Water Jet Ejector is an apparatus is used in creating Vacuum wherein the motive fluid into (water) is pumped at high pressure to achieve the enhance velocities and thereby negative pressure is generated due to compression of air molecules in the discharge direction and thereby the vacuum is maintained at the suction which is connected to the mixing chamber.

These equipments is very ideal where the condensable load are high. Due to the high pressure of fluid the better condensation is possible and the load gets reduced to minimum level. The ultimate achievable vacuum of Water Jet Ejector depends mainly on the temperature of motive fluid and the temperature of incoming gases.
