Semi-Auto Industrial Drum Filling
Semi-automatic drum filling machine for 50L–200L drums. Manual drum placement, automatic fill and cut-off valve. Net-weight tolerance, throughput and ATEX documentation scope are reviewed by RFQ.
High-resolution load cell platform measures drum weight during the entire fill cycle. Fast-fill to a reviewed portion of target weight, then slow top-off to target target. Achieves tolerance by RFQ (by RFQ on a 200kg fill) — significantly better than volumetric systems. Automatic tare compensation handles drum weight variation without pre-weighing. Operator places the drum and presses start; the machine does the rest.
Semi-automatic drum filling machines offer net-weight accuracy equivalent to fully automatic systems at lower capital cost depending on scope. The operator provides drum loading/unloading labor while the machine delivers controlled, consistent fills. Ideal for paint and chemical manufacturers with throughput requirements of 200–500 drums/day that do not justify the investment in a fully automatic conveyor drum line.
Compatible with 50L, 100L and 200L steel drums (closed-head and open-head), UN documentation review chemical drums, and plastic IBC-style drums. Single fill head with adjustable height handles the full drum range. ATEX documentation review option for facilities filling flammable paint solvents, coatings or chemical products with flash points below 60°C. Anti-drip valve prevents drum exterior contamination.
A semi-automatic drum filling machine combines manual drum handling with automatic net-weight filling. The operator rolls or places the empty drum onto the weigh platform (using a drum roller or hand pallet truck), then initiates the fill cycle by pressing a foot pedal or control button. The machine opens the fill valve, monitors drum weight via load cells updated 200 times/second, slows the fill rate as it approaches target weight, and cuts off the valve at exactly the target weight. Accuracy of by RFQ (by RFQ on a 200kg fill) is standard. The operator then removes the filled drum and brings the next empty drum to the station.
A semi-automatic drum filling machine handles 30–60 drums/hour depending on product viscosity, drum size and operator efficiency. For standard paints and liquids with settle time of 3–5 seconds on the load cell, 45 drums/hour (approximately 80 seconds per drum cycle including operator handling) is a realistic production rate. High-viscosity products or drums requiring longer settle times reduce throughput. For comparison, a fully automatic drum filling line achieves 60–120 drums/hour with less operator involvement.
Semi-automatic drum filling machines require an operator to move each drum onto the weigh platform and remove it after filling. Fully automatic drum filling machines use roller conveyors to automatically index drums through the filling station, cap station and out to palletizing without manual handling between stations. Semi-automatic machines are usually quoted with a smaller equipment scope; fully automatic drum lines are quoted with conveyor, capping and handling integration. Semi-automatic is preferred when throughput is 200–500 drums/day, floor space is limited, or product mix requires frequent drum format changes.
Yes. ATEX documentation review (occasional explosive atmosphere) and Zone 1 (continuous explosive atmosphere) versions are available for our semi-automatic drum filling machines. Required when filling flammable products with flash point below 60°C, including most organic solvents, flammable paint thinners, petroleum products and reactive chemical intermediates. ATEX versions include explosion-proof motor, intrinsically safe weight indicator, anti-static fill head, bonding and grounding connections. Contact us with your product flash point and site area classification for the correct ATEX specification.
