During emergency dewatering operations aboard naval vessels, damage control teams employ the portable P-100 diesel-driven centrifugal pump. The pump is designed to deliver 100 gallons per minute at a discharge pressure of 83 psi when operating at a 20-foot suction lift. To prevent engine overheating during continuous operation, the exhaust system utilizes a direct water-injection cooling loop. Operators must clean the intake strainer every four hours of continuous pumping to prevent debris from clogging the impeller housing.
