Marine Pumps include oil pumps and water pumps which used in ships and meet the requirements of ship regulations and marine technical conditions. These pumps are often used to transport various liquids such as sea water, fresh water, sewage, lubricating oil and fuel oil… in ship.

On ships, it is often necessary to transport liquids such as water and oil. For example:

• in order to ensure the safety and sanitation of the ship, the sewage accumulated in the bilge must be regularly discharged outboard;
• the fuel oil should be continuously delivered to the main engine and generator to ensure the continuous operation of the machine;
• the boiler should be supplied with water in time, In order to ensure that the boiler can continuously generate steam;
• in order to ensure the normal operation of the machine, lubricating oil and cooling circulating water must be continuously provided;
• in order to improve the stability of the ship during navigation, it must be completed by transferring ballast tank water;
• In addition, the transfer of cargo oil should be completed on the tanker.

The delivery of these liquids is usually completed by a special equipment – “marine pumps”. So the function of a certain marine pump is to deliver a certain liquid that is required. In this sense, marine pump is a machine that transports liquids.
