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
subsequent owners of the pump.
Customer-specific project pumps (pump models which begin with
"PL" or "PML") may differ from the Operating and Installation
Instructions.
In the case of project pumps, take note of any additionally
agreed specifications.

It also indicates the possible consequences of failure
to observe the warning. The signal word (e.g. "Warn-
ing") indicates the level of danger.

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, Technical data.
Only completely installed pumps may be taken into service.
Before transferring or metering 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, pump housing, diaphragm and valves with the
medium.
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 < 100 m with sufficiently large filter area must be
used upstream of the pump.
The .51 versions of our diaphragm liquid pump range have been
certified by NSF according to the standard NSF/ANSI 169 and are
therefore suitable for use with foodstuffs without any restrictions.
All materials used have been checked through a series of toxico-
logical tests. In order to ensure that the food grade quality is main-
tained, NSF will carry out a yearly audit checking our certified
products.
Only the pumps marked with ".51" are NSF certified. and contain a
defined material combination that also has a FDA certificate of
conformity.
NSF: National Sanitary Foundation
FDA: Food and Drug Administration
ANSI: American National Standard Institute
* Pumps with other customer-specific certified material combinations are
available on request.

Diaphragm liquid pump NF 100 Use
KNF Flodos BA_NF100_EN_10_067676.docx
Translation of original Operating and Installation Instructions 4
All certified diaphragm liquid pumps are clearly marked with
“.51” in the type designation along with the NSF logo on the
type plate. If either or both of these markings are missing, the
pump is not certified.
Because the cleaning requirements of the diaphragm liquid
pumps depend on the application, KNF is unable to guarantee
that they can be cleaned. The responsibility for cleaning there-
fore lies with the user. While the NSF/ANSI 169 standard regu-
lates OEM products, it does not define cleaning methods for
specific OEM products.
All parts in contact with the medium can be replaced as spare
parts without losing the certification. Component parts cannot
be traded as certified parts. When replacing parts/assemblies
only use original KNF parts.
2.2. Improper use
DANGER
The pumps must not be operated in an explosive
atmosphere.
For special modifications outside the standard technical specifica-
tions, please contact your KNF technical adviser (see last page for
telephone number).

Translation of original Operating and Installation Instructions 5
3. Safety
Observe the safety precautions in Chapters
6. Installation and connection and 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
contain valuable recyclable materials.

The pumps comply with the fundamental requirements of Directive
2011/65/EU (RoHS2).
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
commissioned until such time as it has been determined that the
machine in which the partly completed machinery is to be assem-
bled 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:

Fig. 2: Operating principle
The diaphragm liquid pumps are based on reciprocating displace-
ment 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
hermetically seals off the working chamber (3) from the pump drive
(7).
NF 100 version (fixed flow rate)
This pump type represents this product in its simplest form and
transfers media at the fixed flow rate.
NF 100.27 version (fixed flow rate with overpressure limiting)
If the diaphragm liquid pump is operating against a closed system,
the delivery pressure quickly exceeds the maximum permissible
value. To prevent this from happening, an overflow valve is inte-
grated in the top part of the pump head. If the pressure exceeds
the adjustable limit range (min. 1.5 to max. 6.5 barg), the valve
opens and the liquid circulates from the pressure side to the suc-
tion side via an internal bypass system. This prevents any further
pressure rise.
