Adding a second mechanical booster extends system operation to vacuum levels as low as 2.0 mm Hg Abs. Like single-booster systems, the boosters are not energized until vacuum reaches a preset level. Smaller boosters with larger motors are used for booster operation over the full pressure range. By adjusting the cut-in pressures for both booster stages, the system can be tuned for maximum efficiency and energy savings with a wide range of process stream gases.
Principle of Operation
Booster-Booster-Liquid Ring Vacuum Systems take the concept of supercharging a liquid ring vacuum pump a step further by adding a second vacuum booster at the inlet of the liquid ring vacuum pump. This increases flow as high as 6000-8000 CFM (10200-13600 m³/h), with vacuum levels in the range of 2 Torr. Cut-in points for the boosters can be adjusted to optimize system efficiency and energy savings.
