What is pump head?

Pump head, also known as total dynamic head (TDH), is a measurement of the maximum height that a pump can lift water vertically. It is calculated by adding the vertical lift, friction losses, and pressure losses in a pumping system.

Pump head is an important factor to consider when selecting a pump for a specific application, as it determines the pump's ability to overcome resistance and deliver water at the required pressure. The pump head requirement can vary depending on the distance water needs to be pumped, the type of piping system used, and the flow rate of water.

It is important to ensure that the pump selected has enough head to meet the requirements of the system, as insufficient head can lead to issues such as cavitation, reduced flow rates, and inefficient operation. Pump head can be calculated using specific formulas based on the system's characteristics and requirements.
