Hi, can anyone tell me what this impeller is made of? I had it in a pump, and sent it out before I could give it a good look over. I was told its alumnum, but I have only seen the Berkeley impellers, that are painted with that green coating.:)hand

Looks like it might be an early 90's Dominator Aluminum. Also looks like the stuffer ring was machined off the back side furthering my suspicion. They were a gold anodized in color and most would also have a year stamp next to the cut stamp near the inner hub.
