Flow rate is a critical parameter in pump selection, directly influencing the production capacity and overall conveying efficiency of the system. During the design phase, engineering institutes typically calculate the normal, minimum, and maximum flow rates to ensure proper pump performance under various operating conditions. When selecting a pump, the normal flow rate is usually based on the maximum expected flow, as it ensures the pump can handle peak demands without failure. However, if the maximum flow rate is not clearly defined or unavailable, the normal flow rate may be used as a reference for the maximum. This approach helps avoid under-sizing the pump, which could lead to inefficiency or system downtime. Proper flow rate evaluation is essential for optimizing both energy consumption and operational reliability. It also plays a key role in determining the appropriate pump type, size, and configuration. Engineers must carefully analyze process requirements and flow variations to make an informed decision that supports long-term system performance and cost-effectiveness.
