Our piggable system is used to:

  • Reduce the needed quantity of paint to load in a circulating
  • Allows colour ​changing in a short time.

The paint is pushed with a small cylinder (pig), this pig is equipped with seals to clean the internal surface as it moves through the pipe. 

4 pigs are needed to operate the system. Between the first two pigs, paint circulates then the 3rd pig pushes a first quantity of solvent which is used to perform a first cleaning of the pipe. 4th pig pushes a second amount of solvent which terminates the cleaning circuit.

Highway valve are 3 ways valves which are used to feed robots with paint, then they allow the rinsing of the flexible that feeds the robot once the cycle is complete.

At the end, the remaining paint not used and still in the pipe will be recovered into the paint drum.


Automatic system allows to pig and clean completely the line without any operators intervention, unless for loading and unloading paint drums, and changing the pigs when required.


Tubes are in stainless steel with a constant diameter and smooth connections to ensure the perfect piging function.

Pigs are designed to maximize the paint recovered Vs an optimum MTBF.
MTTR in the full automatic system is not an issue.
Seals used are specific for solventborne or waterborne paint


The load station is used to insert a pig into the system or to take out when a pig is damage.

Modular conception

Our solution is composed of:

  • An automatic flushing station used to load the paint into the pipe, this station permit also to clean automatically the cover. 
  • A testing and cleaning station used to test and clean the pig
  • A storage station used to stock pigs
  • A recovery station used to load and unload pigs into the system. 
  • A selection valve used to send pig into recovery station or storage station following the pig test result.
  • A departure station used to send the pig into the pipe and select paint/solvent or air to push it.
