Filling by Viscosity
From Water-Thin to Paste-Thick: The Right Machine for Every Product
Viscosity is the biggest factor in choosing a filling machine. Thin liquids flow freely, while thick products need positive displacement to stay accurate. Find your product below.

Product type
Example products
Best technology
Why it works
Thin, water-like
Water, juice, solvents, thin oils
Gravity or overflow filling
Fast and simple. Overflow gives a consistent fill level in clear bottles.
Medium Thick
Liquid soap, cooking oil, syrups, lubricants
Pump or piston filling
Handles changing viscosity and a wide range of fill sizes.
Thick
Sauces, creams, gels, honey
Lobe Pump or Piston
Positive displacement keeps every dose accurate, even when the product flows slowly.
Very thick or paste
Pastes, ointments, thick sauces, products with particulates
Lobe Pump or Heavy-duty piston filling with wide-bore nozzles
Moves dense products and particles without clogging.
Foamy
Detergents, shampoos, cleaners
Overflow or bottom-up filling with diving nozzles
Fills from the bottom of the container to keep foam down.
Corrosive or aggressive
Acids, bleach, strong cleaners
Pump or piston filling with chemical-resistant parts
Stainless steel or chemical-resistant seals protect the machine and the product.
How to choose a liquid filling machine
-
How thick is your product? Viscosity decides the filling technology.
-
Does it foam, contain particles or attack seals? Foamy, chunky or corrosive products need specific nozzles and materials.
-
What is your target output? Give us your units per hour now, and in two to three years.
-
What containers will you fill? Bottle shape, neck size and container range affect the nozzle and changeover design.
-
How will you grow? Choose a machine that can be upgraded with capping, labelling and conveying.
