I did hear it at low RPMs like you said, but I have a loud exhaust and the sound of the exhaust masked the sound of the water pump pulley so it was hard to tell. When I removed my serpentine belt to twist the pulley it didn't twist so I was still not sure if it was it, but when I removed it, it was obvious. Give it a shot and see how it feels. If it's not it and you have never replaced your pump, replace it anyways. When mine went out it made even weirder noises, constantly leaked coolant onto my headers and made a very dramatic scene.
