In order to pump seawater, fresh water, fuel oil, lubricating oil and other liquids on ships, a certain number and different types of pumps are needed.Generally, it is necessary to install bilge pumps, fuel oil and lubricating oil transfer pumps, boiler feed pumps, cooling pumps, ballast pumps, sanitary pumps and other major oil pumps and pumps in the engine room.
