| Where it fits | Still water, RO water, mineral water |
| Filling system | Gravity or volumetric valve |
| Output 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 |
A water line stands or falls on three inputs: raw water analysis, neck finish, and how well filler and capper are matched. BPH takes the meeting; the neck finish and the capper match get the last five minutes. 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.
Water per bottle, energy per bottle, carbon (Scope 1/2/3), waste and packaging recyclability.
Star wheels, guide rails, grippers, cap chute and filling recipe all change with the format. The parts are not the cost; the time is. Two formats on one line typically cost 40-90 minutes per switch, which is why the production factor falls from about 0.85 to 0.70 and why a second small line is sometimes cheaper than one flexible line.
| 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 Gravity Filling Machine for Still Water is the matching unit when this becomes a line project.
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.
The specification sheet for the Volumetric Filling Machine for Still Water carries the utility figures quoted here.
Temperature, valve wear and bottle variation, in that order. Water is less sensitive than oil, but a warm product foams more and a worn valve closes late. Weighing a sample every few hours catches the drift before it reaches the customer.
The same question is worked through from another angle in 2000BPH 5-Gallon Filling Line Ready for Shipment.
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.
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.
Commercial practice is a stated band per bottle size, typically checked by weight at the filler outlet. The band belongs in the acceptance protocol. A line without a written tolerance will argue about it at commissioning.
