A pump is a device that moves fluids like liquids or gases by mechanical action, typically converted from electrical energy into Hydraulic energy. Mechanical pumps serve in a wide range of applications such as pumping water from wells, pond filtering, and aeration, in the car industry for water-cooling and fuel injection, in the energy industry for pumping oil and natural gas, or for operating cooling towers and other components of heating, ventilation and air conditioning systems.
There are so many kinds of liquids onboard ships, moving inside various types of machinery and systems to cool, lubricate, and be used as a fuel as well. Marine pumps are an integral part of the ship due to the various fluids that need to be transferred from machinery to machinery. These fluids are moved around the ship mainly by different types of marine pumps, which can be determined by the power supply on a ship. All the systems onboard the ship, require fully functional and viable marine pumps and pumping systems to run the vessel operations without any disturbance.
There are various types of pumps available that are used for different pump technology, such as seawater, fresh water, fuel, and oil. They are however reasonably distinguished depending on the required pressure, flow rate, and compatible construction such as:
