1. About this document
1.1. Use of the Operating and Installation Instruc-
tions
The Operating and Installation Instructions are part of the pump.
Forward the Operating and Installation Instructions to any sub-
sequent owners of the pump.
Customer-specific project pumps (pump models which begin with
"PL" or "PML") may differ from the Operating and Installation In-
structions.
In the case of project pumps, take note of any additionally
agreed specifications.
1.2. Symbols and markings

WARNING
This symbol indicates a potential danger.
It also indicates the possible consequences of failure
to observe the warning. The signal word (e.g. "Warn-
ing") indicates the level of danger.
Here you will see actions for avoiding the danger
and potential consequences.

2. Use
2.1. Intended use
The pumps are intended for transferring and metering liquids.
Owner's responsibility
Only install and operate the pumps under the operating parameters
and conditions described in Chapter 4 About this document, Tech-
nical data.
Only completely installed pumps may be taken into service.
Before transferring or metering a medium, check whether the me-
dium can be transferred 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 medium should not contain particles as these can
prevent the pump from working correctly. If this cannot be guaran-
teed, a filter < 50 m with sufficiently large filter area must be used
upstream of the pump.
Filters may be ordered as accessories, see Spare Parts and
Accessories (Chapter 10).
2.2. Improper use
DANGER
The pumps must not be operated in an explosive
atmosphere.
Please contact your local KNF partner for special designs that
are not included in the technical specification (www.knf.com).

Translated from the Original Operating and Installation Instructions 4
3. Safety
Observe the safety precautions in Chapter s
6. Installation and connectionand 7.Operation.
The pumps are built according to the generally recognised rules of
technology and in accordance with the pertinent occupational
safety and accident prevention regulations. Nevertheless, dangers
may occur during their use which may 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.
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 all personnel have read and understood the Oper-
ating and Installation Instructions, and in particular the "Safety"
Chapter .
Always ensure adherence to all pertinent accident prevention and
safety regulations when working on and operating the pump.
When transferring dangerous media, observe the safety regula-
tions for handling such media.
Always ensure adherence to all information stickers on the pumps,
such as flow direction arrows and type plates, and keep stickers in
legible condition.
All replacement parts should be properly stored and disposed of in
accordance with the applicable environmental protection regula-
tions. Ensure adherence to the pertinent national and international
regulations. This especially applies to parts contaminated with toxic
substances.
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.

Diaphragm liquid pump NF 5, NFB 5 Safety
KNF Flodos AG BA_NF5_NFB5_EN_01_172971.docx
Translated from the Original Operating and Installation Instructions 5
The pumps comply with the fundamental requirements of Directive
2011/65/EU (RoHS2).
The pumps comply with the safety requirements regarding electro-
magnetic compatibility in Directive 2004/108/EC.
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.
The essential requirements of Annex I of Directive 2006/42/EC
(general principles) are applied and observed.
The following harmonised standards are met:
NF 5 DC-M
EN 55022
EN 55011
NF 5 DCB / DCB-4
EN 61000-6-2
EN 61000-6-3 (incl. EN 55022 / EN 55011)
NFB 5 DCB / DCB-4
EN 61000-6-2
EN 61000-6-3 (incl. EN 55022 / EN 55011)
All repairs to the pump(s) must be carried out by the relevant KNF
customer service team.
Only use genuine parts from KNF for servicing work.

In the case of type NF 5 DCB-4 the supply voltage is not de-
signed for operation with pulse-width modulated voltages
(PWM).
However, a PWM signal (frequency 500Hz or higher) can be
used to control the control voltage.

Fig. 2: Pump assembly
diaphragm liquid pumps are based on reciprocating displacement
pump technology. The elastic diaphragm (4) is moved up and
down by the eccentric (5) and the connecting rod (6). In the down-
ward stroke it aspirates the medium to be transferred via the inlet
valve (2). In the upward stroke the diaphragm pushes the medium
out of the pump head via the outlet valve (1). The diaphragm her-
metically seals off the working chamber (3) from the pump drive
(7).
NFB 5 Version (double-headed pump, see Fig. 3)
This pump type has two NF5 pump heads that can be operated individu-
ally or or in parallel connection (see Chapter 6.3.2).

6. Installation and connection
Only install the pumps under the operating parameters and condi-
tions described in Chapter 4,Technical data.
Observe the safety precautions (see Chapter 3).
