The 2AM-BG200 bung agitator (also called bung-entering agitator) is a removable agitator that is mounted at the standard 2″ bung opening of closed 200 litre/55 gallon drums. The angled mounting device reduces vortexing and allows for off-center mixing. This design provides a simple means of mounting smaller mixers onto tanks or drums with a bung hole in the cover. The agitator features collapsible (foldable)/expanding blades which allows the insertion and extraction through the standard 2-in bung opening. The working principle of the blades: centrifugal force causes the blades to open. The agitator can be easily customized by adjusting the blade height or by adding additional blades.


Agitator for closed-top standard 55 gallon drums (depending on the country also referred to 200 or 210 liter drums) with 2″ Bung opening in the cover. Low viscosity of the agitated material.


For medium viscosity of max. 2,000 cps the model 4AM-BG200 (1.5 hp/1.12 kW) can be offered.
