What is the main purpose of a pump?

The main purpose of a pump is to move a liquid from one place to another. Pumps are designed to create a pressure differential that allows fluids to flow through a piping system, transferring liquids to various locations, such as from a storage tank to machinery or from one compartment of a vessel to another. This function is crucial in many applications, including marine engineering, where proper fluid movement is essential for operational efficiency and safety.

While some pumps can be involved in heating or cooling systems, their primary role remains the facilitation of liquid movement. Heating, cooling, and filtration can be secondary processes or functions dependent on the fluid system's design but do not define the fundamental purpose of a pump.
