2 Use
2.1 Proper use
The pumps are intended exclusively for transferring gases and vapors.
Responsibility of the owner
Only install and operate the pumps in accordance with the operating pa-
rameters and conditions described in Chapter 4 Technical data .
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.
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 diaphragm
breaks: Depending on the medium being transferred, breakage of the di-
aphragm 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 aggressive media. For aggressive media,
pumps from the KNF product line are available – please contact us.
Pumps that can produce both vacuum as well as overpressure may not be
used to simultaneously produce vacuum and overpressure.
No overpressure may be applied to the suction side of the pump.
Pumps with capacitor motor are not intended for operation with a fre-
quency converter.
