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.
Only pumps that are fully assembled and in the condition as delivered 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.
Check the tightness of the connections between the pipes of the applica-
tion and the pump (or the connection of the pump) at regular intervals.
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 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 or the surroundings.
Only transfer gases that remain stable under the pressures and tempera-
tures that arise in the pump.
2.2 Improper use
The pumps are not allowed to be operated in explosive atmospheres.
The pumps are not suitable for delivering:

Pumps that can generate both a vacuum and overpressure must not be
used for the simultaneous generation of a vacuum and overpressure.
This function can be made possible on a project basis following consulta-
tion with KNF Customer Service.
No overpressure may be applied to the suction side of the pump.
This function can be made possible on a project basis following consulta-
tion with KNF Customer Service.
