Liquid behaviour
Confirm whether the product is thin, viscous, foamy, abrasive, fuming, corrosive or solvent-based. That guides pump selection, nozzle design, wetted materials and cleaning access.

Plastic contact vs stainless steel chemical fillers
This page helps UK manufacturers planning corrosive liquids, detergents, solvents and oils to compare filling machinery around choosing contact materials around compatibility and clean-down.
- Built around product behaviour, fill volume and container format
- Includes filling, capping, labelling and conveyor considerations
- Useful for early budget, upgrade and specification discussions
Buyer guidance
What to check before choosing equipment
Plastic contact vs stainless steel chemical fillers should be specified from real production details, not from a generic machine list. The product, packaging and site conditions all affect the safest and most practical route.
Container and closure
Send bottle, jerrycan, pail or drum samples with caps, triggers, pumps, labels and neck details. Container stability and cap style often decide how the line should be laid out.
Throughput target
Define packs per minute, packs per hour or packs per shift. The target output determines whether a compact, semi-automatic, multi-head or fully integrated route is suitable.
Recommended route
Plastic-contact and stainless wetted-part comparison
For corrosive liquids, detergents, solvents and oils, the correct machinery route depends on how the liquid behaves during filling and how the pack behaves during handling. A simple filler may be right for low-volume production, while higher output normally requires conveyors, container control, cap handling and labelling to be specified together.
Where products are corrosive, flammable, fuming or difficult to clean, the discussion should include SDS data, site constraints, wetted parts, hoses, seals, guarding and operator workflow before equipment is finalised.
Machine choice
Typical options to compare
The table below is a practical starting point for narrowing the specification.
| Option | Useful when | Points to confirm |
|---|---|---|
| Compact or benchtop filling | Small batches, samples, start-up production or limited floor space. | Operator handling, product feed, cleaning and future upgrade path. |
| Semi-automatic filling | Manual filling is too slow or inconsistent, but a full line is not yet required. | Nozzle control, container holding, fill accuracy, drips and changeover. |
| Automatic filling line | Repeat production needs higher output and consistent pack presentation. | Conveyors, cap handling, labelling, coding, guarding and line speed. |
| Specialist or ATEX discussion | The product is flammable, corrosive, fuming, hazardous or site-sensitive. | SDS, zoning, compatibility, operator exposure and installation environment. |
Common questions
Questions buyers ask
Can this be quoted without samples?
An initial discussion can start from photos and data, but final machinery selection is stronger when product, container and closure samples are available.
Should capping and labelling be included from the start?
Yes, especially when target output matters. A filler that is faster than the capper, labeller or operator process will not improve the full line.
What if one line must fill several products?
Changeover, clean-down and compatibility need to be reviewed. Some product ranges suit one flexible machine; others require different contact parts or separate routes.
Can corrosive or solvent products be discussed?
Yes. Send the SDS and describe the site. Corrosive, fuming, solvent or hazardous products need compatibility and safety considerations before quoting.
