Tuthill Corporation / Vacuum & Blower Systems Booster Liquid Ring Vacuum Systems

Booster-Liquid Ring Vacuum Systems extend the capabilities of the liquid ring vacuum pump by adding a vacuum booster at the inlet of the liquid ring vacuum pump. The booster supercharges the vacuum pump and reduces the pressure on the inlet side of the booster. Flow ranges extend to approximately 2000 CFM (3400 m³/h) with vacuum levels approaching range of 1-10 Torr (1.3-13 mbar). Principle of Operation: The mechanical booster, a lobe-type pump, handles large volumes of gas over relatively small differential pressures. Thus, smaller liquid ring pumps may be employed efficiently on high-gas volumes. Two figure eight-shaped rotors, statically and dynamically balanced, counter-rotate and compress the process stream by trapping it between the rotors and the pump housing. When the vacuum created by the liquid ring pump reaches a predetermined level, the booster automatically cuts in. Cut-in pressures may be adjusted for maximum energy savings.
