Looking for a way to silence my danner mag drive 350 for my return pump I looked around for premade dannet suction cups or something. Also read of people putting a mouse pad under them. I used 4 small rubber air compressor feet (you could use a large suction cup) and (4) 1/4" nylon screws and bolts, and drilled the 4 holes in the pump mount to 1/4" and assembled as you can see here. It helped silence it a good bit.
