55-Gallon drum mixer - The Pulsair 5-55 Drum-Stick

Portable top-entry 55-Gallon drum mixing equipment for liquid blending and agitation

Pulsair Systems manufactures the world's best portable 55-gallon drum mixing equipment for drum mixing, blending and agitation. The 5-55 Drum-Stick weights less than ~3 lbs, is easy-to-use and works through the standard fittings in drum lid, so no special tank mounting equipment is required.

The Pulsair 5-55 Drum-Stick can be hand-held, or is self-supporting with the Pulsair bung vent/clamp. The mixer unit also includes a 40" stainless steel probe with a special 2" accumulator plate, filter, regulator and coiled air hose with quick connect.

How it works:

The Pulsair 5-55 Drum-Stick produces powerful, sequentially timed pulses of compressed air or gas to generate large bubbles at the bottom of the 55-gal drum. The rising bubbles create immediate vertical circulation mixing that stirs the liquids in the drum from the bottom up. A small 2" accumulator plate attached to the end of a 40" stainless steel probe sits on the bottom of the drum and introduces the compressed air bubble. The burst of compressed air from underneath the plate scours the bottom and lifts solids and heavier liquids up into the drum. This "bottom-up" vertical mixing process keeps the solids in suspension and the entire liquid contents of the 55 gallon drum in motion at any liquid level.

The Pulsair mixing process works in larger tanks, tote, rail tank cars and much more:

The Pulsair 5-55 Drum-Stick is easily transfered from drum to drum and used without having to remove the drum lid. Multiple tests show that the Pulsair mixing method allows the liquid contents in a 55 gallon drum to be completely mixed in about 2 minutes.

Unlike top-entry mechanical mixers that move the liquid contents in a horizontal motion and sometimes create a vortex, the 5-55 portable drum mixer from Pulsair creates a large compressed bubble of air or industrial gas at the bottom of the drum allowing for vertical mixing to occur. The bottom-up mixing method allows the operator to mix the contents faster than traditional methods and also keeps liquid solids or slurries agitatated and suspended if required. Additionally, the powerful force of the compressed bubble generated at the bottom of the tank allows for heels to be broken up and quickly mixed back into the liquid contents.
