Operating pressure: 8 to 80 mbar
Suction volume flow: 5 to 1050 m³/h
CONSTRUCTION TYPE
Sterling SIHI gas ejectors are simple and sturdy vacuum
gas ejectors with following particular characteristics:
Adaptable to different operating conditions by adequate
material selection
Simple installation into the suction line of liquid ring
vacuum pumps
Low noise service which is free of maintenance and
deficient in vibration
APPLICATION
Sterling SIHI gas ejectors extend the operating range of
Sterling SIHI liquid ring vacuum pumps so that lower
absolute pressures become possible (to 8 mbar).
Field of application are e.g.:
Chemistry and pharmacy for distilling and degassing
Electric industry for impregnation and drying
Plastics industry for degassing etc.
The gases which are to be handled may be vapour
saturated or aggressive. Sterling 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 immenent 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.

NOTE
The characteristics of the suction volume flow of the gas
ejectors depend on essentially on the suction capacity of
the liquid ring vacuum pump and therefore on the vapour
pressure ant temperature of the service liquid used.
To meet with the different conditions, we offer 2
construction series.
Type: A B
Service liquid: water to 15°C water to 30°C
Suction pressure: 8 . . . 40 mbar 20 . . . 80 mbar
POLLUTION CONTROLL: To reduce the exhaust blast the
motive gas can be removed from the separator.
The standard combinations described in this catalogue list
are optimal in view of suction volume flow, power
absorption and service charges. Other combinations of gas
ejectors and liquid ring vacuum pumps can be
applied. Details on request.
