There are no special requirements as regards the quality of the air pressure supplied to the
reciprocating pump.
- Condensation and residue oil from the compressor are trapped
(pressure tank, air filter)
- Lubrication of compressed air not necessary
- Temperature of compressed air 10° C to 50° C
When compressed air is used for fluid atomising, a filter regulator, branched off from the main
compressed air supply – 16 in functional diagram – must be installed upstream.
- Efficient flow rate
at 6 bar and 25m/s > 32 m3/h
- Air inlet pressure 16 bar
- Air and ambient temperatures 0° to 50°C
EXHAUST AIR SILENCER
Without a silencer the sound emission of a reciprocating pump operated by air pressure is
high [ > 100 dB(A) ] and causes damage to hearing. Since there is a relationship between
sound absorption and icing of the reciprocating pump control system, it is not possible to lower
the sound pressure level as much as desired (not 70 dB(A)].
All MERKUR 2000 reciprocating pumps are therefore equipped with appropriately
dimensioned silencers.
The reciprocating pumps may not be operated without the silencer.
The silencer must not be screwed off during operation.
- The decision to wear ear protection depends on the operating pressure and the
resulting sound level.
The air pressure must be free from any substances that may interfere with
paint spraying, like silicone or oil.
- This also applies to component parts of the air pressure supply.
See "Technical Description of Product B.6.20.44-P", page 05
for more detailed information on the sound level.
