Pump selection for parallel pump control is critical in determining the desired total system output. Check pump curves to make sure that the number of pumps, flow, head, and multi set points are adequate for your system needs. Head pressure may not remain constant in some cases, as the flow is increased to multiple pumps. Courtesy: Crane Pumps & Systems.
