Yeah, that was my thought too. That being the case it should provide consistent pressure. (There's a reason they're used for pumping stuff like blood )
I have one of those diaphragm pumps usually used for caravan booster pump, it works fine to boost pressure but tends to generate pulsation during espresso extraction, i am interested to find out if the flojet uses a rotary set up to boost pressure without the pressure pulse please let us know when you do a wet run
I have an older model of the flojet which I used for about 2 1/2 years to run my La Scala Carmen 1 group machine whilst living in the UK and initially when I moved back to Australia. The only issue was on changing over the bottle, with a little air getting into the pump. I had to disconnect the line from the machine and run through a little water to get out any airlock. In the end I simply cut a hole in the top of the bottle the pump was in and refilled through the hole so the bottle never emptied.
