General view of application 

Description of unit

Dilutable lacquers and paints or those containing solvents, two-

component coating materials, dispersions, latex paints.
No other materials should be used for spraying without WAGNER’s

approval.

Filtering
Despite suction filter and insertion filter in the spray gun, filtering of 

the coating material is generally advisable.
Stir coating material before commencement of work.

Viscosity
With this unit it is possible to process highly viscous coating materials 

of up to around 25.000 MPa·s.
If highly viscous coating materials cannot be taken in by suction, they 

must be diluted in accordance with the manufacturer’s instructions.

Two-component coating material
The appropriate processing time must be adhered to exactly. Within 

this time rinse through and clean the unit meticulously with the 

appropriate cleaning materials.

Coating materials with sharp-edged additional materials
These have a strong wear and tear effect on valves, high-pressure 

hose, spray gun and tip. The durability of these parts cane be reduced 

appreciably through this.

The main areas of application are thick layers of highly viscous 

coating material for large areas and a high consumption of material.
A piston pump takes in the coating material by suction and conveys it 

to the tip. Pressed through the tip at a pressure of up to a maximum 

of 221 bar (22,1 MPa), the coating material is atomised. This high 

pressure has the effect of micro fine atomisation of the coating 

material.
As no air is used in this process, it is described as an AIRLESS process.
This method of spraying has the advantages of finest atomisation, 

cloudless operation and a smooth, bubble-free surface. As well as 

these, the advantages of the speed of  work and convenience must 

be mentioned.

In the following there is a short description of the technical 

construction for better understanding of the function.
WAGNER ProSpray units are electrically driven high-pressure spraying 

units.
A gear unit transfers the driving force to a crankshaft. The crankshaft 

moves the pistons of the material feed pump up and down. 
The inlet valve is opened automatically by the upwards movement 

of the piston. The outlet valve is opened when the piston moves 

downward.
The coating material flows under high pressure through the high-

pressure hose to the spray gun. When the coating material exits from 

the tip it atomizes.
The pressure regulator controls the volume and the operating 

pressure of the coating material.
