Automatic Piston Filling Machine


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 Each fill/release cycle consists of an intake stroke, where the product is withdrawn from the container or hopper and taken into the product cylinder. The down stroke commences as soon as the product cylinder has reached its predetermined fill level. The piston pushes the product out of the cylinder and into the container.

Our piston fillers provide clean drip free depositing and adds precision in your product lines. We configured our piston fillers to deposit accurate amounts of sauces, stews, batters, meat/sauce mixtures, and pastes every single time. As a result, our piston fillers and depositors deliver the highest product fill accuracy, with the lowest level of product degradation in the industry.

Spills, drips, and container overflows may be common in food filling lines, but not when you use piston fillers from VKPAK. What’s more, your staff will have more time on their hands as our equipment doesn’t need looking after every minute of the day. We make sure our machines do as they should: Enhance your process so your workers can be free to perform other, more important tasks.

1. Servo Drive System

The VK-PF series volumetric filling system utilizes the delicate servo drive system to control the main filling structure, achieving high stability and precise positioning. With the vertical movement of the filling piston provides long term energy saving and also effectively reduces machine load rate.

2. Tool-Free Adjustment

Adjustments can be made through the PLC, completely tools-free, giving users a fast and efficient result. The delicate servo control system design provides options for surface layer liquid filling, bottom layer liquid filling, and bottle neck (opening) filling accordingly with different types of liquids.

3. High Accuracy

The delicate servo system controls the filling amount through precise piston strokes, providing high filling accuracy. The piston is intelligently designed with an adjusting mechanism to enable users to obtain ultimate higher accuracy.

4. High Adaptability

The Automatic Servo Filling Machine can be used in food, pharmaceuticals, chemicals, cosmetics, and other industries.

Lubricant Filling Machine

Lubricant Filling Machine

Summary A lubricant is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces. The property of reducing friction...
Honey Filling Machine

Honey Filling Machine

Summary Honey is a sweet, viscous food substance made by honey bees and some related insects, such as stingless bees. Bees produce honey from the sugary secretions of plants or from secretions of other insects, by regurgitation, enzymatic activity, and water evaporation. Honey filling applications require heavy-duty machinery that...
Sauce Filling Machine

Sauce Filling Machine

Summary In cooking, a sauce is a liquid, cream, or semi-solid food, served on or used in preparing other foods. Most sauces are not normally consumed by themselves; they add flavor, moisture, and visual appeal to a dish. Sauces need a liquid component. Sauces are an essential element in...
