Unlike other gas ejectors, gas jet vacuum ejectors for liquid ring pumps use air at atmospheric pressure as the driving fluid.
They allow the pump to avoid the unpleasant phenomenon of cavitation, solving the noise problem and preserving its integrity to guarantee long-lasting operation.
Ejectors are compact: they are normally installed on the pump’s suction connection; having no moving parts, they require no maintenance, and since they operate on air at atmospheric pressure, they have no energy impact.
The performance of the ejectors is closely related to the efficiency of the liquid ring vacuum pump.
The degree of vacuum produced by the liquid ring pump depends on the vapour pressure and temperature of the operating liquid (normally water is used).
