If you have a sump pump and it starts up, it will burn out very
quickly, they are water cooled. Hot water is not going to cool it.

Not really. I run sump pumps on a regular basis up to a constant 16 hours a
day in 125 degree water and they last for years. I have another self
priming pump that will get rid of 190 degree water in a flash and has been
doing so for about 15 years, but that is only about 20 to 30 gallons at a
time.

Zoeller spec is 130 degrees and most residential water heaters are right in
that range.

The water will cool quite a bit before it gets to the pump too.
A little different than electric motor cooling, but this reminds me of
a time we had a small smouldering detached lagging fire
in a boiler room.
Only needed a little water to put it out.
I grabbed a bucket and filled it from the de-aerating feed tank test
tap. That's hot water - a lot of it flashes to steam as you tap it.
But there were no other fresh water taps nearby.
As I start to walk to the lagging to douse the fire, the top watch
yells, "Smith! Is that hot water?! Don't use that!"
I couldn't effin believe it.
He insisted I waste CO2 bottle charge on it.
I didn't argue much. Not worth it with this guy.
