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.

Introduction Piston fillers measure and dispense free flowing products - such as thin and/or moderately dense liquids - onto a container. Each machine is equipped with one or more volumetric pistons. Each fill/release cycle consists of an intake stroke, where the product is withdrawn from the container or...

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

How Does A Piston Filler Work?

The principle of piston filling is actually very simple. At the beginning the valve is linked to the hopper and the piston cylinder, then the piston extracts the material from the hopper into the piston cylinder, then the valve turns to the filling nozzle (the valve is linked to the piston cylinder and the filling nozzle), and finally the piston...

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.

Pump Filler: The Ultimate Guide

We all know that a liquid filling machine is a kind of equipment that dispenses liquid/paste into bottles or other containers. In order to ensure that each bottle receives an equal amount of liquid/paste during the dispensing process, the filling machine will have a device or component specifically designed to measure. Common metering methods include gravity fillers based on time...

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.

How Does A Gravity Filler Work?

Gravity filling as the name implies uses gravity to complete the filling. Gravity filling machines allow packagers to fill the same volume of product into each bottle using the time-based filling principle. That's why it's also called a time gravity filling machine. A gravity filler has a hopper placed up above a set of nozzles, which is then filled with...

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.
