What is one function of a vacuum return pump in a condensate system?

In a condensate system, one primary function of a vacuum return pump is to push condensate back to the boiler or feed tank. This is critical in maintaining an efficient steam system, as it helps to recover and reuse the condensate formed when steam cools and condenses. By transporting this liquid back to the boiler or feed tank, the system ensures that valuable water and heat energy are not wasted, thus improving overall efficiency and reducing the need for fresh water input.

In addition, returning condensate to the boiler allows for proper maintenance of water levels, which is essential for safe and efficient boiler operation. This function directly contributes to energy conservation and effective water management within the steam system, underscoring the importance of the vacuum return pump in a condensate system.
