Electric airless screw pumps, such as the Wagner PlastCoat 1030, play an essential role in the application of coatings, particularly for high-viscosity materials such as plasters and renders. These machines combine efficiency, robustness and versatility, meeting the requirements of construction professionals.
1. What is an electric airless screw pump?
An electric airless screw pump is a spraying device that uses a helical screw (also called a rotor) to move material through a stator, creating sufficient pressure to spray coatings without the need for compressed air. This technology is particularly suited to materials with high viscosity or containing large fillers, such as coatings, mortars and mastics.

2. How a screw pump works
The operating principle is based on the interaction between the rotor (a helical screw) and the stator (an elastomer cylinder). As the rotor rotates inside the stator, cavities form and move longitudinally, carrying the material from the pump inlet to the outlet. This mechanism provides a constant, even flow, ideal for the uniform application of coatings.
3. Advantages of electric airless screw pumps
-
Versatility: Capable of handling a wide range of materials, including those with high particle sizes or fibres.
-
Consistent flow : Ensure even application without pulsation, improving finish quality.
-
Robustness: Designed to withstand the wear and tear associated with abrasive materials, they offer a long service life.
- Easy maintenance: Simplified design for easy cleaning and maintenance.

6. Safety and best practice
The use of electric airless screw pumps, such as Wagner PlastCoat, requires particular attention to safety instructions to ensure the protection of operators, equipment and the environment. Here are the main recommendations :
- Training and qualifications: Make sure that anyone installing, operating or maintaining the pump is suitably qualified and has read the operating instructions.
- Personal protective equipment (PPE): Wear appropriate PPE, such as gloves, goggles and respirators, to protect against splashing and inhalation of potentially harmful substances.
- Checking the equipment: Before each use, inspect the pump for wear, leaks or damage. Do not use the equipment if any defects are found!
- Pressurisation and depressurisation: Never dismantle connections or components when the system is under pressure. Ensure that the pump is correctly depressurised before carrying out any maintenance operation.
- Handling materials: Be aware of the properties of sprayed materials, particularly their flammability, toxicity or chemical reaction potential. Consult the relevant safety data sheets and follow the manufacturer’s recommendations.
- Working environment: Use the pump in a well-ventilated area to avoid the accumulation of potentially dangerous vapours. Keep the work area clean and free of obstructions to prevent accidents.
- Regular maintenance: Follow the manufacturer’s recommended maintenance schedule to ensure correct operation and prolong the life of the pump. Use only original spare parts to ensure compatibility and safety.
- Storage: After use, clean the pump thoroughly and store it in a dry place away from extreme temperatures and corrosive substances.
By following these instructions, you will help to ensure that your electric airless screw pump operates safely and efficiently, while protecting your health and preserving the performance of the equipment.
