Chemical Liquid Filling Machine

Our chemical liquid filling machines handle a broad range of industrial liquids: acids (hydrochloric acid up to 30%, sulfuric acid up to 30%, phosphoric acid, acetic acid), alkalis (caustic soda solution, ammonia solution, potassium hydroxide), organic solvents (acetone, ethanol, isopropanol, toluene, xylene), specialty chemical intermediates, cleaning agents and disinfectants, agricultural chemicals and pesticide formulations, and industrial coatings and adhesives. Wetted part material selection (SUS316L, HDPE, PTFE, Hastelloy) depends on the specific chemical product. We require a complete chemical specification sheet including concentration, temperature, density and viscosity to confirm material compatibility.

Net-weight filling measures the actual mass of liquid dispensed into each container, independent of container tare weight variation or liquid density changes. The container sits on a load cell platform. The system records container tare weight, opens the fill valve (fast-fill to ~90% of target weight), then switches to slow top-off mode approaching the target, and closes the valve at exact target net weight. Accuracy of ±0.2% is achieved across the 1L–1,000L range. This method handles density variations between product batches without recalibration — important for chemical liquids where concentration variations affect density.

Chemical liquid filling machines differ from standard filling machines in: (1) wetted part materials — chemical-grade SUS316L, PTFE, HDPE instead of standard stainless steel; (2) corrosion protection on all surfaces exposed to chemical vapors; (3) ATEX-rated electrical systems for flammable chemicals; (4) closed-loop filling connections to prevent vapor release (particularly for volatile organics and concentrated acids); (5) secondary containment and drip trays for corrosive products; (6) emergency stop and automatic valve-close systems; (7) anti-syphon valves to prevent post-fill drip of aggressive chemicals.

We offer three primary configurations: (1) Bottle filler (1L–20L): Piston or peristaltic pump filling with bottom-up nozzle, conveyor-fed, suitable for acid bottles, solvent canisters and industrial chemical bottles — 500–2,000 bottles/hr. (2) Drum filler (50–200L): Net-weight load cell control, 60–120 drums/hr, ATEX Zone 1/2 options. (3) IBC/tote filler (500–1,000L): High-flow fill head with closed-loop connection, 15–30 IBCs/hr. All configurations available with ATEX certification, SUS316L or HDPE wetted parts, and integration into existing production lines.
