Vortex Pump Features
Brass impeller with crossed vanes. The blades of the impeller swirl the water in the pump chamber, forming a chaotic movement with the creation of a large number of whirls (hence the name – vortex). Water streams, colliding one with another, rush to the point of least resistance – the outlet pipe.
