Claim:
A vortex-generating nozzle-end ring comprising: a replaceable vortex-generating nozzle-end ring to enhance mixing of liquids or gases in a pump, the replaceable vortex-generating nozzle-end ring including: a body having an outer periphery and an aperture disposed through the body, the aperture defining an inner periphery of the body, the aperture being a polygonal cross-sectional shape, the body being adaptable to the end of a nozzle to cause low pressure fluid entering the nozzle to exit out of the nozzle to flow as a vortex swirl with increased and high turbulent intensity, the vortex swirl, created by the body, having streamwise vortices on an outer periphery of the jet emanating from the nozzle; and at least two tabs extending from the inner periphery radially inwardly toward the center of the aperture, a first tab of the at least two tabs being diametrically opposed to a second tab of the at least two tabs, each tab of the at least two tabs being non-porous and having a solid surface; wherein each tab of the at least two tabs is selected from the group consisting of tapered prism-shaped, tapered pyramid-shaped, and tapered triangular prism-shaped, the apex of which extend substantially toward the center of the aperture.
