HA715, HA815

These impellers are the latest generation of our high efficiency hydrofoils which reduce operating costs and result in smaller more cost effective drives. They are the most widely used impeller for low to medium viscosity blending and solids in suspension applications. Their strong axial flow allows for sufficient off bottom spacing to ensure the impeller does not become bogged in settled solids should the mixer be shut off. Up pumping variations are also used in combination with other impellers to maintain uniform mixing throughout the vessel at lower power inputs. Modifications can be made to the HA715 to ensure that it generates sufficient flow rates even when the impeller is required to be in very close proximity to the tank bottom.
