Worksite Vortex Pump 1/2 Inch HP- Are based on the principle of creating a vortex flow with a recessed impeller that is positioned away from the path of the liquid - QB60-110V

Operating Principle of the Vortex Pump
Vortex pumps (also called recessed impeller pumps) are based on the principle of creating a vortex flow with a recessed impeller that is positioned away from the path of the liquid. It creates circular churning motion around an axis that creates suction for the fluid to flow into the volute and out through discharge. Vortex motion may or may not be created by pressure differences of a fluid-solid mixture. Since the rotor is positioned farther back it allows for solids and even gasses to pass without direct contact with the rotor.

To create an efficient flow with the suspended particles, it is essential to generate a sufficiently powerful vortex to induce suction of the solid particles. This requires a very powerful pumping action with high horsepower. Vortex formations are dependent on fluid properties like density and viscosity. The rotors are also recessed for solids clearance, although at some cost to the pump efficiency.

The benefit of vortex pumps is that it is a non-clogging design, but this comes at a cost of low efficiency (up to 50%). They also vibrate much less since they do not induce pulsating pressures. They also wear much better, due to loose tolerances and vortex induction as the driving force. The efficiency will remain similar over the life of the pump.
