Eductors are used to agitate liquids, dissolve powdered solids into liquids, and effectively mix two or more liquids. These devices can be utilized as an alternative to conventional mechanical agitators. The operating principle is as follows: Liquid is drawn from the tank through a centrifugal pump and supplied to the eductor. Inside the motive nozzle, the liquid's pressure energy is converted to kinetic energy, forming a high-velocity flow at the nozzle outlet that draws in surrounding liquid. The drawn fluid is uniformly mixed with the motive fluid in the diffuser and discharged, with mixing performance further enhanced by the drag force generated during this process.
