Automatic ink supply system

The paint supply system is used to automatically supply automatic spraying machines or manual spraying stations with paints. The system can also be designed to process water-based or solvent-based coatings. The color change can be performed manually or by pneumatic control of the color change valves. During color change, a flushing process takes place to remove paint residues in pipelines, valves and in the spray gun.


The paint is stored in 25 l or 200 l material containers. The system can also be adapted to other container sizes.

For easy changing of the material containers, the equipment is positioned on lifting devices.
The paint is conveyed to the pick-up points via hose and pipe lines. The necessary conveying pressure is generated by compressed air-driven pumps.

A range of additional equipment is available to improve the processing properties of the paints, for example:

  • compressed air-driven agitators can be installed in the material tanks, double filter groups can be installed in the material lines
  • the material lines can be designed as circulation lines up to the material change valves
  • The pumps can be equipped with pressure compensation tanks to compensate the pressure surges.

The paint supply systems are operated and controlled exclusively with compressed air. The independent compressed air driven pump sucks the paint out of the material container. Via the pressure compensation tank and the control valve, the paint is filtered in the double filter groups. From the double filter group, the material enters the stainless steel pipe via a flexible hose line. The paint flows through the stainless steel pipe to the color change valve.

The color change valves are controlled pneumatically. Unused paint is returned to the material containers via a circulation line. When the color change valve is open, the coating flows to the material pressure regulator and from there to the automatic spray gun. The material pressure required at the automatic spray gun is set continuously at the material pressure regulator. The control is pneumatic.
