Product behaviour
Check viscosity, foam, particles, settling, temperature, abrasiveness, corrosiveness and cleaning requirements.
Buyer guide
How to choose a volumetric filling machine.
A practical checklist for deciding whether piston, pump or cup filling is the correct route before you request a quotation.
Decision framework
Five checks before selecting a machine.
Fill range
Confirm minimum and maximum dose, container opening, nozzle count and whether volume adjustment needs recipe control.
Accuracy route
Decide whether volumetric repeatability is enough or if net-weigh verification is needed for trade-weight products.
Output target
Compare bottles per minute against operator loading, capping speed, labelling speed and downstream packing.
Cleaning & changeover
Review contact parts, product swaps, allergen risk, washdown, CIP expectations and tool-less changeover needs.
Integration
Plan bottle infeed, conveyors, capping, labelling, coding, inspection, guarding, accumulation and discharge.
Specification notes
What to put in your enquiry.
A strong brief lets Lancing UK compare the machine route faster and avoid over-specifying or under-specifying the filler.
- Product name, viscosity, temperature, particles and cleaning needs.
- Container type, size range, neck/opening and closure type.
- Fill volume range and target accuracy expectation.
- Target output, current bottleneck and available floor space.
- Existing machinery to connect with or future line stages to allow for.
Technology comparison
Common filling principles.
| Principle | Where it works well | Watch-outs | Typical automation level |
|---|---|---|---|
| Piston volumetric | Viscous liquids, sauces, creams, gels and repeatable doses | Product particles, cleaning and cylinder/nozzle sizing | Semi automatic to fully automatic |
| Volumetric cup | Free-flowing granules and consistent bulk-density products | Bulk-density variation and product flow stability | Automatic or integrated with bagging/bottle filling |
| Peristaltic pump | Clean liquid path and easier tubing changeover | Flow rate and tubing compatibility | Bench, semi automatic or compact line |
| Gear/rotor pump | Flowing liquids and viscous products where pump control is preferred | Product compatibility and cleaning route | Semi automatic to automatic |
FAQs
Buyer questions.
No. Start with product behaviour, fill accuracy, output and changeover needs. A cheaper machine that cannot handle the product or pack format can cost more once production issues are included.
Accuracy depends on product, dosing principle, fill volume and setup. Piston systems can provide strong repeatability when the product is suitable and the machine is configured correctly.
Move to automatic when labour cost, output target, consistency, queueing at capping or labelling, or finished-pack presentation requires continuous line control.
