Pump mounting suggestions?

I've been watercooling for 7+ years now, and my Eheim pump is giving up the ghost (finally!)

I've ripped out all of my watercooling equipment from my old setup and put a heatpipe in there to keep it up as I am rebuilding.

One thing that I noticed right off the bat is how much quieter my current setup is with the pump out of there. I am surprised at the amount of noise/vibration I was getting off that thing. Some of that I can chalk up to the age of the pump as it was getting quiet loud.

I have a spare new Eheim pump I am going to use in a new case with new equipment.

My question is does anyone have a solution for mounting the pump? I am looking for a clean solution to mounting it with in my case, preferably with some sound damping added to keep the vibration to a minimum.

My old pump was was directly mounted via zip ties to the case, one of the reasons I am sure it was loud in it's later years.
 
guess it depends on your layout, case type, etc etc post a pic...
 
Drill out the slot in the foot mounting to be a hole shape and find a soft rubber gromett to fit (or find a grommett and drill the proper hole size. Use a large flat washer on the non case side followed by a split lockwasher and then double nuts. Tighten just until you barely start to compress the gromett and use the double nuts to lock the hardware in place. You could also add a piece of sheet rubber gasket material found in good hardware stores under the pump as well.

As you are probably aware the trick is to isolate the case and hardware completely from the pump itself. None of the mounting hardware should touch the pump without some vibration absorbing medium between them.
 
Bill's suggestions are good, but if you want a simple solution, Petra sells a gel pad that sits under pumps. Its mainly made for DDC/D5 pumps, but I don't see why you couldn't use it on your Eheim pump. It can be found here.
 
I don't think it will transfer vibration because of what he described is what i've seen for harddrive mounting on some cases, except that it didn't use wahers. I might be getting the wrong picture but from what he said, the pump would be isolated with the rubber grommet hence, the bolt only touches the base of the pump by the grommets.
 
My ddc3.2 has two pieces of rubber glued to the bottom,then its glued into the case,nill vibration noise.
 
Thank you to all for the responses, it is much appreciated.

The rubber grommet idea makes sense. I could probably make small enough holes to mount up the pump in between the sides of the hard drive cage, the hardware store had some pretty small grommets if I recall correctly.

I've already had a bone headed moment with this new watercooling setup. I was so intent on mounting the radiator on the out side of the case. I put two holes in the back with rubber grommets down by the pcie/pci slots thinking of running the tubing out the back to the radiator. Then when I mounted the radiator I got to looking at it and "duh" I could have just put two holes up by the 120 mm fan hole and put the inlet and outlet barbs of the radiator directly into the case...

So now I have two extra holes in the back, though they do look like they belong, I don't know what I was thinking originally. :rolleyes:

Waiting on some extra 90 degree elbows to help me route my tubing more efficiently Had to get thread converters for the good old metric eheim.

Petra's gel-stuff is awesome, it's cheap, and surprisingly grippy.

I've seen it before but I've never used it. Do you simply bolt the pump to something through the gel or is the gel itself some type of strong adhesive?

Thanks.
 
Industrial Velcro. I decided to use it for my current build to avoid having to drill. It turned out being a fine way to isolate vibration as well.

You can drill holes through it, but I find that simply placing your pump on top of this and have it "float" that it doesn't move. The Gel material tends to be dense enough that neither the pump nor the pad move.
