Agitator Mixer
Behpoo agitator mixers keep liquids, slurries and suspensions homogeneous in drums, IBCs and tanks. Seven impeller types cover everything from water-thin solvents to high-viscosity pastes.
An agitator mixer drives an impeller on a shaft to circulate the contents of a vessel — re-suspending settled solids, homogenising layers, dispersing powder into liquid or holding an emulsion stable.

Impeller choice is the whole decision. Axial impellers — marine propeller, hydrofoil, folding — pump the fluid up and down the vessel with low shear, which is what most blending and suspension duties need. Radial impellers — Rushton turbine, dispersion disc — create an intense shear zone, which is what dispersion, emulsification and gas distribution need.
Mounting is the second decision. On a closed drum, the unit threads into the 2-inch bung and a folding impeller passes through the opening. On an open drum a rim clamp is used; on larger vessels, a stand or lift.
One detail matters more than it looks: a drum has no baffles, so a centrally mounted vertical agitator makes the liquid rotate as a body and mix nothing. Behpoo mounts drum agitators off-centre and angled.
