1. According to the type of booster pump, there are plunger pump type, diaphragm pump type, etc.
2. According to the form of power, there are pneumatic, electric, internal combustion engine, etc.
(1) Pneumatic airless spraying machine: driven by an air compressor.
Its main features are: no need for electrical appliances, high safety; High pressure, reaching over 40MPa, suitable for various solvent based coatings, water-based coatings, high viscosity thick paste coatings, and all conventional coatings. For example, thick and thin fireproof coatings, crack resistant mortar, insulation mortar, real stone paint, etc.
(2) Electric airless spraying machine: driven by an electric motor.
Its main characteristics are: easy to carry and apply, mainly used in the construction industry for painting, putty spraying, coatings, and general anti-corrosion coatings, with less application in heavy-duty anti-corrosion coatings.
(3) Internal combustion engine type airless sprayer: driven by gasoline or diesel engines.
Its main characteristics are: construction sites with inconvenient electricity usage, suitable for outdoor mobile construction, such as road marking, etc.
