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-
conditions
rameters and conditions described in Chapter 4 Technical data and Chap-
ter 2.3 Use in potentially explosive areas.
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.
The pump is suitable for transferring potentially explosive atmospheres
and for operation in potentially explosive atmospheres.
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-
medium 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.
Make certain that no risk of explosion arises even in extreme operating sit-
uations (temperature, pressure) and in the event of system breakdowns.
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 suitable for use below ground.
The pumps are not suitable for transferring:

Pumps that can produce both vacuum as well as overpressure may not be
used to simultaneously produce vacuum and overpressure.
This function can be made possible on a project basis upon consultation
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 upon consultation
