English term or phrase:vapour-bound
The pressure on the suction side of the pump could drop below the vapour pressure of the liquid. This drop may be caused by insufficient head, high suction lift, excessive friction head, or high liquid temperature. If the liquid flashes, the formed vapour can partially or completely stop liquid flow into the pump. The pump is then said to be vapour-bound or vapour-locked.
