Gravity Fillers

(49 companies)

Also called gravimetric fillers, these liquid filling machines dispense typically water-thin or low viscosity liquids from an upper chamber by dropping the product into a container, such as a bottle.

More on Gravity Fillers

Gravity fillers, also known as dense phase fillers and pressure filling machines, are used to fill containers with a wide range of products, including powders, granules and liquids. Gravity fillers are designed to provide a consistent and accurate fill, while simultaneously reducing waste and improving efficiency.


The principle behind gravity fillers is simple and is based on the law of gravity: the product is fed into a hopper placed above the filling area, which is then pressurized with air. The pressure, working with gravity, forces the product through a valve and into the container. The fill level is controlled by adjusting the pressure and the valve’s opening, allowing for precise and consistent fills, regardless of the material's characteristics.


One rather large perk to using gravity fillers is that they’re extremely versatile, which allows them to fill a wide range of containers, including bottles, jars, cans and bags. This makes them an optimal choice for manufacturers who need to package products in various different formats. Gravity fillers can also handle a variety of product mediums, from fine powders to dense granules.


Another feature of pressure fillers is their speed. These machines are capable of filling hundreds of containers per minute, making them an advantageous component in high-speed packaging lines. This speed is achieved through the use of advanced automation technology, which allows for seamless and precise control over the filling process.


On the other hand, smaller volume runs and emerging brands may not need the speed. Instead these smaller operations may use manual gravity fillers, which work perfectly well for their applications.


Accuracy is another benefit incurred through the use of this equipment. Pressure and valve controls allow for precise fills, which reduces waste and improves the overall product quality. This is especially important for manufacturers who need to meet strict quality standards or are producing high-value products.


One of the most common applications for gravity fillers is in the food and beverage sector. These machines are used to fill containers with products such as sugar, flour, spices and coffee, or liquid products such as juice, milk and water. In the pharmaceutical industry, gravity fillers are used to fill capsules and tablets with powders and granules.


Gravity fillers are also heavily used in the chemical and petrochemical industries. These machines can fill containers with products such as fertilizers, pesticides and even hazardous materials like acids and solvents. In these applications, the accuracy and consistency provided by gravity fillers is crucial for safety and regulatory compliance.


Overall, gravity fillers can be an essential component in many packaging processes. They provide accurate, consistent fills while reducing waste and improving efficiency. Their versatility and speed also make them an ideal choice for manufacturers who need to package products in different formats and at high volumes.
