Universal impeller of the next generation

Axi­al­ly con­vey­ing impellers serve a wide range of appli­ca­tions and are there­fore among the most wide­ly used impellers in agi­ta­tion and mix­ing tech­nol­o­gy. The new axi­al Eco­foil-impeller leads to excel­lent process results with dras­ti­cal­ly reduced pow­er demand.
With the Eco­foil impeller, Eka­to is break­ing new ground and offer­ing a stir­rer that is not sub­ject to lim­i­ta­tions relat­ed to tra­di­tion­al man­u­fac­tur­ing tech­nolo­gies. The result­ing free­dom of design allows for high­ly effi­cient axi­al out­flow with strong­ly reduced vor­tex shed­ding using com­plex three-dimen­sion­al geome­tries — curved blade with air­foil pro­file and twist­ing over the radius. This achieves an increase in the cir­cu­la­tion rate of up to 40 % com­pared to con­ven­tion­al axi­al or pitch blade impellers with the same pow­er input. Accord­ing­ly, the process times are short­ened or the mix­ing qual­i­ties improved. Alter­na­tive­ly, sig­nif­i­cant­ly low­er pow­er set­tings are required for the same process results.
The devel­op­ment is based on para­me­ter stud­ies with numer­i­cal flow sim­u­la­tions and has been val­i­dat­ed by exten­sive lab­o­ra­to­ry and pilot exper­i­ments. Nov­el addi­tive man­u­fac­tur­ing meth­ods allow the eco­nom­ic imple­men­ta­tion of com­plex geome­tries in the man­u­fac­ture of agitators.
