This inline liquid filling machine fills thinner, paint solvent, cleaning solvent, alcohol-based liquid and other compatible low-viscosity industrial liquids. The four-head gear pump meters product into bottles while the diving nozzles move downward during filling to control splashing and foam. The configured filling range covers 100 ml to 2 L. The reference platform targets flammable liquid products including alcohol, fuel, perfume, disinfectant and other chemical liquids, but actual product compatibility should match the pump, seals, hoses and electrical protection used on the ordered machine.
