I just replaced the bearings & shaft seal in my Hayward Northstar pump. Put it back together and the pump was making a noise like this:

(this isn't my video, but the pump was making the exact same noise)
Removed the impeller ring and the noise went away. Seems to pump fine without it; does anyone know what the purpose of the ring is? Is it supposed to help with self-priming?
