Help, pump mounting ideas

I need to know how important vibration dampening is when mounting a pump. I am concerned with it since I know all of them have vibration and it will be easily transmitted through my ultra light aluminum case. The pump came with rubber suction cups and I am considering drilling a hole through each about halfway between the edge and center and screwing them to the case. What is a real easy way to mount my pump so I don't need to worry about this?


here is where it will be mounted.

    make sure it's solid, otherwise your case may buzz which gets really annoying really quickly.

    Rubber or Neopreen(sp?) washers on boths sides of the bolts? Might help out. Also might cause more vibration.

    Larry,

    I purchased a pump mounting kit which is basically 4 bolts with rubber standoffs. You bolt this to the base of the Hydor and bolt it to the case. It works really well, no noise or vibration.

    I'd suggest you make or buy something similar, failing that bolt the base to the case with some thick foam sandwiched in between.

    Thanks for the suggestions. I went to Home Depot and bought some small machine screws, nuts, flat washers, large diameter/ small hole neoprene washers and some rubber shoulder washers that will allow no case metal to come in contact with the machine screws. I have taken the neoprene washers which are very large and bent them in a butterfly pattern to make a air space which I molded with a heat gun. They will in turn go over the rubber shoulder washers that the shoulder fits in the holes in the case with a smaller neoprene washer under the rubber suction cup base of the pump and drilled a hole which is all bolted together. I put the case on the sink and put a piece of hose into the sink to pump out water and another hose to return water. After about 5 minutes the pump got real quiet and I couldn't hear anything, even placeing various objects on different parts of the case to detect vibration. :thumbsup:

    I have a late suggestion, just in case anyone else needs it. You can get vibration dampners that are basically a rubber biscuit with threaded washers on either side that you bolt to whatever you want to isolate from the surface it's going to be mounted to.
    You'd bolt 4 of these things to your pump and then bolt the pump to the case and the pump would be floating on the dampners.
    I've seen them as small as a dime in diameter with a thickness of just over a quarter inch and 10-24 holes in the mounts.
    They sell them for mounting electric fuel pumps at hot-rod shops and you should find them at places like Home Depot or Orchard Supply Hardware.
