Liquid Filling System or Liquid Filling Machines  are specialized pharmaceutical filling machines used to to fill bottles, vials, ampoules and other containers with pre-determined quantity of liquids. These machines adopt a volumetric piston filling mechanism for smooth liquid filling. Machines are also easy to operate and are able to fill precise quantity of liquid into containers. This filling equipment allows adjustment of different sized bottles without changing parts and also have 'No Bottle-no fill' mechanism, almost similar to a tube filling machine or vial filling machine. Most machines meet the GMP norms. The output of these machines depend on the feature, whether they are semi automatic or fully automatic.

The Choice of Filling Machine Depends on:

• The range of viscosity of the liquid
• Temperature
• Chemical compatibility
• Particulate size
• Foam characteristics and
• Hazardous environment considerations.

Different factors need to be considered while purchasing filling machines which we have discussed in out article Buying Tips for Liquid Filling Machines.

Commonly Used Filling Machines

• Overflow liquid filling machines: These are commonly used in small bottle filling operations and the machine is also able to handle liquids with medium viscosity.
• Servo pump liquid filling machines: These machines are very versatile liquid filling machine capable of filling nearly any type of product that can be pumped.
• Peristaltic filling machines: This specially designed filler machine is used to fill liquids of high value and small volume of liquids fills with high accuracy.
• The gravity liquid filling machines: This is the most economical type of liquid filling machine for a limited range of applications.
• Piston liquid filling machines: These machines are one of the oldest and  most reliable types that are used in the packaging industry.
• Net weight liquid filling machines: This type of filler is best suited for liquids that are required to fill in bulk quantities.
