A few thoughts...

1. Make sure none of the securing hardware is touching the case. It might be worth considering replacing the nuts & bolts with a tiewrap or other soft fastener.

2. How sure are you that its the pump and not some other part of the system (PSU fan, HDD, etc)

3. Try adding some vibration damping material (aka 'Mass loading") to the case under the sound absorbing pads. Asphalt roofers tape is good, or you can get mastic sheets from McMaster Carr. This stuff needs to go right up against the case metal, and can really do a good job of reducing resonant noise.

Good luck.
