What is Volumetric Filling Machine?

A volumetric filling machine is a type of filling equipment used in packaging and processing industries for filling containers with precise volume of liquids, pastes, or other free-flowing materials. It works by measuring the volume of product dispensed into a container, rather than the weight or height within a bottle.

Types of Volumetric Fillers

Three popular types of volumetric filling methods: piston filler, positive displacement pump filler, and gravity filler. Each type of equipment can be semi-automatic or fully automatic or even high-speed rotary.

Volumetric Piston Filling Machine

A volumetric piston filling machine is a type of liquid filling equipment that fills containers with a specific volume of liquid using a piston and cylinder mechanism. The machine accurately dispenses the liquid by measuring the displacement of the piston in the cylinder, ensuring consistent and precise fill volumes. It is commonly used in industries such as pharmaceuticals, cosmetics, and food and beverage.

Positive Displacement Pump Filler

A positive displacement pump filler is a type of liquid filling machine that uses a pump to transfer the liquid from a supply source to the container to be filled. The pump creates a vacuum which pulls the liquid from the supply source, then pressurizes the liquid to fill the container. This type of filler is capable of handling thicker liquids, and is often used in industries such as food and beverage, chemical, and personal care. The positive displacement pump ensures accurate and consistent fills, with the ability to handle a wide range of viscosities and fill volumes.

Volumetric Timed Gravity Filler

A volumetric gravity filler is a type of liquid filling machine that uses gravity to dispense a precise volume of liquid into containers. The machine has a container that holds the liquid and a control valve that regulates the flow of the liquid. The valve opens to allow a specific volume of liquid to flow into the container and then closes, controlling the precise fill volume. Volumetric gravity fillers are commonly used in industries such as food and beverage, pharmaceuticals, and cosmetics. They are relatively simple, cost-effective and efficient for low to medium-volume filling operations.

Volumetric Filling Machine Principle

Volumetric Piston Filler

A piston filler measures and delivers the product to the container by the action of a single piston for each filler head. The volume of product delivered into the container is determined by the volume of the filling chamber in which the piston is operating. This volume can be changed by adjusting the length of the piston’s stroke. As the stroke is lengthened, the volume of the chamber is increased, and as the stroke is shortened, the volume of the chamber is decreased

Positive Displacement Pump Filling Machine

The diaphragm type volumetric filler uses a flexible diaphragm and pneumatic pressure to move premeasured amounts of product from the supply tank into a controlled volume chamber and into the container.

The diaphragm volumetric filling systems are generally used to fill small-necked bottles with relatively expensive products because of their high level of accuracy and the small loss of product in filling.

Volumetric Timed Gravity Filling Machine

The volume of product in each fill can also be regulated by controlling the amount of time the product flows at a constant rate through a standard sized tube into the container. Rotary pumps are used for volumetric filling by regulating the operating interval of the pump to control the amount of product that is delivered.

Advantages of Volumetric Filling Machine

Volumetric filling machines have revolutionized the packaging industry by offering a faster and more precise method of filling containers with liquids, pastes, and other viscous materials. These machines are widely used in various industries, including food, pharmaceutical, cosmetic, and chemical industries. The following are some of the benefits of using a volumetric filling machine.

♦ Accuracy:

One of the main advantages of using a volumetric filling machine is its accuracy. Unlike other filling machines, volumetric fillers are designed to dispense a specific volume of product with high precision. This ensures that each container is filled with the exact amount of product, reducing waste and ensuring consistent product quality.

♦ Speed:

Another advantage of using a volumetric filling machine is the speed at which it can fill containers. These machines are designed to fill containers quickly and efficiently, reducing production times and increasing output. This makes them ideal for high-volume production runs and helps to keep up with the demands of the packaging industry.

♦ Flexibility:

Volumetric filling machines are designed to be flexible and can be easily adjusted to handle different types of products and container sizes. This makes them suitable for use in various industries and ensures that they can be adapted to meet the specific needs of each application.

♦ Reduced Labor Costs:

By automating the filling process, volumetric filling machines can significantly reduce labor costs. This is because they require fewer operators to run than other filling machines, reducing the need for manual labor and increasing productivity.

♦ Easy to Operate:

Volumetric filling machines are designed to be easy to operate, making them suitable for use by operators with little or no experience. They are also easy to maintain, with minimal downtime required for cleaning and maintenance, helping to reduce overall operating costs.

♦ Safe and Hygienic:

Volumetric filling machines are designed to be safe and hygienic, making them suitable for use in the food and pharmaceutical industries. They are constructed with food-grade materials, and their design ensures that product contamination is minimized, reducing the risk of product spoilage and ensuring that products are safe for consumption.

In conclusion, volumetric filling machines offer a wide range of benefits that make them an essential part of the packaging industry. Their precision, speed, flexibility, and ease of operation make them ideal for a variety of applications, and their safe and hygienic design ensures that they are suitable for use in industries where product safety is a concern. If you're looking for a cost-effective, efficient, and reliable filling solution, consider investing in a volumetric filling machine.

Volumetric Filler VS Level Filler VS Net Weight Filler

	Volumetric Filler	Level Filler	Net Weight Filler
Scope of application	The volumetric filler is best suited for products with consistent density and flow properties, such as liquids, pastes, and some powders.	The level filler is suitable for products with low viscosity and consistent density.	The net weight filler is best suited for products with variable densities, such as powders and granules(Of course liquids can also be used).
Advantages	It offers precise and consistent filling volumes, making it ideal for applications where the precise dose is important, such as pharmaceuticals or food.	This type of filler is relatively simple to operate and is ideal for applications where speed and efficiency are important.	This type of filler provides precise and consistent filling weights, making it ideal for applications where the precise dose is important.
Disadvantages	This type of filler is not suitable for products with varying densities, as it may not accurately fill the container.	The level filler may not provide precise filling volumes and may not be suitable for applications where precise dosing is important.	The net weight filler can be more complex and time-consuming to operate than other fillers, and may not be suitable for applications where speed and efficiency are important.
