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 ensured,
a < 50 μm filter with a 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 specifica-
tions, please contact your KNF technical adviser.

Translation of original Operating and Installation Instructions 4
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.
Ensure that the old appliance is disposed of in an envi-
ronmentally-appropriate manner. Use appropriate waste
collection systems for the disposal of end-of-life equip-
ment. Used pumps contain valuable recyclable materials.

Translation of original Operating and Installation Instructions 5
The pumps are in accordance with the requirements of the guide-
lines 2011/65/EU (ROHS2)
The pumps conform to 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
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 (operation with elec-
tronic control FE Z6):
▪EN 61000-6-3 (incl. EN 55022 / EN 55011)
The pumps must only be serviced and repaired by the relevant
KNF Customer Service team.

Supplying the magnetic coil with the specified electrical voltage
(see Chapter 4) produces a magnetic field. This magnetic field
pulls the armature (12) and the attached diaphragm (10) back to an
adjustable limit stop. This causes the diaphragm chamber to be
filled with the pumped medium via the inlet (2). In the upward
stroke, the spring tension on the diaphragm forces the medium out
of the pump head via the outlet (1). Once the upward stroke is
completed, the spring (11) pushes the diaphragm into the dia-
phragm chamber until the next pulse. This closes the suction and
pressure lines. The stroke volume of the pump can be adjusted via
the limit stop. The height of the limit stop is adjusted by turning the
calibrating screw (9).

6. Installation and connection
Install the pumps only under the operating parameters and condi-
tions described in Chapter 4 Technical Data.
Observe all safety precautions (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)
Fig. 3: Mounting dimensions FMM 80
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.
Generally speaking, the pump can be mounted in any installa-
tion position. For maximum precision and rapid venting, install
pump in the optimum position (Fig. 4: Optimum installation po-
sition).

Translation of original Operating and Installation Instructions 10
6.2. Electrical connection
Only have the pump connected by an authorized specialist.
Only have the pump connected when the power supply is
disconnected.
The electrical installation must be fitted with a device that
disconnects the magnetic coil from the mains (acc. to EN
60335-1)
When connecting the device to a power source, the relevant
norms, directives, regulations and technical standards must be
observed.
Connecting the pump
Make sure that the power supply data match the data on the
motor's type plate. The current consumption can be found on
the type plate.
The supply voltage must not deviate more than ±10% from the
specifications on the type plate.
Connect the voltage supply cables to the two pump leads.
The polarity is irrelevant.
CAUTION
Do not connect the pump to a continuous direct
voltage. Information on the control signal (see
Chapter 7).
As a consequence of the built-in transient voltage
suppressor, the special requirements for the con-
trol electronics must be observed (see Chapter
7.2).
