To achieve the rated capacity of a pump, it must be operated in which position?

Operating a pump in a parallel position allows multiple pumps to work together to increase the flow rate while maintaining constant pressure, which is essential for achieving the rated capacity. When pumps are arranged in parallel, each unit can contribute to the overall output, effectively utilizing the combined capacity of all the pumps involved. This setup is particularly beneficial when higher flow rates are needed, and it ensures that the system can deliver the required volume of water efficiently.

In contrast, running pumps in series usually means that one pump feeds into another, which may increase pressure but does not necessarily enhance flow rate. Although certain applications might require series configurations, they are not suitable for maximizing the flow capacity of a system like parallel setups are. Single operation refers to using one pump, which limits the flow to that pump’s individual capacity. Bypass configurations allow for diversion of flow and do not focus on achieving the rated capacity but rather on maintaining flow during maintenance or operational changes. Thus, to achieve maximum flow capacity, parallel operation is the preferred and most effective method.
