How Do Liquid Filling Machines Work?

Liquid filling machines are designed to efficiently and precisely dispense liquids into containers, ensuring consistency and minimizing waste. While the exact mechanics can vary depending on the type of machine and its application, here’s a general overview of how filling work:

  1. Container Placement: Empty containers are placed on the machine, often via an operator placed manually or fed bottles by bottle unscrambler.
  2. Liquid Filling Assembly: Depending on the machine type, liquid is filled from filling nozzle to the containers using different methods:
    • Volumetric Filling: the principle of volumetric filling is based on accurately measuring and dispensing a specific volume of liquid into the containers. Piston pump filler control the volume of liquid by drawing in a precise amount during the intake stroke
    • Overflow filling: the principle of overflow filling is designed to ensure consistent fill levels in containers, making it particularly useful for products packaged in transparent bottles.
  3. Container Movement: After filling, containers move along the conveyor to the down-stream equipment, such as capping machines or secondary packaging equipment.


Key Mechanical Components

Filling machines consist of several key mechanical components that work together to ensure precise and efficient filling processes.

  • Hopper: Store liquid to be dispensed, when the material is run out of, it will inform the liquid feeding pump to supply liquid into the filler tank.
  • Filling Nozzles: For dispense liquid into containers, it can be designed according to bottle opening
  • Filling Mechanism: Flow meter, piston pump, rotary lobe pump, gear pump and overflow are used based on liquid viscosities and characteristics
  • Conveyor system: Transports bottles through the filling, capping, labeling and secondary packaging machines. The speed is adjustable.
  • PLC control system with touch screen


Types of Filling Mechanisms

Filling machines have a type of semi-automatic or automatic filling machine, the difference between the two types of machines is capable of reducing the manual job and saving the time for packaging to improve the production efficiency.

Liquid filling equipment can be used in a wide range of industries, such as food and beverage, chemical,household and other industries involved in manufacturing liquid products. There are various filling machines available to choose from below.

  • Flow meter fillers - A wide range of industrial chemical products and household dosing.
  • Piston pump fillers – Perfect for thick pastes, creams, and highly viscous products.
  • Rotary lobe pump fillers - Ideal for a wide range of filling volume
  • Gear pump fillers - Designed for lubricant oil
  • Overflow Fillers – Ensures consistent fill levels, ideal for clear containers.
