If has the single 1" drain fitting it should be rated in the neighborhood of 600 gph.
My Oceanic 70 came with 2 holes drilled for 1" bulkheads. The 1 is for the drain and the other is the return. It came with 3 bulkhead fittings, a 1", a 3/4" and a universal which was a 1" bulkhead casing with a 3/4" hole. That is the one you need as the 3/4" is too small for the hole and will leak.
Now to get more flow, I think you can use both holes as drains and just hang your returns on the back of the tank. But you really don't want more than 5-7x turnover going through your sump anyway.
