Selection and comparison guides
Choosing a filler is easier when you work backwards from the product, container, output and accuracy requirement. This page explains the main specification decisions before you compare machines.

Buyer intent guide
The best choice is rarely decided by one factor. A method that works well for a thin chemical may not suit a viscous food product, and a machine that is fast on one bottle format may slow down when changeovers are frequent.
Viscosity, foam, particles, temperature and chemical compatibility.
Bottle, jar, pail or jerrycan size, neck opening, stability and closure.
Fill volume or weight, accuracy tolerance and required bottles or packs per minute.
Manual loading, semi-automatic operation, compact automation or full inline production.
Specification notes
These points help make an enquiry more accurate and reduce the risk of selecting the wrong filling principle.
The same bottle filling machine can perform very differently when the liquid changes. A water-thin cleaner, a foaming detergent, a viscous sauce, a fragrance oil and a corrosive chemical each create different challenges. Product behaviour drives pump selection, nozzle design, materials and speed.
For a strong recommendation, include the product type, approximate viscosity, whether it foams or strings, whether it contains particles and whether it needs heating, mixing or special materials.
Filling speed should be balanced with capping, labelling, operator loading and packing. A fast filler does not improve the line if bottles cannot be presented, capped or labelled at the same rate.
For growing production, Lancing can discuss a sensible route from semi-automatic equipment to compact automation or a fully automatic filling line.

Send the product name, viscosity or sample details, fill volume, container dimensions, closure type, required output, cleaning needs and any safety or material compatibility requirements.
Yes. Lancing can discuss semi-automatic, compact and fully automatic configurations depending on output target, product behaviour, budget and future production plans.
The correct method depends on viscosity, foaming, particles, fill range, container type, accuracy requirement and production speed. A short specification review is usually the safest way to narrow the options.

A gated selection process
A useful selection process moves through a series of engineering gates. At each gate, either the available evidence supports the proposed method or an action is raised for a sample, drawing, safety review or trial. This is more reliable than comparing brochures in which each supplier has used different products, containers and test conditions.
Begin with the controlling constraints: hazardous-area obligations, product-contact compatibility, particle passage, cleaning and the minimum or maximum dose. Then compare practical production formats and output. Features such as recipes, extra heads or automatic container transport should only be considered after the basic product path is proven.
Review the SDS where relevant, site classification, product-contact materials, cleaning agents, temperature and pressure. Reject any route that cannot be supported with verified compatibility or the required project documentation.
Check viscosity range, foam, particles, shear sensitivity, air, suction conditions and dose. Compare the complete path from source to nozzle, not just the nominal pump description.
Check container opening, stability, closure, batch size, changeover, good output and operator work. Decide whether manual presentation, a compact cell or full automation is justified.
Specification and trial evidence
Score only with evidence. Mark unknown items as trials or project actions instead of assigning an optimistic value.
| Selection point | What to define or test | Why it matters |
|---|---|---|
| Product compatibility | Materials, seals, tube or valve path, temperature and cleaning | Pass / action / reject |
| Metering suitability | Dose range, viscosity, particles, foam, air and required measure | Pass / trial / reject |
| Nozzle and pack | Opening, fill height, splash, drip, neck access and stability | Pass / sample trial / change required |
| Output | Good packs after refill, checks, capping and routine stops | Meets shift target / further study |
| Changeover | Product drainage, cleaning, parts, calibration and first approved pack | Acceptable / improvement required |
| Integration | Supply, conveyor, capper, labeller, coder, inspection and controls | Defined / open interfaces |
| Support evidence | Manuals, drawings, trial report, acceptance record and training needs | Included / clarify scope |
Buyer questions
Ask what the product does at the real filling temperature and how it must be cleaned. That determines which metering paths deserve further comparison.
Size it for the required good output with realistic product supply, container handling and downstream operations. Excess speed can add cost and complexity without improving finished production.
Include all intended products, then identify the edge cases that control the design. If those products require incompatible contact materials or very different metering principles, more than one configuration may be sensible.
Give each supplier the same product, pack, output and acceptance brief. Ask them to state assumptions and test conditions for any quoted accuracy or speed.
It is particularly valuable where viscosity, foam, particles, small doses, stringing, unusual packs or aggressive liquids make desk-based selection uncertain.
Freeze the agreed product and pack range, interfaces, acceptance criteria, documentation and responsibilities so later changes can be assessed rather than absorbed informally.
