Here is one more important data point.

Test run at 3000RPM pump(6000RPM E-Shaft) with the pump lever at the lower stop, which is essentially idle speed.
Flow rate is .047L/hr.

Determining the actual flow rate at a setup requires you to measure the control lever angle, and interpolate the flow rate at 6000RPM E-Shaft speed. Calculate actual flow rate with < observed RPM/6000*flow rate>. You can also calculate the setting of the lever to achieve a predetermined, required flow rate.
