What type of pump is used to increase pressure after atmospheric storage?

The appropriate type of pump used to increase pressure after atmospheric storage is known as a booster pump. These pumps are specifically designed to raise the pressure of water or other liquids, making them suitable for applications that require higher pressure than what is available from atmospheric storage alone. Booster pumps function effectively in enhancing the water pressure for distribution within a plumbing system, ensuring consistent flow rates to various fixtures or appliances throughout the system.

Repressurization pumps, while they may seem relevant, typically refer to a specific type of pump configured to bring pressure back to a specified level within a designated system rather than focusing on the transition from atmospheric conditions to elevated pressure.

Transfer pumps are primarily utilized for moving liquids from one location to another, such as from one tank to another, but do not primarily focus on creating pressure increases.

Purge pumps are used to remove unwanted liquids, gases, or solids from a system, usually for the purpose of maintenance or to prepare a system for servicing, rather than to increase pressure effectively.

Hence, the booster pump is correctly identified, as it is tailored to fulfill the requirement of increasing pressure in systems requiring it after storage.
