Moving from immersion to counterflow Pump needed ?

[Indiana Red]

This will be the next step as I ramp up my production and switch to better equipment. It just occured to me though,
Can I still be gravity/siphon only and still use one of these?

Yes, I have the same CF I did it for about 4 batches before I moved to a pump. Just like with any siphon just make sure it's lower than your beer and you might have to give it a couple extra pumps.
