SICCE SYNCRA pump

[oupulino]

I need help figuring out which model of Syncra pump I have to use in my future sump.PVC pipe going to be 4' long from sump to the tank.I'm thinking of 2 models:
SICCE SYNCRA 2.0 PUMP 568GPH
SICCE SYNCRA 3.0 PUMP 714GPH
I have Life Reef overflow box flow rates up to 600 gph.
My return is 4' high so has to loose sam's gph
Are this pumps are good or just standart pumps
Let me know your recommendation.Thanks

I just happen to have a Sicce Syncra box sitting next to me... at 4ft head you're looking at:

Around 200-220GPH w/ Syncra 2.0
and
Around 520GPH w/ Syncra 3.0

These are rough estimates from looking at the graph on the box (mind you it's 2:30am here and I don't have my glasses). My personal experience with Sicce Syncra pumps has not been stellar but I was also sold one that was way too small for my tank. I replaced my Syncra 2.0 with a Mag 9.5 (950GPH) on my 75gal. The syncra pump now serves to circulate fresh RO water as I mix salt, and I'm also using it to feed fresh SW from my mixing container to my DT. It works great for this purpose so I'd say they're okay pumps if you pick up the right size!

If it was me, I would go with the Syncra 3.0 and if necessary divert extra flow elsewhere (back to your sump) but I don't think your box will have trouble handling that. You could also get a ball or gate valve to reduce flow... I always like having too much than not enough. With my Mag9.5 I had enough flow that I T'd off it to drive my GFO reactor.
