What combination of devices is designed to discharge air and pump water?

The combination of a vacuum pump and a condensate tank is specifically designed to discharge air and pump water. In boiler and steam systems, maintaining a vacuum is important for efficient operation, particularly in condensate return systems.

A vacuum pump removes air and non-condensable gases from the condensate tank, which allows the system to maintain a lower pressure that aids in the efficient return of condensate to the boiler. As the air is eliminated from the system, it minimizes the chances of steam leaks and helps in reducing the energy needed for the steam process.

The condensate tank, on the other hand, collects the water that results from the condensing steam. When the vacuum pump operates, it ensures that the condensate can flow back to the boiler effectively without air disrupting the flow, which enhances system efficiency and performance. This combination ensures a smooth operation, preventing issues that can arise due to trapped air in the system and optimizing the water return process.

Other combinations of devices, such as a condensate tank and pump, may focus solely on water handling without emphasizing the need to remove air. Similarly, options involving an expansion tank or valving mechanisms serve different purposes related to pressure regulation and liquid expansion but do not specifically target both air discharge and water pumping
