Yep it'll work fine. As far as noise goes, my experience with LG pumps is that they're actually very quiet, but I've only had 2 of the free flow variety (3-MDQX's as sump returns...they actually replaced the above-mentioned noisy Iwaki when I moved the tank to my new house which had no separate sump room) so I can't say for sure about the pressure-rated ones. Best of luck!!
