Information about the operating manual
This manual provides important information on how to work with the device safely and efficiently.
The manual is part of the device and must always be kept in the immediate proximity of the device
so that it is accessible to the personnel at all times.
The personnel must have read and understood this manual before starting any work. Compliance
with all specified safety information and instructions is a basic requirement for safe working condi-
tions.
In addition, the local occupational safety regulations and general safety rules apply for the area of
application of the device.
Due to optional finishing variants, it is possible that the figures shown in this operating manual
deviate from your device.
Information about explosion protection
Many of our competitors have been marking their products with the Ex symbol as a matter of prin-
ciple for some time now.
At Krautzberger we do not do that.
We engineer and manufacture our products in line with currently applicable directives.
If the labelling on the product is required, it is affixed to the product as the result of the necessary
analysis of ignition sources. If no labelling is affixed, the analysis of ignition sources and previous
experience with the assessment of the suitability of products for use in a potentially explosive area
have shown that the product described in this operating manual does not represent a potential
source of ignition, with the exception of an electrostatic charge.
Taking into account the potential equalisation (provided by proper earth connection), the use in an
area at risk for explosions is permitted in accordance with the currently valid directives.

1 Function and identification
1.1 Function
The MP-520 is an air-operated diaphragm pump.
By changing the pressure in the air supply, the conveying capacity of the diaphragm pump can be
seamlessly regulated.
As soon as the set material pressure has been reached, the diaphragm pump switches off auto-
matically. The material pressure is maintained until material is extracted at the extraction point.
The diaphragm pump switches on automatically and keeps the set material pressure constant.
It is optimally suited for conveying paints, oils, etc.

ardship for the protection of the user, the personnel or third parties.
Owner responsibilities
The machine is used in an industrial environment. The owner of the machine is therefore subject to
the obligations as stipulated by the Occupational Health and Safety Act.
In addition to the safety information in this manual, the country-specific safety, accident prevention
guidelines and environmental protection regulations, applicable at the site of implementation of the
machine must be adhered to.
Furthermore, the owner is responsible for making sure that the machine is always in perfect tech-
nical condition. Therefore, the following applies:
nThe owner must ensure that the maintenance intervals described in this operating manual are
adhered to.
nThe owner must have all safety equipment checked regularly for functionality and complete-
ness.

The MP-520 diaphragm pump is a pump operated with compressed air and is used exclusively:
nfor the conveying of liquid and low-viscosity coatings from non-pressurised storage con-
tainers.
nfor the supply of material to spray guns. automatic spray guns, metering devices and similar.
It is mainly used for painting and coating procedures.
The intended use also includes the compliance with all the information in this manual.
2.6 Predictable misuse
Any use beyond the intended use or any other use constitutes misuse.
nOnly carry out the installation and start-up in accordance with the steps described in these

nEnsure that the utilised hose lines fulfil the requirements with respect to pressure, chemical,
and mechanical loads.
nThe chemical resistance of the materials which we use cannot always be assessed with
authority due to the large number of fluids, concentrations, temperatures and impurities used.
For this reason, please test the suitability because we cannot extend any respective guaran-
tees.
nAdhere to the safety data sheets of the spray medium manufacturer.
nOnly use the manufacturer's OEM parts.
nOnly operate the diaphragm pump after fastening it properly to a suitable supporting structure.
nOnly operate the diaphragm pump in compliance with the values specified in (
Ä Chapter 12
‘Technical data’ on page 44).
nMake sure that the connected compressed air is oil-free and free from solid matter.
nOperate the diaphragm pump with processed, dried compressed air (air quality pursuant to
DIN ISO 8573-1: quality class 4).
nNever point the compressed air at living beings.
nThe conformity of the product is voided in case of structural modifications of the diaphragm
pump.
nDo not use the diaphragm pump in the food or pharmaceutical sectors.
WARNING!
Improper of the diaphragm pump can lead to hazardous situations.
No claims of any kind can be asserted due to damage resulting from misuse!
2.7 General safety instructions
WARNING!
Risk of death, risk of injury or property damage due to hazardous media!
Potential consequences: The application of hazardous media can lead to death, severe inju-
ries or property damage.
When handling hazardous substances, ensure that the current safety data sheets of the haz-
ardous substance manufacturer are available. The necessary measures can be derived from
the content of the safety data sheet. Since the hazardous potential of a material can be reas-
sessed at any time due to new lessons learned, the safety data sheet must be checked regu-
larly and replaced if necessary.
The system owner is responsible for the presence and the up-to-date status of the safety data
sheet and the associated generation of the risk assessment of the effected workstations.

WARNING!
Hazardous media / contamination of persons and equipment
Possible consequences: Fatality or serious injuries, property damage
– Ensure the resistance of the device against the medium that is to be conveyed
– Always adhere to the safety data sheet of the medium that is to be conveyed The system
owner is responsible that the safety data sheet is present and up-to-date
– The safety data sheet of the conveyed medium is always authoritative for the initiation of
countermeasures in case of a leak of the conveyed medium
– Adhere to the general limitations with respect to viscosity limits, chemical stability and
density
WARNING!
Risk of injury due to hot surfaces!
The surfaces of components can become very hot during operation. Direct contact with hot
surfaces causes severe skin burns.
Note:
– Always wear protective clothing and protective gloves for all work in the vicinity of hot
parts.
– Ensure that all surfaces have sufficiently cooled down prior to starting any work.
