The shut-off head of a centrifugal pump refers to the maximum head (pressure) that the pump can generate when operating at zero flow, essentially when the pump is blocked or not pumping any fluid. It's a critical parameter in pump selection and system design, as it determines the pump's ability to overcome static head and lift fluids to a certain height. To calculate the shut-off head of a centrifugal pump, you typically use the pump's performance curve, which plots head (pressure) against flow
