Our pail filling machines handle round metal and plastic pails from 1L to 25L. Common sizes include 1L, 2.5L, 4L, 5L, 10L, 15L, 20L and 25L pails — the full range used in paint and coating production. The conveyor lane guides and fill head height adjust to accommodate different pail heights and diameters. For a mixed production line running multiple pail sizes, a single machine with PLC-stored recipes handles the full range with format changeover under 10 minutes.

For standard 5L paint pails, our pail filling machine achieves 400–600 pails/hour on a single-head machine. Speed depends on product viscosity and required settle time on the load cell. Low-viscosity water-based paints achieve higher speeds (up to 800/hr for 5L), while high-viscosity alkyds or thixotropic paints fill at 300–400/hr for 5L. High-speed dual-head configurations can double throughput to 800–1,200 pails/hour.

Yes. For solvent-based paints with flash points above 60°C, our standard CE-certified pail filling machine is suitable. For flammable solvent-based paints with flash point below 60°C, we offer ATEX Zone 2 rated pail fillers. All wetted parts (fill nozzle, pump, seals) in SUS316L with PTFE gaskets for compatibility with solvent-based coatings, alkyd resins and epoxy paints.

Semi-automatic pail filling machines (operator places empty pail, machine fills and stops) start from approximately $12,000–$25,000. Fully automatic pail filling lines (conveyor-fed, automatic lid seaming, labeling) range from $40,000–$120,000 depending on speed and integrated functions. ATEX-rated versions carry a 30–50% premium over standard versions. Contact us with your pail size, product type, required throughput and site classification for an accurate quotation.
