Sump Pump?

[tinpusher]

I have a Mag return pump in my sump. I live in a house that gets hot in the summer and I am concerned about the heat generated by the pump. I have an idea I want to run by you guys.

Can I put the pump in the sump on a platform above the normal operating water level of the sump but below the power outage water level. It would normally run in the air and not heat the water. If it ran dry for whatever reason it would stop pumping until the tank drained into the sump up to a point where the pump was underwater. The pump would then be primed again and start pumping. Does this make sense?
