INSTALLING LIQUID-RING VACUUM PUMPS

In fact, liquid-ring vacuum pumps in any piping arrangement should not be started with a full casing of seal liquid. Thus, provi-sions are normally made to drain the pumps in the event they become flooded. These provisions may vary somewhat from one manufacturer to another.

Proper Piping for Vacuum Systems - graham-mfg

As vacuum is produced, the water rises in the tailpipe to the height induced by the vacuum, minus the barometric pressure. If there is insufficient hotwell area present, the seal will be broken and air drawn into the tailpipe, affecting the performance of vac- uum-producing equipment and the process.

MT: Troubleshooting Low Vacuum Levels | NASH

Low vacuum can be caused when the vacuum level exceeds the limits of a vacuum pre-separator, seal leg, or seal tank system in systems that have such equipment. High vacuum levels can draw all of the water out of the seal tank, leaving the seal piping open to the atmosphere. Vacuum pre-separators operate with either a barometric seal leg (pipe) or with a low NPSH removal pump. The seal leg is
