Tank Mixing Eductors, Color : Black

Introduction
Eductor is a device which is used to create vacuum to suck the secondary liquid or gas. The main difference between Eductor and Ejector is that Eductor use water as motive fluid and Ejector use Air or Steam as motive fluid. There are some constructional differences, but the final duty is to create vacuum. Eductor is widely used in industries for number of applications.
Working Principles
Eductor operates in accordance with the well-known Bernoulli equation. A high pressure/low velocity motive fluid is converted into a lower pressure/higher velocity jet through a nozzle. Jetting past a suction connection in the head of the device will entrain a secondary low pressure fluid.
Eductor Sizing
Eductor diameter depends on the volumetric flow rate. The internals of Eductor such as jet nozzle sizing depends on requirement of suction. The other factors also have to be considered i.e. motive fluid pressure, pressure drop and requirement of downstream pressure
