    For closed systems: Pump head = the sum of all friction pressure drops

    Where:

    Friction pressure drop = piping pressure drop + terminal unit pressure drop + source unit pressure drop* + valve pressure drop + accessories pressure drop. -- Source
    You will also find detailed instructions describing the process of calculating the correct pump head for your situation.
