Volumetric Filling Machine

Your Ultimate Guide to Understanding Volumetric Filling Machine

Most modern production lines, especially beverage, cosmetics, and pharmaceuticals, are often equipped with automated machines. These factories don’t have to pour liquids manually into each container. They commonly use liquid filling machines to lessen human intervention. Among its types is the volumetric filling machine. This article aims to in-depth and clear information about volumetric filling machines. We will also discuss its key elements including its types, features, advantages, and more.

Volumetric Filling Machine – The Overview

Volumetric filling machines are a type of liquid filling machine. It fills containers with free-flowing products such as pastes or liquids. This filling equipment is usually used in packaging industries to fill each container with a specific amount of liquid products.

These types of fillers work through a volume-based approach. Thus, no matter the shape discrepancy of the containers, this machine can fill a consistent volume. However, volumetric filling machines require the operator to perform some manual adjustments.

Different Types of Volumetric Filling Machines and Their Working Principles

The working principle of a volumetric filling machine mainly depends on its type. Knowing the different types of these machines can help you understand how each of them functions. It will also help you choose the right machine depending on your container shape and size as well as product characteristics.  There are different types of this machine including:

Volumetric Pump Filling Machine

As its name implies, these machines move the products from the tank into the containers using a variety of pumps. The fluid’s positive displacement process moves the lobe or gear pump parts, allowing the liquid to flow.

Volumetric pump fillers are highly suitable for liquids with higher viscosity. Higher viscosity fluids cannot clog the moving parts of the machine. A peristaltic pump with rollers and tubes is used for isolating the pump’s moving part. This is to ensure a sanitary production process.

Gravity-Fed Volumetric Filling Machine

These types of machines use gravity force to fill liquid products into the containers. The bulk supply of liquid products is poured into the containers from a tank over the machine’s filling head. The valve is individually timed to release an accurate amount of liquid products.

Gravity volumetric filling machines are ideal for packaging thin viscosity liquid products. It is also suitable for foaming products due to its bottom-up capabilities. These machines are low-noise and can handle wide range of temperatures.

Piston Volumetric Filling Machine

These machines are integrated with a valve that opens to release the liquid from the hopper and flows down into the cylinder. When the piston cylinder is full, the liquid products are forced into the nozzles to fill the container.

Piston volumetric filling machines can handle a wide range of liquid densities and viscosities. Thus, providing a precise and accurate volumetric filling process. It can fill containers with creams, thick liquids, and large particle products.

Advantages of Volumetric Filling Machines

Volumetric filling systems provide a range of advantages compared to manual filling.


Due to its flexibility, a volumetric filling machine can be used for filling different containers including tubes, bottles, glass jars, and more.


These machines allow producers and factories to increase productivity. It also helps in reducing labor costs. Some volumetric filling machine models have automated labelling function. Thus, increasing production efficiency.

Easy to Use

Volumetric fillers are user-friendly machines. Most of these machines have semi or fully automatic functions. For semi-automatic, operators are required to put the containers under the machine nozzle. Then, set the specific product volume and press start to begin the filling process. Meanwhile, automatic volumetric fillers are intuitive to set up and will do all the filling stages.

Quality Assurance

Through these machines, operators can closely monitor the amount of liquid products filled in the containers through nozzles. Thus, maintaining a consistent quality control.

Downside of a Volumetric Filling Machine

Although volumetric filling machines provide a lot of advantages, they also have a few downsides including:


Commonly, a volumetric filling machine is expensive. It is an expensive investment especially for small business. Thus, small business owners should assess the machine’s cost and benefits on their business.

Fill Levels

Despite of its high accuracy, volumetric filling machine can still leave an apparent small fill level difference.

Products that a Volumetric Machines Fill

Volumetric filling machines can fill different containers with a variety of products such as:

  • Soda
  • Alcoholic beverages
  • Water
  • Yogurt
  • Toothpaste
  • Pharmaceutical vials
  • Paints
  • Beer, and more


Using a volumetric filling machine can increase your productivity and efficiency. This can fill containers with high speed and accuracy. It can also be used in different industries including food and beverage, pharmaceuticals, personal care, cosmetics, and more. Understanding the different types of volumetric fillers will help you choose the right one for your business.
