This chemical filling machine fills disinfectant liquid, cleaning solution, bleach-based cleaner, sanitizer, detergent liquid, and other low-viscosity chemical products into bottles. A 2000 L corrosion-resistant plastic mixing tank stores and mixes the liquid before the self-priming pump transfers it to the filling section. The chemical liquid filling machine then completes filling, capping, coding, labeling, bundle wrapping, and heat shrinking at up to 50 bottles/min, depending on bottle size and filling volume.
