Unhappy WATER PUMP DIED REALLY BAD

I have an Early build 99 7.3 F350 cc,lb with about 135,000 on it I'm the second owner.
About a month ago I did a complete flush of my coolant system. I followed the guide lines that someone on here wrote up. I flushed the system 3 times with distilled water until there wasn't any green anti freeze coming out of the flushing. Then I flushed it again with distilled water to make sure. I then added 4 gallons of green anti freeze and topped it off with distilled water and also added 5 pints of Napa coolant system conditioner.
Since the coolant flush I have driven about 4-500 miles on it. A lot of 70&80 MPH highway miles. The other day I started the truck and heard a growling noise from the engine. I checked the engine and everything looked fine. Could not locate the noise. Yesterday the noise came back but then stopped.I had to run to town (8 miles) and when I stopped I noticed that I had a heavy leak of anti freeze pouring out from under the truck. I was headed over to my buddies repair shop when I heard a loud noise, I could tell that I lost the serpentine belt;no power steering and the battery light came on. The fan and Fan clutch came completely off the water pump.
I'm wonder if any expert out there can tell me what happened. I'm wonder if cleaning out the coolant system got some scaling into the water pump bearings after the flushing.
Now I need a new water pump, a fan and possibly a new fan clutch and a radiator ,plus more anti freeze.Also the Napa conditioner is re and tints the whole system a pinkish red color fluid. does anyone make a green color conditioner for the diesel trucks that still use green anti freeze.
Sorry for the long post

Also in July I lost the HPOP on a trip. It made the tow truck driver happy. Had to tow it almost 100 miles.
My wife think this is all caused by me putting in a F5 tuner from DP Tuners

No one out there has any ideas of why the water pump went out. I did that flushing to avoid what happened to the water pump. I don't think the original owner took very good maintenance of the truck. I bought it several years ago with only 77,000 miles on it.[B]

Are you saying that the fan and clutch fan broke off the shaft of the water pump?

Unhappy

Yep, that's what I'm saying. Took out the radiator too. plus broke off a fan blade. There was hardly any warning.Like I said heard some growling sounds from the engine. Nothing leaking or loose. Then bang everything went at once. The bearings looked rifle bullets after they hit something.
There goes my Elk hunting trip for the weekend.

yours fell off? I can't get mine off (water pump pulley). If you know how to get the pulley off I would appreciate the information. I have the fan and clutch off, but there is a shaft on the the water pump that the pully will not slide over (to big), it has the flat sides on it to hold the shaft while tuning off the large nut on the clutch, it will not budge with the pulley bolts removed. I think it may be rusted on but I have used penetrant liberally, tapped first and then hit the shaft with hammers trying to break it free. I do not have a manual so I am shooting in the dark. The vehicle is a 1996 E 450 elf (shuttle bus) with a 7.3 diesel engine. can you help.
