When pumps are connected in parallel, they operate simultaneously with their inlets receiving the same fluid source and their outlets combined. This configuration results in an increased overall flow rate while maintaining the same head pressure as a single pump. By distributing the workload across multiple pumps, parallel pumping ensures efficient operation and redundancy in systems where higher flow rates are required. This setup is commonly utilized in various applications, including large-scale water distribution networks, industrial processes, and HVAC systems, where maximizing flow capacity is essential.
