Vortex circulation pumps

Vortex

— pumps of this type, as the name implies, use vortices for operation — in this case, those that arise on the blades of the impeller. The main advantages of vortex pumps are high pressure and uniform performance specs, which are practically independent of changes in resistance in the line. On the other hand, they are more sensitive to solid particles in water than centrifugal ones, have lower efficiency, and are also more expensive.
