![]() Operating Principles of EDDY Pump: How is it Different from Vortex Pump? The efficiency will remain similar over the life of the pump. They also wear much better, due to loose tolerances and vortex induction as the driving force. They also vibrate much less since they do not induce pulsating pressures. The vortex impeller design is non-clogging, but this comes at the cost of low efficiency (up to 50%). The rotors are also recessed for solids clearance, although at some cost to the pump efficiency. Vortex formations are dependent on fluid properties like density and viscosity. This requires a very powerful pumping action with high horsepower. To create an efficient flow with the suspended particles, it is essential to generate a sufficiently powerful vortex to induce the suction of the solid particles. Since the rotor is positioned farther back, it allows for solids and even gasses to pass without direct contact with the rotor. Vortex motion may or may not be created by pressure differences of a fluid-solid mixture. The fluid flows into the volute and out through discharge. The pump creates a circular churning motion around an axis to create suction. Operating Principles of Vortex Pump ManufacturersĪ vortex pump (also called a vortex impeller) is based on the principle of creating a vortex flow with a recessed impeller that is positioned away from the path of the liquid.
