Why Use A Vacuum Pump? - Shipco® Pumps

When the boiler stops making steam, and the steam condenses in the boiler and header, an induced vacuum occurs due to the change in volume between steam and condensate. With a vented boiler feed tank and pumps, atmospheric pressure pushes feedwater from the tank into the boiler and header causing the flooded condition you describe.

Do you know what a vacuum hot water boiler is? - Company

Installing a vacuum pump in steam condensate return system removes the air efficiently out of return piping. This enables the condensate to return more rapidly to the boiler feed unit or condensate vacuum unit. This reduces energy consumption and cuts boiler room operating costs. Performance of heating units can be significantly improved as well.

How to Destroy a Boiler -- Part 3

Pulling A Vacuum. When boilers are designed to operate at very high pressures, they are not designed to operate under even the slightest vacuum. A potential vacuum is created when a boiler is shut down. As the unit cools, the steam condenses and water level drops, which allows the pressure to drop.
