WebMay 22, 2024 · Shut-off Head. In the performance curve for a centrifugal pump the shut-off head is the point on the graph where the flow rate is zero. Shut-off head is the vertical lift in height – usually measured in meters of water column, at which a pump can no longer exert enough pressure to move water. J. R. Lamarsh, Introduction to Nuclear Reactor ... WebSince the centrifugal pump operates on the intersection of the process characteristic curve and the QH curve, the flow rate and head can be predicted by the affinity law along with these two ...
