Automatic Piston Volumetric Liquid Filler

Piston Liquid Filling Machines

Piston filling machines is best suited for viscous products such as paste, creams, and even chunky products with large particulates. Piston fillers are built to meet food grade standards and are commonly used in the food industry to fill heavy sauces, salsas, salad dressings, and other similar products. They are also used in other industries to fill cosmetic creams, shampoos, gels, wax, glue, grease and additional viscous products.

Piston fillers work by pulling a piston back in its cylinder which also draws in product from the supply tank or hopper. A check valve then changes position so that on the pistons down stroke the product is pushed out of the piston chamber, through the fill nozzle, and into the container. The volume of product is determined by the size of the piston cylinder and how far back the piston is drawn. This method of filling is very precise each and every time.

There are a number of advantages to using a piston filler. As a conventional mechanical filler it is one of the easiest to understand an use. It is also one of the more cost effective solutions for accurate filling of thick products. And because of there simple design they are easy to clean and maintain.

Generally speaking Piston filler are not typically used for thin free flowing products. While Accutek Piston Fillers are capable of handing free flowing products, its not recommended. Other considerations for piston fillers is that there fill cycle is limited by there cylinder size. A smaller cylinder can fill a larger container with multiple dose cycles but that will slow down the filling process. On the other end of the spectrum a larger cylinder can be made to deliver a smaller dose but the bigger the variance the less accurate the delivered volume becomes. Most customers typically look for piston fillers with an 8oz or 16oz piston. Accutek can build piston fillers with larger 32oz, 64oz, or 128oz cylinders should the project require it.

Low Production Volume

Semi-Automatic Piston Filler


Semi-Automatic Piston Fillers require someone to manually place and remove containers. Good operators can see speeds up to 30 containers per minute.

Average Production Volume

Automatic Piston Filler

In-line Automatic

Automatic Piston Fillers automatically place, index, and remove containers from a conveyor line. These systems are great for projects ranging from 10 up to 100 containers per minute.

High Production Volume

Rotary Volumetric Filler

High Speed Rotary

Rotary Piston fillers are NOT available. However Rotary Volumetric Fillers can deliver high speed filling of viscous liquids at speeds ranging from 100 up to 600+ containers per minute.
