Liquid Jet Exhausters

E700 Series

The liquid jet exhauster is used to suck, entrain and pump out gases from its source point utilizing a high pressure motive liquid such as water or other liquid. Motive liquid is discharged at a high velocity through a specialized nozzle and sprayed through body and venturi throat & tail. 

Specially designed nozzle creates a full cone spray. The liquid spray covers and seals the exhauster throat and fills the tail portion of the exhauster to create effective self priming action.  The nozzle converts the pressure energy of the motive liquid into a high velocity spray.  When the sucked gas is mixed with the high velocity motive liquid, momentum of the motive liquid is transferred to the suction gas. This transfer in momentum creates vacuum. 

The liquid & gas stream enters the exhauster throat and passes through tail where the velocity energy is converted into an intermediate discharge pressure.  Lower the temperature or lower the vapour pressure of motive liquid a higher vacuum level can be obtained.

MATERIAL OF CONSTRUCTION

Various metals & plastics can be employed for exhauster body & nozzle depending on service conditions, fluid and its properties.  Typically exhausters can be supplied in cast-iron, carbon steel, stainless steel, titanium, Hastalloy, Monel metals.  In plastics PVC, CPVC, Teflon and  Polypropylene can be supplied.

END CONNECTIONS
