Maintenance effort should follow the wear map, not the machine layout. Seals, capping inserts, guide rail blocks and filters account for most unplanned stops; painting and polishing account for none. A short daily check on those four items beats a long monthly inspection.
Raw water, neck finish and the filler-capper match decide more about a water line than its BPH. Most of the meeting goes on BPH; the other two get a fraction of the time. Rinser clamps and capping heads are cut for one neck finish; a 1 mm thread change means new change parts rather than a new machine.
| Filling principle | Best for | Watch out for |
|---|---|---|
| Gravity | Still water, one rigid bottle size | Thin-wall bottles deform under head pressure |
| Volumetric valve | 3-15 L and mixed formats | Valve wear shows as slow drift, not a sudden error |
| Isobaric | Carbonated water only | Needs counter-pressure, so slower per valve |
| Load cell | Oil and high-value liquid | Slower cycle, higher cost per valve |
For the same duty in another bottle format, the Blow-fill-cap Combibloc for Still Water is specified separately.
Gravity filling holds a level in a rigid bottle and costs least per valve. Volumetric filling doses a fixed volume into a chamber, so it holds accuracy across 3 L, 5 L and 10 L formats without changing the head. Isobaric filling is for carbonated product only, because it keeps CO2 in solution under counter-pressure. A still water line never needs it.
Sizing for this duty runs through the Gravity Filling Machine for Still Water, where the valve count is set out.
A small line gives up automation, not quality. Manual or semi-automatic packing, fewer accumulation buffers, and a simpler CIP usually follow. What it should not give up is the filling valve and the capping head, because those two decide whether the product is saleable.
The same question is worked through from another angle in Steps to Set Up a Complete Water Filling Line.
Gravity holds a fill level, so accuracy depends on bottle geometry. A volumetric filler measures a chamber volume, which keeps it accurate when the format changes. For one rigid bottle size, gravity is enough; for 3-10 L or mixed formats, volumetric is safer.
Plan for 380 V three-phase power, 0.6-0.8 MPa compressed air, and a chiller if blow molding runs in-house. Exact consumption belongs in the utility schedule of the quotation, not in a rule of thumb.
For a complete line with blowing, filling, labelling and packing, plan several weeks on site after arrival, plus operator training. Civil work and utility readiness are the usual delay, not the machinery.
Not on the same filler. Carbonation needs isobaric valves, a CO2 dosing and mixing unit, and a different bowl. A combiblock can carry both valve sets, but they are separate specifications, not a field conversion.
