Unlike other types of gas ejectors, air jet vacuum ejectors for liquid ring vacuum pump, use atmospheric air pressure as motive fluid.
These ejectors are used to increase the vacuum level of the liquid ring vacuum pump, preventing it from cavitation even if the suction port of the ejector is closed, thus ensuring its integrity and long- lasting use.
Ejectors are usually installed on the suction connection of the pump; they are simple and sturdy and by selecting suitable material, they are adaptable to different operating conditions.
Since they have no moving parts, they do not require maintenance and operate at atmospheric pressure, without energy impact.
