Yes, things like this are done all the time. You may alsowant to look under
"ejector"

>> 1.) Is this true?
All pumps will have a temperature rating. If there is a sump of some sort,
the temperature will be moderated by the water already in the sump.

>> 2.) What temperature should the pump be rated for? The model he is

That should do it. We use 140 degree pumps at work for cooling water that i
130 to 150 and they last for years.
>> 3.) Is this something that a licenced plumber needs to do?
The town probably requires a permit for plumbing. Many people don't bother.
It can be done by someone with a little experience. The system should have
a check valve on the outlet to prevent backflow. There should be an alarm on
the sump if the water reaches a certain level and the pump fails. Lok at
