20220016584 · 2022-01-20 ·

An eductor for mixing a diluent with a chemical. The educator includes an eductor body having a nozzle section with an inlet portion and an air gap portion, the inlet portion configured to couple to a diluent source and the air gap portion open to the atmosphere, and a venturi section coupled to the nozzle section. The nozzle section and venturi section may be connected by a swivel joint. The venturi section includes a venturi configured to couple to a chemical source for drawing chemical into the venturi with the flow of diluent through the venturi. A nozzle assembly positioned in the nozzle section of the eductor body. The nozzle assembly is selected from a plurality of nozzle assemblies each configured to be positioned in the nozzle section and operable with the eductor body, and each corresponding to a different volume flow rate through the eductor.
