Product behaviour
Confirm viscosity, foaming, corrosiveness, flammability, solids, fumes and cleaning requirements before choosing pump and nozzle type.
technical term
Wetted parts are the machine components that contact the product during filling.
Specification guide
In a chemical filler, wetted parts can include the product tank, hoses, pump, seals, valves, nozzles and any fittings that touch the liquid. These materials need to be compatible with the product.
For corrosive liquids, the wrong material can fail, contaminate product or create maintenance problems. For solvents, seals and hoses may be as important as metal parts.

Always send an SDS and product details before assuming a material is suitable.
Buyer checks
These points are included because they match the practical questions buyers usually ask before requesting a chemical filling machine quotation.
Confirm viscosity, foaming, corrosiveness, flammability, solids, fumes and cleaning requirements before choosing pump and nozzle type.
Bottle, jerrycan, pail or drum shape affects handling, neck access, fill height, cap torque, label position and conveyor layout.
Hourly target, batch size, changeover and operator availability decide whether semi-automatic, compact automatic or inline filling is most practical.
Wetted materials, hoses, seals, pumps and nozzles should be reviewed against SDS data and the actual product sample.
Capping, labelling, coding, checkweighing, accumulation and pack-off should be considered early to avoid bottlenecks.
Air, power, space, ATEX zoning, ventilation, drainage, manual handling and cleaning access affect the final layout.
Planning table
| Detail | Why it matters |
|---|---|
| Product name and SDS | Shows chemical compatibility, flammability, corrosiveness and handling considerations. |
| Fill volume range | Controls dosing system, cylinder size, pump choice and changeover approach. |
| Container drawings or samples | Confirms neck size, stability, cap style, label position and conveyor handling. |
| Closure type | Determines screw capping, trigger fitting, pump closure handling, torque control or cap feeding. |
| Output target | Separates manual, semi-automatic, compact automatic and multi-head line routes. |
| Site notes | Power, air, space, operator access, ventilation and zoning can change the recommended line. |
Common questions
No. The product data, pack size, site conditions and output target decide whether this method or component is suitable.
Send the SDS, fill range, container and closure samples, accuracy needs and production target.
Yes. Filling, capping, labelling and conveyors can be reviewed together.
