TDH Calculator

Pump Selection Made Simple
Total Dynamic Head (TDH) is the measurement used to determine the right submersible or surface pump for your setup. Our free TDH Calculator factors in elevation, pipe length, and friction loss to give you an accurate result—so you can choose the correct pump with confidence.
Simply refer to the diagram below and input your measurements in the calculator. The result will be your TDH.
Match your TDH result to our pump flowcharts, or contact our team with your result and one of our experts will recommend the right pump for your setup.
