A510 /A310,theA200 still has a specific role in applications where a degree of fluidshear is beneficial to the overall process result. A200 For low-to-medium viscosity flow controlled applications. Although superceded by the A340 High efficiencyhydrofoil up-pumping impeller for use in multi-phase mixing.The up-pumping A340 can greatly increase process gains (up to100%).This is accomplished by its gas induction at the surface and its high velocity at the tank wall,which increases heat transfer.There is no practical upper limit for the amount of gas the A340 impeller can handle. > Reassembly of...
