FWIF when I replaced mine a couple of weekends ago, my faile pump looked similar to yours, maybe just a little bit less impeller damage. Mine started to leak and then I got some slight chirping noise before i shut it down after about a 2 mile drive home.

I didn't even take a close look at the impeller until after I got the new one back in. No bits in the old coolant and I didn't back flush.

If I had to do it again, I would back flush, espacially the the engine a couple of times. But I don't know what the procedure is.
