2 Use
2.1 Proper use
The pumps are intended exclusively for transferring gases and vapors.
Responsibility of the owner
Operating parameters and
conditions
Only install and operate the pumps in accordance with the operating pa-
rameters and conditions described in Chapter
4 Technical data .
Protect compressors with a pressure relief device between the pressure
side of the compressor and the first shut-off valve.
Only fully assembled pumps may be operated.
Make sure that the installation location is dry and that the pump is pro-
tected against rain, splash, gushing and drip water as well as from other
contaminants.
The tightness of the connections between the pipes of the application and
the pump (or the connection of the pump) is to be checked at regular inter-
vals. Leaky connections carry the risk of releasing dangerous gases and
vapors from the pump system.
Requirements for the transferred
medium
Before transferring a medium, check whether the medium can be trans-
ferred danger-free in the specific application.
Before using a medium, check the compatibility of the media-contacting
components (see
4 Technical data ) with the medium.
Risk of dangerous gas mixtures during pump operation if the sealing lip
breaks: Depending on the medium being transferred, breakage of the seal-
ing lip can result in a dangerous mixture if the medium mixes with the air in
the compressor housing.
Only transfer gases that remain stable under the pressures and tempera-
tures that arise in the pump.
2.2 Improper use
The pumps may not be operated in explosive atmospheres.
The pumps are not suitable for transferring:
§
Dusts
§
Liquids
§
Aerosols
§
Biological and microbiological substances
§
Fuel
§
Explosives and flammable material
§
Fibers
§
Oxidants
§
Food
Pumps that can produce both vacuum as well as overpressure may not be
used to simultaneously produce vacuum and operating pressure.
No operating pressure may be applied to the suction side of the pump.
