This liquid bottle filling machine handles disinfectant, hand sanitizer, alcohol solution, mouthwash, glass cleaner, liquid detergent, body wash, shampoo, juice, edible oil, sauce, and other flowing or moderately viscous liquids. Four piston filling heads meter several bottles during each cycle. The suck-back system pulls residual liquid away from the nozzle tip after filling, which helps control dripping around the bottle mouth.
