System 4


Select 4 – Recirculating / Model V 1000

  • This system is preferred for use in particular with materials which will settle out or dry quickly. This is why these materials are kept in circulation. A dual diaphragm pump is used for this purpose.
  • This is a small spray system with a material pressure tank, to apply about 70,000 dots (dots 5 mm in diameter) or 4,500 meters of lines (5 mm wide)
  • Simple operation, low maintenance
  • For dots of from 3 to 30 mm in diameter
  • A solenoid valve is used to trigger the spray gun. WALTHER PILOT can also deliver the controls, upon request.
  • We would be happy to provide planning and assembly services, right through to integrating the system into your assembly line.


  • Marking spray gun, Model 20-365, with pull rod for manual activation (e.g. for spray trials), recirculating version Body: nickel-plated brass; nozzle and needle: stainless steel; nozzle sizes: 0.3, 0.5, 0.8, 1.0, 1.2, 1.5 mm in diameter
  • MDG 1 material pressure tank, 1,100 ml, stainless steel, max. 3 bar, recirculating version
  • Solenoid valve, 3-port, 2-position, 24 V DC; other voltages available
  • Solenoid valve, 2-port, 2-position, 24 V DC; other voltages available
  • MBP 2812 diaphragm pump Acetyl (other versions possible)
  • Pneumatic control cabinet with pressure gauge To connect one pressure tank, one marking gun, one diaphragm pump
  • Hose kit (2 meters), incl. fittings for both the air and material hoses


  • Holders for marking guns
  • Agitators and fill level measurement sensors
  • Color sensors and measurement transducers to monitor functions
  • Control cabinets / pneumatic control cabinets n Integration of the system into your assembly line
  • Compressed air manifold instead of pneumatic controls

System Variants

Depending on production requirements, material delivery to a marking system may comprise multiple material pressure tanks and diaphragm pumps. We will work out a concept customized to suit your operations.

MDG 2 (1,800 ml), MDG 3 (2,500 ml), MDG 4 (3,100 ml) tanks or tanks from the LDG series may be used instead of the MDG 1 material pressure tank.
