Chemical filling machinery
Protect product-contact parts when filling bleach, acids, cleaners and aggressive liquids, with ATEX features included where your product or site requires them.
Two separate questions
Aggressive chemicals can attack stainless steel, seals, hoses and valves. Flammable products can create a potentially explosive atmosphere. Some projects involve one issue; others involve both.
The exact concentration, temperature, contaminants, cleaning chemicals and dwell time determine the compatible product-contact materials.

FAQs
No. Bleach is primarily a corrosive-product and material-compatibility challenge. Whether explosion protection is required depends on the full product composition and workplace assessment.
Depending on compatibility, product-contact routes may use PP, PTFE, PVC or selected alloys and elastomers. Compatibility must be confirmed against the exact chemical concentration, temperature and cleaning method.
Potentially, but that creates a combined specification. Corrosion resistance does not by itself address ignition risks, zone requirements or conformity documentation.

Materials evidence
“Corrosion resistant” is not a single construction standard. Compatibility depends on the exact substance, concentration, contaminants, operating temperature, exposure time, pressure, cleaning medium and mechanical duty. The evidence should cover every wetted component and the foreseeable cleaning state.
| Wetted-path area | Evidence to confirm | Why it matters |
|---|---|---|
| Tank, manifold and valves | Candidate material, concentration and temperature limits, joining method and any coating or lining. | Bulk construction may be suitable while welds, fittings or linings remain vulnerable. |
| Seals and elastomers | Exact seal compound, swelling or embrittlement data, service life and replacement method. | A compatible body material does not protect an unsuitable seal. |
| Hoses and tubing | Inner liner, reinforcement, end fittings, bend radius, permeation and static behaviour. | Flexible connections can introduce chemical, mechanical and electrostatic constraints. |
| Pump and meter | Wetted materials, operating principle, viscosity range, dry-running limits and cleanability. | The dosing device often contains several different materials and clearances. |
| Nozzles and drip control | Body, valve seat, seals, cut-off, retained volume and dismantling or flush method. | Nozzle residues affect drips, cross-contamination and operator exposure. |
| Cleaning state | Flush medium, temperature, contact time, disposal and evidence of a clean or neutral condition. | The cleaning chemical can be less compatible or more flammable than the product. |
The source data and supplier approval should relate to the actual formulation and operating conditions. Unknown cells in a compatibility review should remain open actions rather than being filled with assumptions.
Combined specification
A machine may need only corrosion-resistant contact parts, only hazardous-area protection, or both. The product SDS and formulation support both reviews, but the conclusions are different. The material review addresses degradation, contamination, leakage and cleaning; the ATEX/DSEAR review addresses explosive atmospheres, ignition sources, release control and the site classification.
Where practical, run the real product through representative wetted components and observe fill behaviour, staining, swelling, leakage, valve response and cleaning. Longer-term compatibility may require supplier data or controlled exposure evidence beyond a short filling trial.
Agree inspection points and consumable replacement intervals. Seals, hoses and valve seats should be identifiable in the spare-parts list so that a future substitution does not silently change the approved material route.
Define drainage, drip trays, bund or local containment interfaces, transfer connections and the route for waste or recovered product. Cleaning access should avoid creating an uncontrolled splash, vapour or incompatible mixture.
If the product or cleaning medium can create an explosive atmosphere, the cleaning mode belongs in the hazardous-area and operating assessment. A machine that is safe during production cannot automatically be assumed safe during open flushing or maintenance.
No material should be treated as universally suitable. Confirm the exact grade, product formulation, concentration, temperature, pressure, exposure and mechanical duty using reliable supplier or test evidence.
Suitability depends on the exact chemistry and conditions. Chlorides, oxidisers, concentration and temperature can change corrosion behaviour, so the wetted-path material should be approved for the declared product rather than selected from a broad product category.
Provide the current SDS, full formulation or concentration where available, operating and cleaning temperatures, exposure time, pressure, viscosity, proposed cleaning media and any existing compatibility or service-history evidence.
General chemical-filling selection where no hazardous-area intent exists is owned by chemicalfillers.co.uk. This page remains focused on the point where materials compatibility and ATEX requirements may need to be specified together.
Materials evidence
Frame material alone does not establish compatibility. The review should identify hoses, seals, valve seats, pumps or pistons, meters, nozzles, tanks, fasteners and temporary cleaning connections that contact product or cleaning media.
List each product, concentration, temperature, exposure time and cleaning medium against the actual component or supplier part. Record evidence, limitations and any component that is changed between campaigns.
A chemically resistant path does not itself control electrical or mechanical ignition risks. Where flammable atmospheres are possible, complete the hazardous-area and equipment assessment in parallel.
Use the cleaning and changeover guide and maintenance guide to retain the approved condition through production.
Compatibility evidence
A corrosion-resistant filler can use several materials across pumps, hoses, valves, seals, manifolds and nozzles. The correct combination depends on exact chemistry, temperature, movement, exposure time and cleaning; a broad product name or pH value cannot approve the assembled path.
Every component that contacts the product, cleaning fluid or retained residue needs an evidence basis. Include the source vessel interface, feed pump, hose lining, fittings, diaphragms, valve seats, dynamic seals, metering chamber, manifold, nozzle internals, drain and recovery path.
A trial can show immediate process behaviour and obvious reactions, but it does not normally prove long-term corrosion, permeation, ageing or seal life. Use the trial for fill, drip, foam, drainage and cleaning observations while retaining supplier material evidence and user approval for service life.
| Change | Why the previous approval may no longer apply | Evidence to refresh |
|---|---|---|
| Formulation or concentration | Additives, oxidising strength, solvent content or water content can alter material response. | Current SDS, formulation data and component-supplier recommendation. |
| Product or cleaning temperature | Higher temperature can accelerate attack, swelling, permeation or loss of mechanical properties. | Temperature-specific compatibility and revised trial/cleaning conditions. |
| Seal, hose or valve replacement | Parts with the same dimensions can use different compounds or reinforcement. | Controlled part specification and verification against the approved schedule. |
| Longer retention or soak cleaning | Extended contact can produce effects not visible in a short production run. | Exposure-time basis and inspection/replacement plan. |
Use the SDS information guide to collect the hazard starting point, then add the exact process and cleaning data needed for a component-level compatibility decision.
