Couldn't you use something like this to set a timed delay before the power resets to the pump? Use the relay as NC, have the float switch trip it, delay timer keeps it open to keep the pump from cycling quickly.

Just getting into this stuff so I'm probably wrong and using this thing will start a fire
This may not be the right part, but the concept should work, right?
