Why are my fixed flow VSP pump(s) providing more flow than I have specified as the flow(Target) in the properties?
Look at the hydraulic grade of the pump(s) vs. the hydraulic grade of the downstream elements.
If the hydraulic grade at the pumps is higher than the downstream hydraulic grade then it means the pumps need to operate at a higher flow rate because the flow could really be transferred by gravity. In many cases the pumps may be showing operating at the zero head point or a near zero head point.
