A simple Guide to Gravity Filling Machine



Gravity filling is the most basic way of filling. Gravity filling machines have a simple design and operation that allows them to function with little maintenance. The highest, central component of the machine is the feed tank (technically termed the filling bowl). 

The gravity filling machines operate on certain principles that we are going to see later in this article. Overall, we are going to look at the different parts of the gravity filling machine, their functions, principle operations and how the machine functions in general. Let’s get into it!

Components of a Gravity Filling Machine

Every functional filling machine has different components that enable it to meet its operations with ease. The gravity filling machine is no exemption. The following are the major components of the gravity filling machine:


The frame is used as a support for the machine. In most cases, they come in as either portable or fixed in production.

Filler Bowl

It is also referred to as a tank. It is the upper central part of the machine. It is used for products that return from the overflow nozzle.

Product Supply Tank

As the name suggests, the product supply tank is used to hold content, from which they flow through a nozzle, into the containers.

Filling Valves

Thye open and close to allow liquids to flow.

Product pathway and Nozzles

The product must be transported from the supply tank to the bottles and containers that are waiting. The pipes, tubing, and nozzles that are utilized to achieve this aim are referred to as the product route.

Gravity filling is the most basic way of filling. Gravity filling machines have a simple design and operation that allows them to function with little maintenance. The highest, central component of the machine is the supply tank. At every receptacle filling point, filling stems are connected to the bowl’s lower part. 

The filling bowl has a vent tube that projects upwardly to a point above the liquid level. To begin the filling process, the platform raises the container until it comes into touch with the filling stem.

After that, the platform raises the receptacle against the stem, which opens the filling valve. The liquid flows into the receptacle when the filling valve is open. The air in the receptacle escapes through the vent tube and into the area above the filling bowl’s liquid. Despite the fact that the container is nearly full, the liquid continues to pour in.

The surplus liquids accumulate until it achieves the same elevation as the liquid level in the bowl in the vent tube. There is no spillover of liquid from the containers into the bowl since the vent tube reaches beyond the liquid level in the bowl. If the substance is frothy, the froth will rise beyond the liquid level in the bowl in the vent tubing.

As a result, gravity fillers are rarely utilized in foamy products. The container is descended from its filling position and the filling valve is closed at a specified time after it has been full. Several methods are used to evacuate liquid that has accumulated in the filling stem from the vent tube.

For a restricted range of uses, this is the most cost-effective form of filling machine. It works particularly well with caustic substances.

Gravity filling machines are perfect for filling free-flowing goods with a simple timer. Depending on the product and the receptacle being filled, these machines can employ a range of filling nozzles.

Gravity fillers, unlike overflow machineries, do not use a recirculating mechanism and do not require specialized injectors. As a result, for low-densities, voluntary-flowing materials, the gravity filler is a cost-friendly alternative.

Applications of Gravity Filling Machines

This sort of filler works well with liquids that have very thin densities and don’t alter with temp or batch variance. This machine is also suitable for situations where liquid recirculation in the fluid route is not desired. Although this sort of filler is often used on non-foaming materials, sub-surface capabilities can restrict and regulate foam.

Water, solvents, alcohol, specialized chemicals, paint, inks, and corrosive chemicals such as acids and bleach are all samples of the products that the gravity filling machine can be used as a filling solution. They all have one similar thing, their densities are low, which is precisely what the gravity filling machine is customized to deal with.


The working principle of a quality gravity filling machine is quite simple. That is why at Leva Pack, we ensure that all our filling machines are beyond the industry standards. Contact our team and allow them to guide you through the whole selection and customization process. Good Luck!
