| Where it fits | Still water, RO water, mineral water |
| Filling method | Gravity or volumetric valve |
| Capacity range | 5,000-48,000 BPH at 500 ml |
| Bottle range | 200 ml to 16 L, by configuration |
| Wetted parts | SUS 304 product contact, CIP-ready |
| Line scope | Treatment, blowing, filling, capping, labelling, packing |
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.
A water line stands or falls on three inputs: raw water analysis, neck finish, and how well filler and capper are matched. 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 |
The specification sheet for the Blow-fill-cap Combibloc for Still Water carries the utility figures quoted here.
Mineral water is defined by its source and its mineral profile, so treatment is limited to what the label claim allows. Purified water starts from any feed and is built up to a specification. The filling machine is the same; the treatment train and the legal claim are not.
Rated output, change parts and services are listed on the Gravity Filling Machine for Still Water page.
A water line is cleaned on a fixed cycle plus a changeover clean. The circuit covers the filler bowl, the product pipes and the filling valves. Ozone or heat is used for disinfection, and the cycle time is a planned stop rather than an incident.
The same question is worked through from another angle in The Complete Guide to Automatic Bottled Water Production Lines.
A lighter bottle is less rigid, so it deforms more under the filling head and grips differently in the star wheels. The filler may need a different neck handling and a lower contact pressure. Lightweighting is a bottle project that reaches into the filling line.
200 bottles per minute. Divide BPH by 60. A 24,000 BPH line runs at 400 bottles per minute, which is why filler and packer have to be matched rather than bought separately.
Gravity holds a fill level, so accuracy depends on bottle geometry. Because volumetric filling doses by chamber volume, accuracy holds across bottle sizes. For one rigid bottle size, gravity is enough; for 3-10 L or mixed formats, volumetric is safer.
It depends on whether blowing, packing and palletizing sit in the same hall. Fix the footprint by drawing the layout at 1:100 with conveyor radii included, then check the turning radius of the largest format.
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.
