Why Use Vacuum Pumps

The main reasons for having vacuum pumps on low pressure steam condensate return lines are AIR REMOVAL and PRESSURE REDUCTION.. During mild weather when the boiler is on only part-time, the vacuum pump’s main job is to mechanically remove air from the system so we don’t have to use steam pressure to push air out.
