Super Finish 23 PLUS

GENERAL VIEW OF APPLICATION
3. DESCRIPTION OF UNIT
3.1 AIRLESS PROCESS
The main area of application are thick layers of highly viscous
coating material.
At the Super Finish 23 PLUS unit a diaphragm pump takes in
the coating materials and transports it via a high-pressure
hose to the spray gun with the airless tip. Here the coating
material atomizes since it is pressed through the tip core at
a maximum pressure of 25 MPa (250 bar, 3625 psi). This high
pressure has the eect of micro ne atomisation of the coat-
ing material.
As no air is used in this process, it is described as an AIRLESS
process.
This method of spraying has the advantages of nest atomisa-
tion, cloudless operation (depending of a correct unit adjust-
ment) and a smooth, bubblefree surface. As well as these, the
advantages of the speed of work and convenience must be
mentioned.
3.2 FUNCTIONING OF THE UNIT
The following section contains a brief description of the tech-
nical construction for better understanding of the function:
Super Finish 23 PLUS is an electrically driven high-pressure
paint spraying equipment.
The electric motor (1) drives the hydraulic pump via planetary
gears (2). A piston (3) is moved up and down so that hydraulic
oil is moved under the diaphragm (4) which then moves.
In detail:
The downwards movement of the machine opens the disk in-
let valve (5) automatically and coating material is sucked in.
During the upwards movement of the diaphragm, the coating
material is displaced and the outlet valve opens while the inlet
valve is closed.
The coating material ows under high pressure through the
high-pressure hose to the spray gun and is atomized when it
exists from the tip.
The pressure control valve limits the set pressure in the hy-
draulic oil circuit and thus also the pressure of the coating
material.
A pressure change when the same tip is used also leads to a
change in the amount of paint atomized.

2.2.2 FILTERING
Sucient ltering is required for fault-free operation. To this
purpose the unit is equipped with a suction lter (Item 1) and
an insertion lter in the spray gun (Item 2). Regular inspec-
tion of these lters for damage or soiling is urgently recom-
mended.
A high-pressure lter (Item 3) -available as accessory- is rising
up the ltering surface and will make the work more comfort-
able.
