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.

2 Function and identification
2.1 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 automati-
cally. The fluid pressure is maintained until material is extracted at the extraction point. The dia-
phragm pump switches on automatically and keeps the set fluid pressure constant.
It is optimally suited for conveying paints, oils, etc.
