They develop if one part of the fluid flows notably faster than the other, a situation which occurs in areas of flow separation or when two fluids with different flow velocities meet.

What is a Vortex Pump? - EDDY Pump OEM

The Eddy Pump is very similar to a recessed impeller (vortex) pump but with a very distinct difference. It really focuses on inducing a vortex down the inlet to move the fluids, whereas a vortex pump only induces its vortex in the pump casing. To understand this difference, it is important to look directly at the original Eddy Pump
