Marine pumps refer to various pumps for ships that meet the requirements of ship regulations and ship technical conditions. They are often used to transport various liquids such as sea water, fresh water, sewage, lubricating oil and fuel oil on ships.

Marine pumps are widely used in modern ships. Generally speaking, a diesel-powered cargo ship requires 36-50 pumps of various types, which account for 20%-30% of the total marine machinery and equipment.

1.Marine pumps are widely used in modern ships. According to their different uses, they can be divided into

2.General purpose pumps for ships. There are bilge water pumps, ballast water pumps, fire pumps, daily fresh water pumps, daily sea water pumps, hot water circulating pumps; and general pumps that double as ballast, fire fighting, and bilge water pumps.

5.Pneumatic high-pressure pumps and manual hydraulic pumps belong to the supporting hydraulic pumps for hydraulic tools of diesel engines. Provide driving power for hydraulic tools
