You have a couple of choices in the pump dep't. Shureflo make a 'Whisper King' that is a low RPM 2.0 GPM pump that is marketed as the quitest in the industry. If you want more volume, they make 2 microprocessor controlled variable speed quiet models, a 4.0 GPM and the creme-de-la-creme...... the Extreme Series 5.7 GPM model.
Prices range from $105 for the Whisper to $168 to $225 for the super-duper version. The pump silencing kit and possibly a rubber mount/vibration isolator is also a great idea.
Let me know if you need help in getting one of these.
