You don't need a pump to pump water into the sump, in fact, pumping water from the tank to the sump, is a bad idea.
Best to use gravity to bring water from the tank to the sump, and use 1 pump to send water back to the tank.
Just a thought as to why 2 pumps is a bad idea
if you use 2 pumps, what if one fails, and not the other?
When you use 1, if it fails (and they all do, at 1 time or another, due to power outage, snail in the impeller, electrical short etc)
Water stops, sumps fills a little, but when the overflow is starved for water, its on hold until you fix it, and the end result is
a dry floor, and water stays in tank, fish alive until you fix the problem.
Lets say in your 2 pump scenario,
the pump in the sump stops, for any of the above scenario reasons
but the 1 in the tank doesn't.
End result
Dry tank, dead fish, wet floor, etc.
