I have a Gould 3656 pump - 16BF1S2AO. On the tag, it shows that it has an 8" impeller and the size is 3 x 4-8. It is outfitted with a 50 HP 3555 RPM motor. I can find no curves for this pump in the 3656 pump specifications.
The curve for a 3 x 4-7 shows flows between 300 and 500 GPM. What can I expect for the 3 x 4-8 with a 50 HP motor?
