Name two pump types commonly used in dewatering and their general function.

• A. Cooling pump circulates coolant
• B. Bilge pump removes water from bilges; Fire pump provides water to firefighting systems
• C. Waste pump handles sewage
• D. Sludge pump handles mud

Answer: (B)

In dewatering, you want equipment that can remove water quickly from spaces and, in emergencies, provide a strong water supply for firefighting needs. The bilge pump is designed to pull water out of the bilges—the lowest areas of the ship—preventing accumulation that could threaten buoyancy. The fire pump is built to deliver large volumes of water to firefighting systems, ensuring adequate pressure and flow to hoses and sprinkler or deluge systems. Together, these two cover the practical dewatering role: removing incidental water and supplying a reliable water source for control of fires. Other pumps, like cooling pumps, waste pumps, or sludge pumps, address different tasks and aren’t standard dewatering tools.
