TDH is a combination of two components – Static Head and Friction Head – and is expressed in feet. Static head is the actual vertical distance measured from the minimum water level in the basin to the highest point in the discharge piping. Friction head is the additional head created in the discharge system due to resistance to flow within its components. Liberty has charts available to calculate TDH. Please contact Liberty’s customer service department for proper pump sizing.
