Question 1286 Deck General

The correct answer is C) incomplete priming. Explanation: Centrifugal cargo pumps require proper priming to establish suction and begin discharging cargo. If the pump is not fully primed, it will lose suction and the flow will be interrupted. This is the most likely cause of the pump losing suction in this scenario. The other options are incorrect because: A) the pump running backwards would not be the cause, as that would prevent the pump from working at all; and B) the discharge head being too high may reduce the pump's performance, but would not directly cause a loss of suction.
