Default How hot can you run a magdrive pump?

I'm thinking of making a basic solar water heater here in Arizona. I want to use a Via Aqua or other cheap pump, but I'm curious what very high temperatures do to them. To be on the safe side I'd like a pump that can handle 95C water.

Am I out of luck unless I spend a lot to get a pump made for high temps?

I dont think the aquarium pumps are rated for that kind of temp...(35-40°C tops?)
Problems I can foresee:
-melting plastic
-overheating/burnt out motor coil

Seem to recall the Laing D4 was designed as a cooling/heating circulation pump? - need to check its spec though. Not the same budget either

There are cast iron pumps designed to move hot water. Another option is using a plain old water pump from a car, with an electric motor attached to drive it. Thats under $50 and would shrug off the heat. I'll bet you could move a lot of water with one of those if you used a decent size motor.

this here is a good idea. theyre designed to take much, much hotter fluids, and would probabily have as good/better flow-rates than a pump for an aquarium
