Which type of pump is used to increase water pressure or flow in a pipeline?

A booster pump is specifically designed to increase the pressure within a water system, allowing water to flow more effectively through pipelines, especially in situations where gravity alone is insufficient to move the water to the desired location. This type of pump is essential in applications that require the movement of water over long distances or to higher elevations, as it compensates for pressure losses that occur due to friction and elevation changes in the system.

Gravity pumps are reliant on gravitational forces to move water, making them suitable for situations where water can flow downhill, but they have no capacity to increase pressure. Submersible pumps are designed to operate underwater and are often used for tasks like pumping water from wells or keeping reservoirs clear, focusing on getting water out rather than pressurizing it. Diaphragm pumps work by utilizing a diaphragm to create pressure but are typically utilized for specific applications, such as transferring liquids or viscous materials, rather than general water pressure boosting in pipeline systems.
