Why Graco Container Unloading Systems?

Inflatable Seal

Graco's inflatable wiper seal is available on our drum unloaders and our Bin Evacuation Systems. The seal inflates to conform to the container type and shape, which wipes down the sides of the container cleanly. The inflatable wiper seal also accommodates the unloaders to conical and tapered drums.

Food Safety

The SaniForce line was designed for hygienic and sanitary ingredient transfer, which is notable in several aspects of the pump and system construction. The SaniForce piston pumps are built with sanitary flanges, quick knock down connections and a FDA compliant shroud for the air motor, which makes cleaning, and sanitization a breeze. The drum unloader and bin evacuation systems are also designed to help protect the ingredients from external contamination and bacteria because the follower plate and inflatable seal come in contact with all sides of the bin or drum, keeping the product covered during transfer.

Evacuation Efficiency

Graco's drum unloaders and our Bin Evacuation Systems provide evacuation rates of up to 99%. This is a drastic improvement over other evacuation methods such as dumping or scooping, saving overall production time, reducing potential contamination and increasing worker safety. 

Worker Safety

Repetitious movements and repeated heavy lifting creates a risky environment for work related injuries and accidents. The SaniForce Elevators, Drum Unloaders and Bin Evacuation Systems replace traditional scooping methods to prevent potential employees from potential injury and companies from liability from such types of incidents caused by repeated actions and scooping.
