Vortex deep well pumps

Vortex

— pumps that work by creating vortices on the impeller blades. This principle of operation is notable for its high pressure and good performance, even with significant resistance in the water supply system (which distinguishes vortex pumps from centrifugal ones). The main disadvantage of such units is their low efficiency, which can significantly decrease if contaminants enter the impeller. Therefore, such pumps must be connected with a filter.
