Eductor

PRINCIPLE OF OPERATION

The liquid jet eductor enables to lift, entrain and pump out a low pressure liquid utilizing a high pressure motive liquid. The high pressure motive liquid enters the motive chamber of the eductor through a converging motive nozzle. At the eductor nozzle, the pressure energy of the motive liquid is converted into a high velocity jet. The momentum present in the motive liquid is transferred to the suction liquid thereby enabling a LIFT, entrainment & mixing. Thus the high velocity motive liquid mixes with the suction liquid and the combined streams then enter the venturi throat and diffuser section where the mixing continues. Velocity energy is converted to a pressure intermediate to the suction and motive pressure.
