Good specification practice
Do not choose a machine only by fill speed. Check uptime, cleaning time and repeatable setup.
Maintenance guide
Filling machine maintenance should be planned before the machine is specified.
The right filling machine route should account for cleaning access, seal wear, nozzle care, product contact parts and operator skill level.

Maintenance checks
These are the main points to check before asking for a quote. They help avoid a filler that looks suitable on a catalogue page but fails in real production.
- How often product changeover and cleaning will happen.
- Which seals, nozzles or product-contact parts may need routine inspection.
- Operator access to hopper, pump, piston and filling nozzles.
- Availability of utilities, spare parts and maintenance routines.

FAQs
Common questions.
Maintenance varies by machine type, but routine checks often include seals, tubing, nozzles, product contact parts, sensors and moving components.
Yes. Abrasive, sticky, corrosive or particulate products can change inspection and cleaning needs.
Yes. Cleaning time can have a major impact on real production output.
Yes. Operators need safe access for cleaning, adjustment and routine checks.

Condition-based checks
Link maintenance observations to fill results and product-path condition.
Lancing VF documentation identifies piston-head O-rings and nozzle seals as service items that can be exposed, inspected and replaced. The actual maintenance plan must follow the supplied machine manual, duty, product compatibility and site risk assessment rather than an invented universal interval.
| Area | Condition to observe | Possible production symptom |
|---|---|---|
| Piston seals and cylinder | Wear, scoring, swelling, lubrication condition and leakage. | Inconsistent suction, quantity drift, product bypass or slow movement. |
| Valve and seats | Trapped product, wear, free movement and seal condition. | Poor refill, drip, incomplete discharge or particle damage. |
| Nozzle and seals | Closure, retained product, wear and alignment. | Tailing, drip, splash, air draw-back or pack contamination. |
| Air system | Leaks, regulator recovery, water, hoses and fittings. | Slow or incomplete cylinder, gate or nozzle movement. |
| Sensors and conveyor | Alignment, contamination, loose mounts, guides and transfer points. | Missed containers, incorrect gating, spills or line stops. |
Maintenance and safe intervention must be managed under the site's risk assessment, isolation procedures and applicable work-equipment duties. The HSE provides current PUWER information covering inspection, maintenance, training and competence.
Keep controlled spare and change parts using the change-parts guide.
Maintenance records
Record the intervention and the production checks as one event.
Which records are useful when output changes after filler maintenance?
Keep the replaced part identity, assembly arrangement, date, reason for the work and first accepted fill results together. Note any simultaneous recipe or product change. This lets an engineer distinguish the maintenance intervention from a new operating condition, instead of attributing all later variation to the replacement part.
For tube-based filling, consult tube selection and verification. For cleaned or dismantled piston paths, use the cleaning-route assessment and retain the approved reassembly instructions. Do not open moving or pressurised equipment to investigate a dose problem; follow the manufacturer’s isolation procedure and HSE maintenance guidance.
Send the machine identity, intervention record and results to Lancing when requesting a technical review. A photograph of a removed part should not replace its material or part-code documentation.
