What size cpvc?

[Jimbo C]

I'm moving my sump downstairs. My idea was to use 3/4 cpvc drain and return, only because I can get all the fittings and valves for free. Is this size pipe adequate for a nine foot drop and head? If not how and what size should I go with?

I'd use this pump, the outlet is 3/4" so you'd be ok.

But if you look at this 600 gph overflow :

The bulkhead size is 1"
