Filling Machines

Filling can be devided into two main technologies:

  • Volumetric
  • Gravimetric

Volumetric filling machines

Volumetric filling machines are based on a self-priming cylinder. A piston is moving inside this cylinder and the stroke length and diameter of the piston determines the filling volume.

Gravimetric filling machines

Gravimetric filling machines are measuring the exact weight using a valve that is placed over an electronic scale. The scale in combination with the weighing program controls the valve operating resulting in a weighing process.

Decision conditions


(By volume)


(By weight)

Difficult product properties

(Air bubbles, large particles, etc.)

Large volumes

(Over 20 liters)

Small medium volumes

(20 liters or less)

Budget cost

(Gravimetric is generally more expensive)

Filling Applications

Gemini Techniek produces customer-specific filling applications for various industries.

The industries for which Gemini Techniek supplies the filling applications are:

Paint & Coatings Industry

The paint & coatings industry requires semi- & fully automatic filling machines to fill large batches into the can (sales packaging). Throughout the years we have successfully developed stand-alone filling machines and filling machines integrated in an automatic process that can combine conveying systems with automatic lid placing and closing.

Our filling machines are also able to handle high viscosity products with or without granulates like texture, wall plasters etc. Special pump execution, materials of construction and valve design make our systems very robust and durable.

Paint & coatings industry
Chemicals industry

Chemicals Industry

The chemical industry has a wide range of application: e.g. all kind of cleaning liquids, oil, solvents etc. All these applications require a different approach. A cleaning liquid for example can foam very strongly when filling in a bottle or can. This would require a sub-level filling lance to prevent this foaming.

Also chemicals like some solvents can foam when filling it too quickly. Chemicals may require special safety measures to guarantee a safe working place. Toxics or flammable products can require venting systems. This kind of problems made us decide to design systems that fulfils all these requirements.

Ink Industry

Especially liquid printing inks (water- and solvent based) are very similar to paints and coatings and the required filling systems are therefore about the same as for paint & coatings.

Ink industry
Adhesives and sealants industry

Adhesives & Sealants Industry

The adhesives and sealants industry is similar/close to the paint & coatings industry. Recipe based dispensing of several components into a container. All our dispensing machines are able to produce large batches and/or small batches in the range between approx. 1 kg. up to 3.000 kg.

Explosion proof

The filling machines can be executed in explosion proof according to ATEX in category 1 / 2/ 3. It can also be executed in Class 1 Division 1 (or 2). Gemini can provide their machine in the right category according to your environment.
