Basic system components: œ Drip tray in accordance with Water Protection Laws œ Pneumatic, twist-proof lift for drum cover acting in both directions (available for 30-, 60- and 200-litre drums and barrels) œ Agitator (electric or pneumatic) œ Pump with material filter œ Switch (on/off) œ Compressed air supply In addition to diaphragm pumps, piston pumps can also be used, e.g. for higher-viscosity materials. Drum transfer systems Stirring station for consistently high material quality The coating material is prepared while it is still in the delivery drum, to ensure that it is in an optimum...

Drum transfer systems Detailed view: open heating jacket This not only guarantees quality assurance due to exactly reproducible production conditions, it also protects the environment. Since the material properties are adjusted mainly by heating and less solvent has to be added, VOC emissions are reduced. Drying times can also be considerably shortened. Depending on the application profile, investment in additional heating systems soon pays off. Further possibilities for material temperature control: œ Material heaters œ Heating hoses œ Heating bands œ Heating collars œ Pipe heaters System...

SprayPak – the versatile system The PILOT SprayPak material supply unit with a double diaphragm pump is mounted in a spacesaving manner on a drum cover or bracket. SprayPak offers a clear overview of all the necessary pneumatic control elements. The system has a special pneumatically powered fine regulator for the material pressure, ensuring excellent pulsation-free atomisation. A material filter is also integrated. Particularly economical spray coating with a finish that meets the highest quality requirements is best achieved using PILOT medium-pressure spray guns. Transfer rates similar...

Operation of a circulation system The material is pumped from the tank via a ring circuit to the point(s) of application. After the final point of application, the material flows back to the tank via a backpressure regulator. As a result, the material is constantly kept in motion and is not able to settle in the pipes. Low-pressure circulation systems In these systems, diaphragm pumps are used to supply the coating material to the application equipment. Air-atomising spray guns are used. Advantages: 1. Constant colour shade, constant viscosity during application – high process reliability....

The equipment solution to suit the customer’s needs also includes mounting panels for fixing pumps or Spaypaks, air fittings, solenoid valves, etc. Complete solutions for application equipment are also available: automatic spray guns, brackets, reciprocating units or linear drives, hoses, compressed air supply. As a full system supplier, WALTHER PILOT also offers the best application equipment to suit your needs, e.g. spray guns for manual or automatic operation. The automatic circulation spray gun PILOT WA 510 shown here is also available as an HVLP version PILOT WA 530. If space is...

Material flow diagram of a highpressure circulation system: Tank station for high-pressure circulation operation with a lift for dum covers for 200-litre drums and a paint mixing tank Type FMB 250 (or larger) from WALTHER PILOT. Level monitoring with automatic refilling is provided by the pulse generator of the min./max. sensor. The diaphragm pump on the drum cover is activated when the level in the paint mixing tank reaches the minimum, thus eliminating interruptions in the coating process caused by manual filling. Furthermore, the properties of the coating material can be adjusted in a...

Circulation systems for spray marking and spray coding WALTHER PILOT supplies marking blocks for spray marking and spray coding, for example for marking steel slabs, sheet, billets and much more besides. Special spray guns are also available for marking (e.g. defect marking) as part of quality assurance. Whenever you need to spray small quantities of material with high precision, WALTHER PILOT offers the optimum complete system to suit your needs. Integrated flushing gun A small pressure tank is provided to supply the spray gun with cleaning agent. This is used to externally clean the...

Decisive advantages Pressure tanks offer the ideal opportunities for material supply, as the material is transferred to the application equipment without pulsation. At the same time, they guarantee that the material is safely stored. The wide range of products manufactured by WALTHER PILOT offers optimum solutions whatever your needs, no matter whether you want to spray paint, lacquer, primer or other materials. Pressure tanks are especially suitable for use with abrasive materials, as they have virtually no wearing parts. They are also the ideal choice for shear-sensitive materials....

This is particularly useful when lids are fitted with agitators, level sensors, etc, which make manual lifting a difficult task. The new design of the lifting system makes filling the tank much easier and the lid is securely positioned. What is more, sensitive accessory components such as level sensors are effectively protected against mishandling. The pneumatic lift is perfectly suitable for use with the following tank sizes: Aufrührstation mit Heber für Druckbehälter Material pressure tank with lift for cover WALTHER PILOT now offers the perfect solution for many handling problems: a...
