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 conditions.
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 principle 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.

ENGLISH
1 Function and identification
1.1 Function
The MP-400 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 fluid pressure has been reached, the diaphragm pump switches off automatically. The fluid pressure is maintained until material is extracted at the extraction point. The diaphragm pump switches on automatically and keeps the set fluid pressure constant.
It is optimally suited for conveying paints, oils, etc.

3 Safety and responsibility
3.1 Responsibility of the owner
Owner
The owner is the person, who directly operates the machine for commercial or economical purposes or who allows a third-party to use/apply it and who is responsible for the legal product stewardship 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 technical condition. Therefore, the following applies:
n The owner must ensure that the maintenance intervals described in this operating manual are
adhered to.
n The owner must have all safety equipment checked regularly for functionality and complete-
ness.
3.2 Intended use
The MP-400 diaphragm pump is a pump operated with compressed air and is used exclusively:
n for conveying liquid and low-viscosity coating material from depressurised storage con-
tainers.
n for supplying material to automatic spray guns, metering devices and such like.
The intended use also includes compliance with all of the specifications in this operating manual.
3.3 Predictable misuse
Any use beyond the intended use or any other use constitutes misuse.
n Always carry out installation, commissioning, and use in accordance with the steps described
in this operating manual.
n Ensure that the hose lines used meet the requirements with regard to pressure, chemical, and
mechanical loads.
n Always observe the applicable country-specific safety, accident prevention, occupational
safety, and environmental protection regulations etc. for the area of use for the diaphragm
pump.
n The chemical resistance of the materials which we use cannot always be assessed with
authority due to the large number of fluids used, concentrations, temperatures and impurities.
For this reason, please check the suitability as we cannot offer any guarantees in this regard.
n Adhere to the safety data sheets of the spray medium manufacturer.
n Only use the manufacturer's OEM parts.
n Only operate the diaphragm pump in compliance with the values specified in (
‘Technical data’ on page 46).
