Define product behaviour
Record viscosity, foam, corrosiveness, flammability, solids, temperature and cleaning needs.
Buyer guide
Choosing a chemical filler is easier when the decision is broken into product behaviour, filling principle, container, closure, output and installation. Use this guide to prepare a stronger brief before requesting a quote.
Process
Record viscosity, foam, corrosiveness, flammability, solids, temperature and cleaning needs.
List known compatible or incompatible contact materials, seals and tubing.
Compare pump, piston, peristaltic, gravity, flow meter or weight filling.
Measure bottles, necks, jerrycans, pails, tins or drums.
Choose capper style from screw cap, trigger, pump, ROPP, plug, bung or lid.
Use containers per minute or per hour, but include changeovers and operator tasks.
Consider labelling, coding, conveyors, guarding, utilities and installation before purchase.
Comparison
| Principle | Often considered for | Watch points |
|---|---|---|
| Pump filling | Free-flowing liquids, oils, detergents | Pump compatibility and product shear |
| Piston / volumetric | Controlled doses, viscous products | Cylinder size, cleaning and product contact |
| Peristaltic | Small batches, clean tube contact, selected specialist liquids | Tubing compatibility and flow rate |
| Diaphragm / gear pump | Foamy products, gels, oils and selected chemicals | Compatibility, accuracy and viscosity range |
| Weight filling | Jerrycans, pails, drums and larger fills | Scale accuracy, speed and handling |
| ATEX option | Flammable liquids and solvents | Site zoning and formal assessment requirements |
Specification
Two products can both be described as chemicals but require very different machinery. A thin solvent, foamy cleaner, acidic descaler and adhesive can each call for a different design even when the fill size is similar.
Note
When comparing quotes, check what is included: filling machine, capping, conveyors, labelling, change parts, commissioning, training, spares, delivery and installation assumptions. A cheaper headline machine can cost more if key line items are missing.
FAQ
Start with the product behaviour and compatibility. That affects the pump, nozzle, valves, seals, tubing, frame environment and sometimes the complete line layout.
Semi-automatic is useful for flexibility, short runs and lower output. Automatic is better where repeated production, lower labour input and line integration justify the investment.
Sometimes, but the practical compromise may be high. Container handling, fill volume range and nozzle position should be reviewed before assuming one machine can do both well.
Compare scope, assumptions, materials, support, change parts, capping and labelling integration, installation, training and aftercare rather than only the machine price.
