This automatic filling machine for liquid fills blue medicinal solution, detergent, washing liquid, alcohol, engine oil, shampoo, fruit juice, cooking oil, liquid chemicals, and other free-flowing or moderately viscous products. The self-priming pump transfers liquid to the filling section, while three gravity filling heads dose large containers by weight. This setup targets 10L, 20L, 30L and other large-volume packs where weight control matters more than high bottle speed.
