Which filling machine is best for still water?
The best starting point is a gravity, pump, flow, level or volumetric route selected from dose range, accuracy, pack and required output. Confirm it by trial because still water is free-flowing and low viscosity, and the route must also suit PET or glass bottles, the fill range, cleaning regime and required good output.

What should I check first?
Record the machine state and the finished result before changing settings. This helps identify where control is first being lost.
- Confirm the production condition of still water: free-flowing and low viscosity.
- Measure the limiting pack details for PET or glass bottles, including opening, stability and fill range.
- Check that product reaches the machine through a clean constant-head tank or controlled pump supply.
- Record ten consecutive fills by weight and note the product temperature, density or batch condition.
- Confirm the product supply remains stable at minimum and maximum hopper or tank levels.
Why is this production problem happening?
Work from the evidence and change one variable at a time. These are the most relevant causes to investigate first.
- The selected method does not accommodate that still water is free-flowing and low viscosity.
- Product condition changes between the sample, start-up and a sustained run.
- Pack tolerance or presentation is influencing the measured result.
- The dosing principle is unsuitable for viscosity, particles, aeration or accuracy.
- Product conditions are changing during the run.
How can I correct or improve it?
Make a controlled change, repeat the same measurement and compare the result before moving to the next adjustment.
- Trial still water using representative production batches and the full pack matrix.
- Use a gravity, pump, flow, level or volumetric route selected from dose range, accuracy, pack and required output.
- Plan changeover around this requirement: drain, rinse and verify hygiene controls.
- Stabilise product temperature, mixing and supply before retuning.
- Test a representative product and pack matrix across the full fill range.
What should I send Lancing?
The most reliable recommendation is based on representative production materials and a measurable acceptance result.
- Representative sample of Still water
- All relevant PET or glass bottles
- Target fill and tolerance
- Required accepted output
- Photographs or video of the current process
- Product name and a sample or SDS where relevant
- Viscosity, temperature, particles, foaming and density

What should I check first for still water?+
Confirm the production condition of still water: free-flowing and low viscosity.
Why does this problem happen with still water?+
The selected method does not accommodate that still water is free-flowing and low viscosity.
How can I improve or correct the problem with still water?+
Trial still water using representative production batches and the full pack matrix.
Which part of the production line does this question relate to?+
This question relates primarily to filling & dosing. It may also be affected by upstream product or pack supply and by downstream handling, so check the full production sequence rather than one machine in isolation.
What should I send when asking for a machinery recommendation?+
Send Representative sample of Still water; All relevant PET or glass bottles; Target fill and tolerance; Required accepted output. Representative production samples and a measurable acceptance target are normally more useful than a catalogue description alone.
