Filling machine spare parts: what to keep in stock and when to order
The right spare parts strategy prevents unplanned downtime without tying up capital in inventory. Here is what to keep and what to leave on the supplier's shelf.
The right spare parts strategy prevents unplanned downtime without tying up capital in inventory. Here is what to keep and what to leave on the supplier's shelf.
Maintenance is the largest variable in filling machine total cost of ownership. A structured programme prevents unplanned downtime and extends service life.
What to consider
- Daily checks — leaks, lubrication, sensors — prevent most unplanned stops.
- Seals, gaskets and O-rings are the highest-wear items and should be stocked.
- Annual overhauls restore accuracy at a fraction of replacement cost.
- Records turn maintenance from memory into evidence for audits.
Common pitfalls
- Skipping daily checks and paying for it in unplanned stops.
- Using aftermarket seals that drift or fail early.
Questions to ask your supplier
- What does the maintenance manual schedule look like?
- Are spare parts available for the machine's expected service life?
Which spare parts matter most for filling machines — seals, valves, pump heads, sensors and nozzles — and how to build a spare parts strategy that prevents unplanned downtime.
