The PJT turbine impeller is a radial flow impeller. The impeller blade design matches the shape of the cavity; the special profile edges of the blades help to avoid flow separation. The difference in power consumption between the inflated and non-inflated states is quite small. The overall efficiency of the PJT turbine impeller is much higher than that of gas-dispersing impellers. Impellers for efficient gas dispersion used in gas-liquid reactions and gas suspensions.
