My Puristika is decommissioned at the moment, I checked my notes, but I didnāt note down the flow rateā¦I donāt remember it being especially slow. When I next run it, I will check the flow rate. The only caveat, my machine was one of the 3 prototypes built about 2 years before they launched. So it might be different. I believe mine has a standard Ulka pump. It has a green ulka label on the other side and I believe is probably an EX5.
The only possibility is, perhaps they used a 0.5mm gicleur, which might slow things down.
