Water Pump Replacement Recommendation?

From where did you buy the pad?

I just installed the 'sound-proofing pump pad': a cork center pad with rubber vibration pads glued to both top and bottom.  I screwed the pump through the top rubber pad into the central cork pad.  The screws did not extend any further. The pump pad was cut to a 6x6 inch square.  I then screwed four additional screws from the pad down into the flooring.  I also installed foam pipe insulation from both sides of the pump to the next pipe fitting (used about 9ft).
I estimate that the sound insulation cut the pump noise by about half (no sound meter).  The 'clattering' has been mostly controlled...but you can still hear the pump running both inside the Pod and when standing near the Pod (on the pump side).
But at least the pump probably won't wake up adjacent campers if I need to flush the toilet at night.
My total cost was about $40.00 which included shipping for the vibration pad.

Sorry I didn't include the company's URL: (Soundproofing Company): www.soundproofing.org
They have a lot of various types of sound proofing products.  Their prices are about average.

I received a private email from a forum member concerning pump noise.  He directed me to a company which sells 'pump vibration suppression pads'.  I first looked at 'SSF-sound suppression foam pads' but I couldn't figure out a way to attach the pump base on one side and the foam pad to the flooring.
They also sell sound suppression bases which consists of a thin SSF pad glued to the bottom of a cork block which also has an SSF pad glued to the top.  The base block has to be larger than the pump base. The pump is screwed onto the block top, resting on the SSF top pad.  Four new anchor points are drilled through the block outside of the pump base and the block is screwed to the floor.  Therefore, the pump base screws are secured to the upper portion of the block. Any vibration from the pump base is suppressed by the underlying SSF foam top layer. The cork center layer suppresses any remaining vibration from being transferred to the adjacent floor anchoring screws.  Finally the bottom SSF layer further suppresses noise from the block to the floor.
I also installed soft-flexible foam 'insulation' sleeves over the in & out pump hoses to keep them from vibrating as much as before.
I don't know the decibel decrease but to my ears there was a very noticeable noise decrease, enough that I don't think I am going to have to pad the interior of the pump enclosure with additional SSF padding!
(I would have included photos...but I am not familiar on how to include them in this forum)

Thanks for the suggestions...I am going to try to mount my present pump on a thick sheet of soft rubber.  The rubber sheet then would be mounted (glued) to a piece of plywood which would then be screwed to the Pod floor.  I think this would isolate the pump vibrations from the floor.
I also noticed for sale 'a pipe vibration deadening kit' which consists of two short flexible hoses with 1/2 inch threaded ends.  Supposedly the flexibility of the hoses keeps the pump vibrations from being transferred to the semi-rigid plastic piping.
