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 fully assembled 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 range (see
Chapter 4).
The pumped medium should not contain particles as these can prevent the
pump from working correctly. If this cannot be ensured, a < 50 m 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 a potentially explosive atmosphere.
The maximum ambient temperature must not exceed 40°C.
Do not use the pump controller in a damp environment or under condensing
conditions.
The controller must be protected against contamination, and contact with
liquids, solvents or vapours must be avoided.
The pump controller must only be operated when adapted to meet the ESD
(Electrostatic Discharge) safety standards.
Do not establish uncontrolled connections between the controller and conduc-
tive cables and materials.
For special modifications to the pumps outside the standard technical specifi-
cations please contact a 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 preven-
tion 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.
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.
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 for han-
dling 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 accord-
ance with the applicable environmental protection regulations. Ensure adher-
ence 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- ronmen-
tally-appropriate manner. Use appropriate waste collection systems
for the disposal of end-of-life equipment. Used pumps contain
valuable recyclable materials.

Accuracy/reproducibility
The accuracy of the calibrated metering pump is appropriately characterised
by the maximum absolute error A (dependent on the nominal value) and the
maximum relative error B (dependent on the setting value):
max. inaccuracy ≤ (A + B)
FEM 1.02
Error Value
Absolute error A ≤ ±0.1% of nominal value
Relative error B ≤ ±1.0% of setting value
Tab. 10
FEM 1.09
Error Value
Absolute error A ≤ ±0.1% of nominal value
Relative error B ≤ ±1.0% of setting value
Tab. 11
Example: FEM 1.09; the nominal value for stroke volume is 500 µl
For a setting of 260 µl, the accuracy should therefore be within the following
error limits:
Inaccuracy ≤ (±0.1% x 500 µl) + (±1.0% x 260 µl)
≤ (±0.5 µl) + (±2.6 µl)
≤ ±3.1 µl
≈ ±1.2% of setting value
Under constant environmental conditions the pump achieves a reproducibility
of less than ±1%.
Greater inaccuracies may occur for fluids with a viscosity of >
150 cSt or with a tendency to outgas. Appropriate adjustments
may be made during calibration.
The accuracy of the pump is ultimately a matter of the meas-
urement and pumping system and the parameters with which
the pump is operated. The hose types used and the design of
the hose end at the pressure side play an important part in
precise metering.
FEM 1.02 ... SM-2 and FEM 1.09 ... SM-2 are not calibrated in the factory.
The pump must be calibrated electronically via the controller in the customer
system.
The flow rate may differ from the calibrated value in some applications. This is
influenced by the following factors: type of medium, its viscosity, density and
temperature, pressure and installation type (e.g. cross-section constrictions).
For accurate metering it is therefore recommended that the metering pump be
calibrated.

Fig. 3: Pump assembly
Stepping motor diaphragm metering pumps are based on reciprocating dis-
placement pump technology. The elastic diaphragm (4) is moved up and down
by the eccentric (5) and the connecting rod (6). In the downward 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).

FEM … -Version (standard version)
This pump type represents this product in its simplest form and is intended for
continuous delivery at an exact delivery rate.
FEM … .27-Version (with overpressure limitation)
If the metering pump is operating against a closed system, the delivery pres-
sure quickly exceeds the maximum permissible values. To prevent this hap-
pening, an overflow valve is integrated in the top part of the pump head. If the
pressure exceeds the variable limit range (min. 0.5 to max. 6.0 barg), the
valve opens and the liquid circulates from the pressure side to the suction side
via an internal bypass system. This prevents any further rise in pressure.
FEM … .55 version (with single-stroke metering)
The .55 version was specially developed for the KNF stepping motor partial
stroke controller FE Z5. The pumps have a Hall effect sensor for determining
the position of the diaphragms. This is needed during partial stroke metering
or with customer-specific operating profiles.
Please note:
The FEM … .55 is compatible with KNF controllers FE Z4
and FE Z5.
The FE Z5 stepping motor partial stroke controller from
KNF can only be used in combination with the FEM ... .55.
FEM … .55 RC version (single-stroke metering incl. controller)
In the .55 RD version the FE Z5 stepping motor partial stroke controller from
KNF is integrated in the pump and is supplied as a single unit.
Detailed information can be found in the relevant operating instructions.
The stepping motor controllers from KNF are available as accessories, see
accessory list in chapter 10. Two different controllers are available.
Stepping motor controller FE Z4 2-phase stepper
standard controller, single speed controller for variable delivery volume,
pulse input for maximum programming capability etc.
Stepping motor partial stroke FE Z5 Dispense
partial stroke controller, partial stroke metering using potentiometer or an-
alogue signals possible, alarm output etc.
More information about the functionality of the KNF controllers FE Z4 and FE
Z5 can be found in the relevant operating instructions.
