What is the definition of pump head?

The definition of pump head refers to the height to which a pump can raise water. This measurement is crucial because it indicates the maximum vertical distance that the pump can move water when it is operating at a specified flow rate. Pump head is typically measured in feet or meters and is an essential factor in selecting a pump for a particular application.

Understanding pump head is important for several reasons. It helps to determine whether a specific pump is suitable for a given system or application, as it needs to overcome various factors including elevation changes and friction losses in the pipes. If a pump has a high head, it can effectively transport water to higher elevations or through longer distances, making it ideal for applications such as irrigation, water supply, or fire protection systems. The pump head directly impacts the efficiency and performance of the pump, so it is a key dimension that engineers and operators consider when designing and maintaining hydraulic systems.
