1.1. Use of 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.
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.

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.
Pumps must only be operated when fully assembled.
Before transferring or metering a medium, check that it can be
transferred without risk 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
pumped medium.
The temperature of the medium must lie within the permissible
temperature range (see Chapter 4).
The pumped medium should not contain particles as these can
prevent the pump from working correctly. If this cannot be
guaranteed, a filter < 100 m with sufficiently large filter area must
be used upstream of the pump.
2.2. Improper use
The pumps must not be operated in an explosive atmosphere.
For special modifications outside the standard technical
specifications please contact a KNF pump specialist.

Translation of Original Operating and Installation Instructions 4
3. Safety
Note the safety precautions in Chapters 6. Installation and
connection, and 7. Operation.
The pumps are built according to the generally recognized rules of
technology and in accordance with the pertinent 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 in perfect working order and in accordance
with their intended use. Always ensure adherence to the operating
and installation instructions and work in a safety-conscious
manner.
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
operating 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 pumping dangerous media, observe the safety regulations
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
regulations. 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.
Ensure that the pump is disposed of in an environmentally
appropriate manner at the end of its useful life. Use
appropriate waste collection systems for the disposal of
end-of-life equipment. Used pumps contain valuable
recyclable materials.

KNF Flodos AG BA_NF1.60_EN_05_161566.docx
Translation of Original Operating and Installation Instructions 5
The pumps are in accordance with the requirements of the
guidelines 2011/65/EU (ROHS2)
Under Machinery Directive 2006/42/EC, pumps are partly
completed machinery, and as such should not be regarded as
ready for use. The partly completed machinery must not be put into
service until the final machinery into which it is to be installed has
been declared to be in conformity with the provisions of this
Directive. Always ensure implementation and enforcement of the
basic requirements of the Machinery Directive 2006/42/EC
according to Appendix I (General Principles).
The following harmonised standards are met:
NF 1.60 DCB-B / DCB-4B
IEC/EN 61000-6-2
IEC/EN 61000-6-3
NF 1.60 DC
EN 55011
All repairs to the pump(s) must be carried out by the relevant KNF
Customer Service team.
Only use KNF original parts for all maintenance work.

Fig. 2: Operating principle
Diaphragm liquid pumps are based on reciprocating displacement
pump technology. An elastic diaphragm (4) is moved up and down
by the eccentric (5) and the connecting rod (6). During the down
stroke, the diaphragm sucks in the medium through the inlet valve
(2). During the up stroke, it forces medium out of the pump head
through the exhaust valve (1). The diaphragm hermetically seals
off the working chamber (3) from the pump drive (7).
NF 1.60 version (specified flow rate)
This pump type represents this product in its simplest form and
delivers media at the specified flow rate.

6. Installation and connection
Only install the pumps under the operating parameters and
conditions described in Chapter 4, Technical data.
Observe the safety notes (see Chapter 3).
6.1. Installation
Before installation, store the pump at the installation location to
bring it up to ambient temperature.
Mounting dimensions (see Fig. 3 to 5)

Translation of Original Operating and Installation Instructions 10
Make sure that the installation location is dry and the pump is
protected against water in the form of rain, spray, splashes and
drips.
Protect the pump against dust.
Protect the pump against vibration and impact.
The pump can be mounted in any orientation.
Generally speaking, the pump can be mounted in any
orientation. For maximum precision and rapid venting, install
pump as shown in the illustration (Fig. 6).
KNF recommends mechanically decoupling the pump from the
pipework system, e.g. by using flexible hoses or pipes. This
prevents any oscillations of the pump being transferred to the
system.
6.2. Electrical connection
For pumps with direct current motors:
Pump should only be connected by an authorised specialist.
Only connect the pump when the power supply is turned off.
All electrical connection work must adhere to the pertinent
norms, directives, regulations and technical standards.
Connecting the pump
1. Make sure that the power supply data match the data on the
motor type plate. The current consumption can be found on the
type plate.
2. Connect the motor cables. For electrical data see Chapter 4.
Always check polarity of cables.
For DC motors:
red motor lead: +
black motor lead: -
In the case of brushless DC motors:
incorrect polarity may damage the electronics.
