    Elevation field on pumps

    What is the elevation field under the pumps supposed to represent? Assuming the c/l of the impeller when I am modeling.

    The elevation value of the pump is used to calculate certain output values and for pressure control on the pumps when needed. Typically people will assign the centerline elevation of the pumps to them. However. for certain pumps like vertical turbine pumps, there may be a large difference between the suction elevation and the discharge elevation of the pump, so it really has more to do with what elevation do you wish to see output results based on as the modeler (as Pressure = (Head (ft) - Elevation (ft))/ 2.31 ft/psi. So choose the elevation that makes the most sense to you in terms of pump controls or pressure values calculated.

    But in most cases the centerline of the pump discharge is often the most useful for most modeling operations to use as the pump elevation.
