CORRECT USE
The diaphragm pumps 003.175-DP are exclusively manufactured for the usual applications in
surfacing technology (to convey coatings or auxiliary agents or for spraying) or similar work.
Any other purpose above and beyond this is considered incorrect use. We are not responsible for
any damage or injury resulting from this; the user bears the sole responsibility in such cases.
Correct use includes observing the operating, maintenance and inspection conditions and
regulations laid down by us.
003.175-DP diaphragm pumps may only be used, maintained and repaired by personnel familiar
with, and trained to recognise the inherent dangers.
The relevant accident prevention regulations as well as safety and medical rules must be observed.
Unilateral changes to the appliance will cause us to waive our responsibility for any damage or injury
caused.
The user is responsible for the correct installation of the appliance.

DESCRIPTION OF FUNCTIONS
The compressed air is supplied to the diaphragm pump Dfrom a pressure tank 1via a pipe or
hose 2and a pressure control valve 3. The air supply from the pressure tank to the diaphragm
pump can be interrupted by the ball cock 4.
The other ball cock 5is used for manually releasing condensation (an automatic steam trap would
be preferable here).
The safety valve 6protects the pressure tank against inadmissible rises in air pressure (e.g. in the
event of heating).
There is also a safety valve 7on the diaphragm pump because as a rule the compressed air supply
Eis not installed for the diaphragm pump only, and because it is obligatory.

Compressor

4 B.6.50.80-B-GB
During operation, compressed air escapes into the atmosphere from the propulsion mechanism of
the diaphragm pump via the integrated sound absorber 8. This unburdens it.
The material (coating or auxiliary agents) is sucked out of a material receptacle 9via the suction
line bl by the diaphragm pump and fed on under pressure via the pipe or hose line bm to the
withdrawal point.
A sieve (dirt trap) bn protects the diaphragm pump against foreign bodies which have unintentionally
entered the material.
COMPONENT PARTS OF APPLIANCE - IMPORTANT INFORMATION
The following must be fulfilled if the appliance is to be considered ready for operation:
DTHE DIAPHRAGM PUMP
For the description of the functions of the diaphragm pump see "Technical Description of
Product B. 6.50.80-P“.
ETHE COMPRESSED AIR SUPPLY
The compressed air supply consists of the compressor, the pressure tank with steam trap,
possibly a compressed air drier and pipeline. The compressed air supply is generally already
available to the user.
 If a compressed air supply must be installed the relevant accident prevention regulations,
safety rules and user information, in particular information from the compressor
manufacturer, must be applied.
There must be a flexible connection between the diaphragm pump and the compressed air line
(avoids fractures caused by vibrations). A hose line is most suitable
 nominal diameter 13 or bigger
 operational pressure = max. mains pressure, preferably•16 bar
 air and local temperature -20 to 50 °C
 free of materials detrimental to paint such as silicone
In areas with a danger of explosion the compressed air line and the hose line must be
electrically conductive (to avoid electrostatic charging).
- leakage resistance < 106Wto earth.
The pressure control valve is in most cases directly fitted to the diaphragm pump.
 efficient rate of flow
at 6 bar and 25 m/s > 114 m³/h
 air inlet pressure 16 bar
 air and local temperature 0° C to 50 °C

5 B.6.50.80-B-GB
It goes without saying that the pressure control valve can be situated between the hose line
and the compressed air line.
The manometer connected 3.1 in function diagram enables exact setting and control of
the air pressure required.
 display range 0 to 16 bar
 air and local temperature 0 to 50 °C
 damped construction
A shutoff mechanism (e.g. ball cock) should be fitted between the pressure control valve and
the hose line in all cases, or between the hose line and the compressed air line. This enables a
quick and safe diaphragm pump switch-off before operating pauses, maintenance work and in
cases of breakdown.
There is no change to the value set on the pressure control valve:
 Nominal pressure 16 bar
 Material CuZn, nickel-plated
For ball cocks the following must be observed: stopcock transverse to flow direction =
pipe is closed off
There are no special requirements as regards the quality of the compressed air supplied to the
diaphragm pump.
 condensation and residue oil from the compressor are trapped
(pressure tank, compressed air filter)
 oiling of compressed air not necessary
 temperature of compressed air 10°C to 50 °C
FEXHAUST AIR SOUND ABSORBER
The sound emissions of a compressed air powered diaphragm pump is damaging to hearing in
the absence of a sound absorber [> 100 dB(A)]. Every diaphragm pump is therefore fitted with
an integrated sound absorber.
Do not use PTFE or hemp to seal connections (causes pressure control valve
malfunction due to residue from compressed air supply).
In painting processes the compressed air must be free of substances which could
lead to the formation of craters (oil, silicone).
- This also applies to component parts of the compressed air supply.

6 B.6.50.80-B-GB
As there is a connection between sound absorption and the formation of ice on the diaphragm
pump control system, the sound level cannot be reduced with a sound absorber as much as
would be desired [not < 70 db(A)].
The diaphragm pump may not be used without the sound absorbing components.
- The decision to wear ear protection depends on the operating pressure and the
resulting sound level.
GMATERIAL SUCTION SYSTEM
The cross section of the suction line is so measured that
material with a kinematic viscosity of up to 750
mm²/s(cSt) can be sucked without difficulty by the
diaphragm pump. Higher viscosity can result in difficulties
ranging from a reduction in the suction performance to
interrupted suction, identifiable by an increasingly greater
fall in pressure during the change of direction (pulsating
pressure).
 Measures for improvement are:
keeping the suction line as short as
possible or a short
suction hose with a larger cross section.

Suction system characteristics are:
 Electrically conductive, maximum permissible resistance 3 . 104 W/m (tested to ISO 8031)
and leakage resistance to earth < 106W.
Suitable for use in hazardous locations.
 The individual parts of the suction system are designed to withstand an excess pressure of
12 bar (- Suitable for suction heights of up to 8.5 m).
 The suction hose and the suction sieve are resistant to the usual solvents in the surface
coating and silicone-free.
 Minimum nominal diameter 25
See "Technical Description of Product B.6.50.80-P-
GB", page
04 for more detailed information on the sound level.

Temperature of material 10 °C to 85 °C
 Sieve mesh size 1.8
For a fixed installation the connections diaphragm pump
material loop pipe or diaphragm pump pressure tank
must be flexible (avoids fracture caused by vibrational
stresses). The characteristics of the suction pipe are the
same as those for the suction equipment.
The diaphragm pump may not be pressurised from the suction side.
- This could destroy important functional components.
The viscosity of thixotropic materials is reduced when
stirred; this can have the effect that the suction
performance of the diaphragm pump is improved
(amongst others).
The agitator is fixed to the pipe of the suction device. The
clamp (bracket) must be fixed to the vessel rim. This
ensures that the agitator propeller is in the right position
in relation to the vessel wall, the base and the suction
pipe, and that frictional contact is impossible.
The agitator is pneumatically driven, max. allowable input pressure 6 bar. Rotational speeds
can be adjusted using the butterfly valve connected. The user should determine the optimal
rotational speed for the material used.
 The agitator propeller is surrounded by an external protection ring
- Techn. Product Description B.18.10.05-P
HMATERIAL PRESSURE SYSTEM
The material pressure system is normally composed of a hose and/or pipeline.
For surface coating, the hose must have the following characteristics:
 Electrically conductive, max. permissible resistance 3 x 104W/m (tested to ISO 8031).
 The inside pipeline coating must be resistant to normal solvents, the outer coating resistant
under certain conditions.

 The following applies to the surface coating :
resistant to normal solvents and free from
materials detrimental to paint use such as
silicone.
In an expanded material pressure system and in cases where the pressure system is
influenced by heat (sunrays, heating, etc.) it is necessary to fit a suitable non-return
valve in the pressure pipeline (to prevent damage caused by heat expansion).
