Liquid fillingWhat information is needed to specify a filler for liquid suspensions?
Practical guidance for liquid suspensions: capture samples, dimensions, output, acceptance tests and site constraints before buying.
Read the answer →What normally controls the result?
The result depends on product behaviour, supply conditions, dosing principle, nozzle design and container control.
- Product temperature and viscosity
- Product supply pressure or level
- Dosing chamber, pump or valve condition
- Nozzle position and shut-off
- Container location beneath the fill point
Information that makes a recommendation more accurate
- Product formulation or safety data
- Normal filling temperature
- Minimum and maximum dose
- Acceptable fill tolerance
- Container and neck dimensions
- Required good packs per hour
