SIHI gas ejectors are used wherever the vacuum attainable by a liquid ring vacuum pump is not sufficient and where danger of running in cavitation is imminent for the liquid ring vacuum pump. Even if the suction side of the ejector is closed, the liquid ring vacuum pump is protected against cavitation.

Design

SIHI Gas ejectors are simple and sturdy vacuum gas ejectors with following particular characteristics as adaptable to different operating conditions by adequate material selection, simple installation into the suction line of liquid ring vacuum pumps and low noise service, which is free of maintenance and deficient in vibration.

Application

Gas ejectors extend the operating range of liquid ring vacuum pumps so that lower absolute pressures become possible (to 8 mbar). Field of application are chemistry and pharmacy (distilling and degassing), electric industry (impregnation and drying), plastics industry (degassing) etc.
The gases that are to be handled may be vapour saturated or aggressive.

Suction volume flow: up to 1,500 m³/h
Suction pressure: 4 up to 80 mbar
Product Series: GEV / GOV / GPV
