Um.... and you want to put this in your wet/dry sump?

That is way too much pump for that size tank. That pump is too much pump for most tanks, and adds a ton of heat. Those that use them also use a chiller just to deal with that. So now you have two items sucking up tons of electricity around the clock, plus the expense of the chiller itself.

On my 55g, I used a Mag 9.5 as my return pump and it was too much flow. The overflow couldn't keep up.

If you want a pump for a closed loop with a ton of flow using the manifold system, I would consider the Sequence Dart. It is rated 3600gph at 0 head and uses 160w of power. The Mag 24 uses 265w of power by comparison, and isn't rated to be used externally anyway.
