Nope, no way to really avoid using the pad to absorb the mechanical vibrations the pump makes. You need to give it less compression to allow it to absorb more vibration.

I have that pump and mine vibrated too much to use the mounting bracket. That vibration was passed into the frame and the noise was beyond my comfort level. After seeing what loose foam did for martin's testing on various pumps I removed the frame and let the pump sit on a large piece of foam folded over and it worked perfectly. It's "loose" but the pressure from the tubes keeps the unit in place.

I've since tried the 450S pumps from Koolance in their 452X2 product and with both running at 12V it was almost silent compared to the noise generated by one EK pump on the bracket. I suspect either the pump has a design issue (smaller pumps that run fast need to be in larger containment devices like large blocks of acetal to keep vibration down) or that's just what you get w/this pump and the hard foam they provide. Maybe you can double-up on a softer foam and use the bracket w/o attaching it to your frame...but until you mute the vibrations of the pump all it's going to do is pass those vibrations on.
