RPM’s to keep Flow light green

[DanWC]

Did you get any pressure readings at different speeds?

Yes I did! 1900 RPM’s I was at 5 PSI, 2200 was 5.5 and 2800 was 10.5. Before cleaning, PSI was 10 higher at 2800 than after cleaning.

Definitely a lot better.

I suspect that you could probably go to 1,400 RPM and the cell would probably work.

I would estimate the System curve to be the blue line with a clean filter.

The Operating point should be where the System Curve intersects the Pump Performance Curve at the speed you are running.

At 1,900 RPM, I get about 47 GPM. 2,200 RPM = 54 GPM. 2,800 RPM = 70 GPM.

1,400 RPM should be about 35 GPM. 1,600 RPM = 40 GPM.
