What happens when an open centrifugal pump is "Dead-headed"?

A centrifugal pump is 'dead-headed' when it is operated without an open discharge outlet. Contrary to what one might assume, centrifugal pumps cannot be stalled if water flow is cut off. Very little horsepower input is required in order to spin the impeller with no water flow, so if the pump is driven by a hydraulic motor, the input hydraulic pressure will be low and the pump will not stall, instead continuing to spin the same volume of water as it would during normal operation. With no outlet, the rotational energy of the shaft and impeller is converted into heat; eventually, the water will boil inside the volute, causing severe damage over time.
