending on how thick a carpet you use.

Would a 1" or thicker pad of closed cell foam (so it wouldn't absorb water) work? Like part of an exercise or yoga mat.

Placed under the mounting pad.

As long as you still pin the corners any kind of padding should help. We use the outdoor carpet that looks like a grass mat and put the top side down so that water can get thru. I prefer to have the corners pinned when the units are close to the water since often owners seem to not lock the lids closed and have had a few "sail" into the water because of the lid flying open in high wind situations. ( Sue hates to warranty those) Lagging them down to 1/8 th or .125 (just had to toss in the decimal )from the deck surface makes for a clean looking install.

Thanks for the suggestions. I will have to look around I think I have some old outdoor carpet laying around. Sounds like the way I pin in down right now is half causing the problem. So I should lagged the unit down from the inside, didn't think about that.

Ted and lassig:

I've also seen rubber isolators, which have a bolt )or threaded rod) coming out the bottom, a rubber "puck" for lack of a better term, then a bolt or threaded rod coming out the top. The rods aren't connected, they are secured to each other via the rubber "puck".

Page 1368 if the link doesn't work. For some reason the link takes you to page 1360. The ones that I was thinking about are on pg. 1368.

Thanks esshup,The compressor does have rubber motor mounts that have independent threaded rods on each end, This single piston series as all single pistons are not as well as balanced as dual pistons and can have additional vibration than the larger units.I have not tried mounts on the pad but guess that might work too but may give the entire unit some movement. Lassig. I would just lag at the 4 corners of the poly pad with a small lag and perhaps a stainless flat washer.

Ted,

Thanks, I am assuming that I just drill a hole through the poly pad for the lag bolts.

Yes, Be sure to look on the underside first so you are not drilling thru a horizontal support.
