Heat Exchanger Used to remove heat from the recirculated service liquid.
Atmospheric Used to provide a suction pressure lower than the pump is
Air Ejector capable of when operating alone. It may be added to a two stage
pump to provide an inlet pressure as low as 3 mm HgA. The
operation of the air ejector is similar to that of a steam ejector.
Atmospheric air or recycled gas from the discharge separator is
used as the motive force for compressing the process gas from
the system design pressure up to the inlet pressure of the pump.
To enhance pumping capacity at a higher suction pressure, an
optional motive air shut-off valve or by-pass valve can be added.
