What is a marine pump?

A marine pump is a machine on a ship that is used to increase the pressure or position of liquid and liquid materials. It is generally necessary to use a pump to transport liquid to a higher position, a longer distance, and a higher pressure. The pump can also be used to generate high pressure liquid for hydraulic transmission. The pump is driven by an electric motor or other prime mover. The characteristics of the marine pump are: the pump is required to be cavitation due to the fluctuation of the suction liquid surface when the ship is swaying and tilting; in order to reduce the occupied area of the pump and to facilitate maintenance, the vertical structure is generally adopted; the flow passage member is made of bronze, Made of materials such as brass or stainless steel to minimize corrosion.

Marine pumps have a wide range of applications in modern ships. Generally speaking, a diesel-powered cargo ship requires 36 to 50 pumps of various types, which accounts for 20% to 30% of the total amount of marine machinery and equipment.
