The flow rate regarding pumps and systems refers to the amount of liquid or gas a pump can deliver per unit of time. It is usually measured in units such as litres per minute (l/min), cubic metres per hour (m³/h) or gallons per minute (GPM), depending on regional standards.
The flow rate is a crucial parameter that determines how efficiently a pump works and fits into a system. It depends on various factors, such as the pump design, the diameter of the conductors and pipes, the pressure, the viscosity grade of the liquid to be pumped and other system-related properties. In practice, a higher flow rate means the pump can move more liquid or gas per unit of time. It is essential to size the flow rate carefully to ensure it meets the system's requirements.
