Diaphragm Pump N 035 E About this document
1. About this document
1.1. Using the Operating and installation instructions
The operating and installation instructions are part of the pump.
Pass on the operating and installation instructions to the next
owner.
Project pumps
Customer-specific project pumps (pump models which begin with
“PJ” or “PM”) may differ from the operating and installation instructions.
For project pumps, also observe the agreed upon specifica-
tions.

Diaphragm Pump N 035 E Use
2. Use
2.1. Proper use
The pumps are exclusively intended for transferring gases and
vapors.
Owner's responsibility
Operating parameters and
conditions
Requirements for
transferred medium
Only install and operate the pumps under the operating parameters
and conditions described in Chapter 4, Technical data.
Before using a medium, check whether the medium can be transferred danger-free in the specific application case.
Before using a medium, check the compatibility of the materials of
the pump head, structured diaphragm and valves with the medium.
If combustible media are used: Hazard of fires and explosions due
to excessively high media temperature:
Be aware that the pumps are not designed to be explosion-
proof.
Make sure the temperature of the medium is always sufficiently
below the ignition temperature of the medium, to avoid ignition
or explosion. This also applies for unusual operational situations.
Note that the temperature of the medium increases when the
pump compresses the medium.
Hence, make sure the temperature of the medium is suffi-
ciently below the ignition temperature of the medium, even
when it is compressed to the maximum permissible operating
pressure of the pump. The maximum permissible operating
pressure of the pump is stated in the technical specifications
(Chapter 4).
If necessary, consider any external sources of energy, such as
radiation, that may add heat to the medium.
In case of doubt, consult the KNF customer service.
Only transfer gases which remain stable under the pressures and
temperatures occurring in the pump.
2.2. Improper use
The pumps may not be operated in an explosive atmosphere.
The pumps are not suitable for transferring dusts.
The pumps are not suitable for transferring liquids.

Diaphragm Pump N 035 E Safety
3. Safety
Note the safety precautions in sections 6. Installation and
connection, and 7. Operation.
The pumps are built according to the generally recognized rules of
technology and in accordance with the occupational safety and
accident prevention regulations. Nevertheless, dangers can result
during their use which lead to injuries to the user or others, or to
damage to the pump or other property.
Only use the pumps when they are in a good technical and proper
working order, in accordance with their intended use, observing the
safety advice within the operating and installation instructions, at all
times.
Personnel
Working in a safety-
conscious manner
Handling dangerous media
Environmental protection
Standards
Make sure that only trained and instructed personnel or specially
trained personnel work on the pumps. This especially applies to
assembly, connection and servicing work.
Make sure that the personnel has read and understood the operating and installation instructions, and in particular the "Safety"
chapter.
Observe the accident prevention and safety regulations when
performing any work on the pump and during operation.
When transferring dangerous media, observe the safety regulations when handling these media.
Store all replacement parts in a protected manner and dispose of
them properly in accordance with the applicable environmental
protection regulations. Observe the respective national and international regulations. This especially applies to parts contaminated
with toxic substances.
The pumps conform to the safety regulations of the EC Low Voltage Directive 2006/95 EC, and the EC Directive 2004/108 EC
concerning Electromagnetic Compatibility.
The following harmonized standards have been used:
IP20 IP44
EN 55014 EN 55014
EN 61000-3-2/3 EN 61000-3-2/3
EN 60335-1 EN 60204-1

Customer service and
repairs
KNF N 035 E e 08/09 Translation of the original Operating and installation instructions 4
Only have repairs to the pump carried out by the KNF Customer
Service responsible.
Use only genuine parts from KNF for servicing work.
