After owning well over 100 vehicles, I've only had problems with the clutched fans, never the direct drive ones.

I think your incident was one of those happenings that are so rare as to be almost unheard of. I suspect our water pump was already defective, probably either worn out or corroded until the metal was too thin to support the pull of the fan.

Does anyone else know of un-clutched fans exploding the water pump?

I would roughly estimate that at 3,000 ROM the fan would put around 10-20 lbs. of pull on the hub, certainly not enough to do any damage.

Let's hope no one else has this problme, I can see how it could cause a lot of trouble, even an accident.

The nearest experience I had was in a Ford pickup with a replaced radiator. The radiator mounts weren't tight and the suction of the fan pulled the radiator back and the fan chewed right through it!
