Eductors – Jet Pumps
Eductor Body — The Suction and Motive Connections
Manufactured to specified finish and concentricity, assuring performance vastly superior to that of competitive units.
Eductors operate on the basic principles of flow dynamics. This involves taking a high pressure motive stream and accelerating it through a tapered nozzle to increase the velocity of the fluid. Gas Motives are compressible fluids and are put through a converging-diverging nozzle. The gas can exceed the speed of sound. This fluid is then carried on through a secondary chamber where the friction between the molecules of it and a secondary gas (generally referred to as the suction fluid) causes this secondary gas to be pumped. These fluids are intimately mixed together and discharged from the eductor.

Connection Types
There are three connections common to all venturi eductors.
Motive Connection
Suction Connection
Discharge Connection

Providing a smooth flow path is critical to optimum eductor performance. As a result of this feature, the motive fluid achieves more velocity through the eductor body, and this means more energy is used for pick-up of the suction fluid. Also, better flow paths in the diverging section of the eductor allow it to achieve better discharge pressures.
Competitive units are weak and subject to breakage during installation. All NCI units have wrench flats to prevent damage.
