I believe the flow rate given was on our small piston pump, measured manually. Th figure on the chart is measured with the shurflo pump. The difference is probably due to the way the pressure is generated. Piston pump has pressure gaps between strokes compared to a diaphragm pump - injects less.

I can measure the 0.3mm 3-scoll and 4-scoll for you tomorrow with the aquatec pump for you just to be sure if the previous chart are calculated ot measured *only apply to the 0.3mm.
