Understanding pump curves #3: centrifugal pumps in parallel

WebJun 15, 2024 · Match pumps properly. Ideally, a parallel system should consist of pumps with similar total head at zero flow (shutoff) and their best efficiency flows. This way, multiple pumps will split the load evenly when running. If a system uses pumps with dissimilar heads in parallel, the pump with the higher head may wind up doing all the work. WebMay 26, 2024 · Since the operating point will be where the pump and system curves intersect, we can set the two equations equal and solve for flow rate.
