Right, it's pretty similar to my system. Coolant going into heat reservoir. Thanks for sharing your experience.

Is it possible to "guess" the flow/pressure just knowing the RPM and supplied power ?

I read his post a bit too fast, missed the "typically". The context of my post was pretty darn specific.

Cold water to a boiler. When you do the coffee shot, there's a variation of the restriction. The goal is also to push with higher pressure initially (preinfusion), then lower during the infusion.

That's not correct.

The machine I have is quite customizable and cheap. Users are installing pressure sensor. I was wondering if I could skip the pressure sensor which is used as a feedback to modulate the pump current, just by knowing what the pump's RMP/current is.

Thanks, you basically answered it. Just out of curiosity, why is it so variable? Shouldn't you expect power and RPM a direct measurement? For the sake of knowledge ;)
