About 10 years ago I put the pump on rubber mounts and wrapped it and the plumbing from it in dense foam. That cut the noise maybe just 20% or so.

As mentioned, the problem is usually not the pump itself, but the outlet hose vibrating and banging the pipe it's connected to on something.
Took me years to figure out a solution that actually works so well at dampening pump noise that I had to add a light so I'd know when the pump is running. 2 pics and a video as proof of performance
start here. Anything else I had tried previously on a variety of trailers weren't anywhere near as successful as this. :B To the OP - you likely don't need a new pump but rather a proper pump installation. ;)
