Operating and Installation Instructions 3
2. Use
2.1. Intended use
KNF pumps in the NMS030 range are to transfer, evacuate and
compress gases.
Owner's responsibility
Only install and operate the pumps under the operating parameters
and conditions described in Chapter 4, Technical data. Only com-
pletely installed pumps may be taken into service.
Before using a medium, check whether the medium can be trans-
ferred danger-free in the specific application case.
Before using a medium, check the compatibility of the materials of
the pump head, pump housing, diaphragm and valves with the me-
dium.
The temperature of the medium must lie within the permissible
temperature range (see Chapter 4).
The transferred gas should not contain particles as these can pre-
vent the pump from working correctly. If this cannot be guaranteed,
a filter < 100 m with sufficiently large filter area must be used up-
stream of the pump.
See the type- plate or data sheet for full electrical and pneumatic
data.
2.2. Improper use
DANGER
The pumps must not be operated in an explo-
sive atmosphere.
The pumps are not suitable for transferring dusts and liquids.
Please contact your local KNF partner for special designs that
are not included in the technical specification (www.knf.com).

accordance with the applicable environmental protection regula-
tions. Observe the respective national and international regula-
tions. This especially applies to parts contaminated with toxic sub-
stances.
Dispose of all packaging in an environmentally-appropriate
manner. The packaging materials are recyclable.
Dispose of end-of-life equipment in an environmentally
friendly manner. Use appropriate waste collection systems
for the disposal of end-of-life equipment. Used pumps con-
tain valuable recyclable materials.
For the purposes of the Machinery Directive 2006/42/EC, pumps
are “partly completed machinery", and are therefore to be regarded
as not ready for use. Partly completed machinery may not be com-
missioned until such time as it has been determined that the ma-
chine in which the partly completed machinery is to be assembled
conforms to the provisions of the Machinery Directive 2006/42/EC.
