Inlet: The operating medium (liquid) enters under pressure, and travels through the Jet Nozzle into the suction chamber. The nozzle converts the pressure of the operating medium into a high velocity stream, which passes from the discharge side of the inlet nozzle.

Suction: The pumping action begins when materials in the suction chamber are entrained by the high velocity stream emerging from the inlet nozzle, lowering the pressure in the suction chamber. The resulting action causes the liquid in the suction chamber to flow toward the discharge.

Discharge: The mixed materials from the suction blends with the operating medium and acquires part of its energy in the diffusion section of the eductor. The velocity of the mixture is converted to a pressure greater than the suction pressure, but lower than the operating medium pressure.
